[ad_1]

Author Evgeny Aprelev Reading 4 min Views 2.9k.

The architecture of modern buildings and some of the materials from which such buildings are built do not always make it possible to install air conditioners. To meet the needs of consumers who cannot use classic monoblock or split systems in such premises, a column type of air conditioners was invented. [contents] Column type air conditioners are a high-performance split system that differs in appearance and installation method of the indoor unit. The external unit is no different from the standard split system module, and performs the same functions. Externally, the indoor unit looks more like a refrigerator or cabinet. Sometimes it is called that — a cabinet air conditioner. It is installed on the floor of the room, and the air flow from the unit is directed upwards. This air conditioner has a number of advantages in comparison with the classic air conditioning device, therefore it has gained well-deserved popularity among modern consumers.

Purpose and application

Column air conditioner is designed to create optimal temperature indicators for a person in rooms up to 170 m2. These devices take up a lot of space, so they are most often used:

Stores and other commercial establishments.
Restaurants and other catering establishments.
In the halls of the exhibition halls.
To create a certain temperature regime in warehouses.
In office premises.

By and large, it is difficult to answer where column air conditioners are still used, because they were designed specifically for those places where it is impossible to install other air conditioning systems.

Device and principle of operation

The device of such climate systems is no different from conventional household split systems. The outer block consists of a classic set of elements:

Corps. As a rule, for the manufacture of external blocks of column air conditioners, metal coated with an anti-corrosion compound is used.
compressor. It is thanks to this device that freon is compressed and moves through the «insides» of this climate system.
condenser or heat exchanger. In this device, the hot gas is cooled.
A fan that intensively blows the heat exchanger, forcing the outside air to take the heat removed from the room by freon.

Split system column type The indoor unit, although it looks somewhat unusual, is actually quite a common component of a split system. It consists of:

Metal body in the form of a column.
Evaporator — a heat exchanger in which freon passes from a liquid state to a gaseous state.
The fan, due to which the cooled evaporator is blown. Air streams pass through the heat exchanger and are cooled, thereby cooling the room.
Filter for rough air purification. It is designed to remove mechanical impurities such as dust from air streams.
Capillary tube or throttling device.
Control and protection boards.

Advantages and disadvantages

Column split systems have all the functions of modern air conditioners. These are cooling and heating of air, distribution of air flows through the room with the help of blinds, air purification and much more. Many manufacturers endow their models with a lot of additional features, thanks to which they greatly simplify “communication” with them, and also greatly raise their price. But, in spite of everything, such air conditioners have a lot of significant advantages:

The main advantage is the ease of installation, which does not require special skills.
The abundance of model designs makes it possible to choose the “appearance” of the indoor unit, which will ideally fit into the interior of any home.
High performance enables them to work effectively in rooms up to 170 m2.
Uniform cooling or heating of the room.
ventilation function.
The presence of the LCD screen, which displays the indication of work.
Self-diagnosis and remote control function.

But such split systems also have disadvantages.

Column air conditioners are bulky and heavy. They require a lot of free space.
These climate systems are quite expensive.
Despite the fact that they direct the air flow straight up, the presence of people in the immediate vicinity of the operating device can lead to colds.

Advice:
The column split system has many advantages, but its choice should be approached thoughtfully. In small rooms of our apartments, it is undesirable to use such a unit.

Ventilation in a greenhouse — ways to solve this problem

[ad_1]

Author Evgeny Aprelev Reading 7 min Views 6.4k.

Ventilation in a greenhouse is not a fad, but a necessity, because the correct temperature regime plays one of the most important roles in the successful cultivation of various crops.

Watering, loosening the soil and timely extermination of weeds are no less important, but the greenhouse effect that occurs when moist air is heated can destroy an unripe crop in a matter of hours. Warm and humid air is an ideal microclimate for the development of most fungal diseases, and also makes it possible for an unlimited amount of pathogenic microflora to develop in the soil.

[contents]

To avoid these consequences that are detrimental to the crop, timely ventilation of greenhouses is necessary, which will reduce the temperature and humidity of the air inside the structure. Also, when airing, fresh air enters, which is essential for good plant growth.

The easiest way to ventilate greenhouses

The simplest and most inexpensive way is to manually ventilate greenhouses. Each greenhouse structurally has different windows and transoms. By installing a thermometer and a hygrometer in the building, you yourself, based on their readings, will be able to open or cover the transoms, creating natural supply and exhaust ventilation in the greenhouse.

By independently adjusting the number and area of openings, you can quite effectively ventilate the greenhouse, focusing on the direction of the wind and the external air temperature. Like everything, manual ventilation has its advantages and disadvantages. The main advantage of this method is its low cost. You do not need to buy devices, but you can focus on your experience.

Independently open and close windows and doors when the temperature changes Anyone who has grown plants in a greenhouse at least once knows that one has to open and close the windows a dozen times a day. And here you can’t “break away” from this lesson. And there can be no question of leaving.

Automatic ventilation

Using the experience of summer residents and simple devices, you can easily arrange natural ventilation in automatic mode. How good is automation? Yes to everyone: you will not easily create the necessary conditions for the growth of plants, but you will also make sure that the ventilation is carried out depending on the crop that you will grow in the greenhouse. And it is especially pleasant that the system will practically not need to be monitored.

To date, there are four ways to automate the ventilation of greenhouses:

Using electrical equipment and systems for ventilation.
By installing hydraulic ventilation automation systems in the greenhouse.
Mounting bimetallic ventilation systems.
Integrating automated vents into the design of the greenhouse.

Electrical devices for automatic ventilation

The simplest automatic device for arranging a greenhouse with natural exhaust ventilation is a thermostat with a fan connected to it. The principle of operation of this simple mechanism is as follows: when the temperature rises, the relay is activated and starts the exhaust fan. It will create a small vacuum and suck out heated air from the structure, and fresh air will flow in its place, through natural leaks in the greenhouse structure.

If you provide for the automatic opening of the window at the opposite end of the greenhouse when the fan is turned on, then you can make more efficient ventilation. The fan will drive cool air into the building and lower the temperature and humidity in the greenhouse much faster.

Exhaust fan for polycarbonate greenhouse This ventilation design allows you to quite accurately set the parameters for turning on and off the equipment. Having somewhat complicated the design, you can configure the fan so that it creates a certain force of air flow depending on the temperature inside the greenhouse.

But such a simple and effective design is not without drawbacks. First and foremost is the dependence on electricity. The second disadvantage of electrical equipment for ventilation systems is the complex installation of drives for automatically opening or closing ventilation transoms. Many will say that such systems are reliable and when establishing alternative sources of electricity, dependence on a sudden blackout disappears.

They will say — and it will turn out to be right, but solar panels, as an alternative power source, are expensive and have a rather low efficiency, and a wind generator occupies a large area, is expensive and requires wind. Based on the foregoing, such devices cannot be considered as a complete replacement for the electrical network.

Hydraulic ventilation automation systems

This ingenious invention operates on the principle of communicating vessels, one of which is located in the greenhouse and is connected to a system of levers and a transom. The second vessel is installed on the outside of the greenhouse and is connected to the first hose. That’s the whole structure. The system works like this: when the temperature rises, it affects the liquid inside the vessel located in the greenhouse, it expands and opens the window through the system of levers. The container, located on the outside of the structure, compensates for the pressure, slowing down the sharp opening of the window. As the temperature drops, it also affects the liquid and everything happens in the reverse order.

Such automation of ventilation creates effective natural ventilation of the greenhouse, which is sufficient to maintain the desired temperature balance. In addition, the advantage of the system is complete energy independence and the almost complete absence of the need for constant supervision.

But even here it was not without drawbacks, the main of which is the slow opening and closing of the ventilation windows. The fact is that with a sharp increase in temperature, the inertia of the mechanism can play a trick on you, which will lead to overheating of the air and the death of the crop.

How to choose a hydraulic mechanism for arranging ventilation

Paradoxically, despite the rather serious shortcomings of hydraulic ventilation systems, there is an increased demand for them from gardeners. And demand creates supply, so there are a myriad of options for such devices from different manufacturers. What factors to look for when choosing this unit?

Price category. Efficient hydraulic devices cost a lot. Their price varies from 1.5 thousand rubles. up to 3.5 thousand rubles for one piece. And they are needed for each window.
Each such unit is designed to lift a window of a certain weight, so before buying the model you like, ask the seller how much it can lift and whether it has enough power to lift the window of your greenhouse.
The hydraulic lift has a certain mass, so immediately decide how many kilograms your greenhouse structure can withstand.
Another important factor to be determined before buying this device is whether it can be configured to operate at a certain temperature.

If you immediately determine which device you need before buying, then the efficiency of its work is guaranteed to you.

Master’s advice:
Each hydraulic opener has a specific opening angle. When buying, pay special attention to this.

Making ventilation with the help of such a device is very simple and not financially expensive. The window opening mechanism consists of a lever and two bimetallic plates, which have different expansion coefficients. In simple terms, it works like this: when the temperature rises, one of the plates bends, and pushing the lever opens the window. When the temperature drops, the plate returns to its original position and the window closes.

Simple, cheap, cheerful, but not without flaws. In such a system, it is difficult to calculate the correspondence of plate buckling to a certain temperature.

Air vents for automatically ventilating the greenhouse

This is a new trend in the arrangement of automatic natural ventilation in greenhouses. The automatic window leaf consists of an oil cylinder and a piston, which acts as a transom pusher. When heated, the oil in the cylinder expands and pushes out the piston, which opens the transom. With «exactly the opposite» everything happens when the temperature drops. Since we know from the physics course that oil cannot be compressed, the pusher piston can lift quite a serious weight.

A wonderful and effective invention, and most importantly — affordable. A simple device to install, it will perfectly replace the somewhat outdated, but effective automatic supply ventilation.

If you’re a fan of growing early fresh vegetables or flowers, then get serious about building a ventilation system in your greenhouse, which is essential for growing most crops.

Air conditioning for the kitchen in the apartment: a necessity or a whim of the owner

[ad_1]

Author Evgeny Aprelev Reading 5 minutes Views 10.7k.

Air conditioning is a brilliant invention of mankind, which allows you to create a comfortable microclimate in the premises, regardless of the air temperature outside the window. Already more than 60% of the city apartments of our compatriots are equipped with this wonderful device.

[contents]

As a rule, the air conditioner is installed in the living room or bedroom. Many conscious parents, who have realized the importance of the right microclimate in the development of their own child, install such climatic equipment in children’s rooms. But the kitchens in the homes of our compatriots, as a rule, are not equipped with an air conditioning system. In the framework of this article, we will try to figure out whether air conditioning is needed for the kitchen in the apartment?

Air temperature control in the kitchen

The air temperature in the kitchen is almost always higher than in the rest of the rooms of the house or apartment, since it is in this room on a relatively small area that a lot of devices that emit thermal energy are collected. First of all, it is a gas or electric stove and an oven. Almost every home has an electric kettle and/or coffee maker and microwave. The heat exchanger on the back wall of the refrigerator also releases a lot of heat energy, and unlike other household appliances — all the time. Heat sources

Air conditioning in the kitchen: the reviews of our compatriots about the need for this device are extremely ambiguous. The owners of modern split systems, in principle, agree that an air conditioning system in the kitchen is necessary, but everything depends on the cost of this device. Almost everyone who does not have this device does not consider it necessary to start the struggle for creating the ideal microclimate in their home from the kitchen.

If we add up all the heat emissions from household appliances with a 30-degree heat, which is present in almost the entire territory of our vast territory in summer, then it will immediately become clear that air conditioning in the kitchen is simply necessary.

Many people prefer to use simpler and cheaper devices to combat heat emissions, such as a window fan for the kitchen. Some people try to lower the air temperature in the cooking room by increasing the air exchange by installing an exhaust hood.

It should be understood that an air conditioner and a kitchen hood are household appliances of a completely different orientation. The exhaust hood removes odors and combustion products from the room. Air conditioner — cools the room. To create a good microclimate in the kitchen, it makes sense to install both devices.

Which air conditioner to choose

Despite the fact that there are special requirements for kitchen climate control equipment, choosing an air conditioner for the kitchen is quite simple, and there are several reasons for this:

There is no need to choose a low noise device.
The climate control device does not have to be a multifunctional device.
The device management system can have a minimum number of settings.
In such a room, a device with air heating is not needed.
No inverter controlled device required.

It probably does not make sense to describe all types of air conditioners that can be installed in the kitchen. We will only touch on the shortcomings of one or another type of climatic device when installing a kitchen in a room.

Window monoblock is the cheapest representative of climate technology. The cost of a «non-heating» device of low power (the area of u200bu200bpremises for cooking in our apartments usually does not exceed 15 m²) rarely goes beyond 400 c.u.

The problem of installing a window monoblock is the additional cost of reworking the window, especially if it is metal-plastic.

Mobile air conditioners, according to experts, are not suitable for installation in a cooking room. They occupy precious square centimeters of space and require the removal of warm air. The air duct, of course, can be brought out through the window, but this is not aesthetically pleasing and is not always possible due to the lack of one.

A modern classic split system is a rather expensive device, although it has several undeniable advantages: it does not take up space and is equipped with a good filtration system.

If you are able to part with 1.2 thousand USD (the average price of an inexpensive climate control device with installation), then pay attention to models with serviced filters.

A ducted air conditioner can be considered an ideal solution for creating an ideal microclimate not only in the kitchen, but throughout the apartment, if not for one thing: such a system will require quite serious financial investments in organizing a network of air ducts, creating a false ceiling and purchasing the device itself. In addition, the duct climate device will significantly reduce the height of the ceilings, which in new buildings do not exceed three meters.

When choosing an air conditioner for the kitchen, you should pay attention to models with easy access to the heat exchanger, fan and filter elements. Grease, which is in the air mixture of the kitchen, inevitably settles on the insides of the air conditioner. That is why prevention of kitchen air conditioners should be carried out more often than devices installed in other areas of the home.

Kitchen air conditioners for catering establishments

Problems with fatty deposits on internal surfaces, the evaporator, fan blades and filter elements are inherent not only in household climate control equipment, but also in quite professional devices. In hot shops, air conditioners are installed, mainly wall-mounted and ceiling-mounted with oil-catching filter elements instead of dust ones.

The case of the air conditioner in the kitchen of the restaurant should be easily disassembled and made of a material that is resistant to cleaning agents. Not so long ago, the Mitsuibshi Electric company began supplying the Russian market with climate equipment, specially designed for the kitchens of catering establishments, models of air conditioners. Model PCA-RP125HA

The most popular model of a climatic device for hot catering shops is PCA-RP125HA, which is distinguished by an easily collapsible stainless steel case, the ability to work in the cold season (up to -15 ° C), and an air dehumidification function, which is quite important for kitchens with high moisture release. . Due to its design features, this split system improves the microclimate in the room using the possibility of adding fresh air.

Functional features and design of a bladeless fan

[ad_1]

Author Evgeny Aprelev Reading 7 min Views 2.5k.

The abundance of climate technology presented on the domestic market gives the modern consumer the right to choose almost any device that has the necessary functions to create a favorable microclimate in the room. But, despite this, the fan was and is the most demanded climatic device.

[contents]

Modern industry offers a huge number of fans that differ from each other in appearance, installation method and functionality. But some devices are able to surprise even worldly-wise experts. We are talking about bladeless fans, which use a completely different principle of operation from ordinary fans to create an air flow. What a bladeless fan is and how it works will be discussed in this publication. In addition, a brief overview of several of the most popular models will be made.

Design and principle of operation of the device

Externally, this type of fan resembles a television antenna or interior decoration — there are no moving parts.

The principle of operation of the bladeless fan is based on the «air multiplier» technology.

The air ejected from the nozzle at high speed entrains other air masses due to the vacuum created around the nozzle.
A steady air flow is created, only amplified several times. This slightly modified principle was used by James Dyson when he developed a fan that does not have blades.

The device of a bladeless fan is extremely simple and effective.

The device consists of a frame and a base-stand, in which a high-speed turbine is mounted.
Through the cracks, it draws in air and delivers it to the frame, the cross-sectional shape of which resembles the profile of an airplane wing.
The air ring can be either round or oval.

Passing through the ring and spinning, the air increases the speed of movement by more than 15 times, after which it is thrown out through a narrow slot located along the entire perimeter of the frame. At the exit from it, the air speed can reach 85-90 km / h, which creates a vacuum in the air ring, the space of which is instantly filled with air. It is this effect that creates a powerful and continuous air flow, which, together with the entrained air, can move at a speed of 30-35 km / h. The main structural elements of the fan

As a rule, the force of the air flow created by this device can be changed by increasing or decreasing the rotation of the turbine.

The main advantages and disadvantages of the «invisible fan»

The most important advantage of such devices is safety. Due to the absence of moving parts in the reach zone, such a device will not be able to injure anyone. In addition, it can be noted:

The energy efficiency of such a device. With the same power consumption, bladeless models have 6-8 times more power than conventional fans.
The uniformity and narrow directionality of the air flow, in contrast to the «torn» and turbulent, created by the blades.
Good stability even of a floor-mounted bladeless fan, due to the absence of vibration created by the blades of classic models.
Possibility of smooth power adjustment.
Possibility of remote control of the device.
Easy maintenance and care.

Despite such impressive characteristics, the design of this climatic device was not without flaws. The main and rather significant disadvantage is the high level of noise generated by the device. The second, and probably the last drawback is the rather high cost of the device.

According to experts, household models have the greatest prospects because of their safety. It is hoped that engineers will eliminate the high noise level of bladeless fans, and the high demand for such models will force many manufacturers to refocus on their production, which will inevitably lead to lower prices.

I would like to start this review with one of the most popular devices among our compatriots, operating on the basis of the “air multiplier” technology, the Dyson Air Multiplier 01 fan. James Dyson.

Stylish bladeless desktop fan Dyson Air Multiplier 01

Dyson Air Multiplier 01 The device consumes extremely little energy, as it is driven by a turbine with a power of only 40 watts. The diameter of the air ring is only 30 cm. Despite this, the unit emits about 400 liters of air per second at full power. The height of the device is 50 cm.

At the bottom of the device there is a rheostatic type variable speed control knob that allows you to smoothly adjust the strength of the air stream. The Dyson Air Multiplier 01 is equipped with a frame tilt and lock, which makes it quite comfortable to use. The «air multiplier» is quite unpretentious and will not cause difficulties with cleaning and maintenance, therefore it will certainly attract the attention of the domestic consumer. The cost of the device in Moscow stores is about 235 USD.

Rotorless fan quattro elementi 771 398

Quattro elementi 771 398 Outwardly, it practically does not differ from the product of the British innovative engineer. The only external difference that can be seen is the diameter of the frame, which is 25 cm. Just like in the Dyson 01, an electric turbine with a power of 45 W sucks air through a grill in the lower part of the case, and throws it out of a slot of 1.3 mm. located around the perimeter of the ring. This quattro elementi 771 398 table fan is 5 cm taller than the prototype, which is 45 cm.

The quattro elementi 771 398 is equipped with a swivel system, rheostat air flow stepless adjustment and air ring angle adjustment. For ease of use, the device is equipped with a remote control. Unlike Dyson, the cost of this device was a pleasant surprise. In Russian stores, this installation can be purchased within 3300 — 4140 rubles.

Coolguy — small and stylish

The «invisible fan» coolguy is an excellent example of modern climate technology for home and office. This is what advertising says and the manufacturer himself positions his offspring. A small and stylish rotorless fan with an unusual design is made in a desktop version. Due to its small size, it will easily find a place on the desktop, which makes it useful for people who spend a lot of time at office work. But even at home, the coolguy can be a great helper thanks to the included wall mount. coolguy

In addition, the advantages of the device include:

Smooth adjustment of the force of the air jet.
Equipment of the device with the mode of automatic rotation by 45 °.
Adjustment and fixation of the angle of the frame.
Convenient remote control.
Equipping the installation with a timer for 60 and 120 minutes.
Low (in comparison with analogues) noise level, only 55 dB.
Profitability. The power of the device is 35 watts.

The cost of coolguy varies around 6 thousand rubles.

Fan hj 007 with a non-standard design for such equipment

Desktop version, but unlike all the presented devices, this fan has not the most “desktop” dimensions of 400mm x 300mm x 500mm.

hj 007 The main advantages of this device are: efficiency, turbine with a maximum air intake of up to 20 l / s; automatic 90° rotation function; the possibility of tilting the installation, smooth adjustment of the strength of the ejected air flow and simple control of three buttons.

Unlike the models presented above, the hj 007 fan has an LED indicator, which makes it possible to control the device even at night.

The disadvantages of the device include a small turbine drive power, which is only 24 watts. In addition, hj 007 cannot be attributed to budget models. The cost of the device today is 6,200 rubles.

Summing up

Based on a thorough study of customer reviews, technical specifications and cost-quality ratio, the Quattro elementi 771 398 rotorless fan was chosen as the most attractive model. even surpasses.

If you decide to purchase an «air multiplier» for home and office, do not pay attention to advertising slogans. All such devices work on the same principle, have similar functionality and a slight difference in power. First of all, pay attention to the noise level produced by the device and its cost.

Air conditioning with air flow from the street: the advantages of such climate technology

[ad_1]

Author Evgeny Aprelev Reading 4 min Views 5.9k.

In the conditions of modern airtight apartments, questions related to inefficiency are increasingly arising. [link_webnavoz][/link_webnavoz], namely with the lack of influx of street air masses. Due to the lack of fresh air in such rooms, the oxygen content in the air mixture is significantly reduced, which leads to a sharp decrease in the mental and physical activity of the people in it.

[contents]

Air intake from outside

Today, this problem is solved by creating a forced, equipping the premises with ventilators and wall inlet valves, as well as specialized climatic equipment — air conditioners with fresh air. In fairness, it should be said that it is more correct to call this equipment not with an inflow, but with an admixture of street air, and the volume of air masses supplied to the room usually does not exceed 40%.

The device and principle of operation of the air conditioner with inflow

with an influx of fresh air come in various designs. The most popular among our compatriots are models with a wall and channel arrangement of the indoor unit. The device of such climate systems is not much different from standard air conditioners, with the exception of the air duct that combines the indoor and outdoor units and the filtering system for the incoming air mixture. Channel air conditioners of this type are most often equipped with an electric or water heater, which heats the incoming air flow during the off-season. Air conditioning device with inflow

An air conditioner with forced ventilation mode for an apartment consists of:

Evaporative (internal) unit, which includes a heat exchanger, a fan, a filtration system, and an electronic control unit.
An outdoor unit including a compressor, a condenser heat exchanger, a cooling fan and an additional suction turbine, as well as a mixing chamber.

The mixing of air masses occurs as follows: by means of a suction fan, fresh air is supplied through the duct to the evaporation unit, where it enters a special chamber and mixes with the air from the room. After that, the air mixture passes through the filtration system and undergoes additional processing (heating, humidification, dehumidification, etc.), which depends on the version, the set mode and the model of the split system. Only after processing the air mixture is fed into the room. Microprocessor control allows you to automatically control the parameters of the air mixture specified by the user, as well as the strength of the air flow.

Scope and advantages of split systems of this type

Air conditioners with a function are most often used in residential sealed buildings equipped with modern metal-plastic windows, as well as in rooms with special requirements for air exchange and the quality of the air mixture.

Supply air filters

The main advantages of an air conditioner with an influx of fresh air are:

Year-round supply of serviced premises with an influx of fresh air. The competent approach of manufacturers made it possible to create such climate equipment that can work even at low temperatures.
High degree of purification of street air. An open window will give the necessary influx of air masses, but its quality, especially in a metropolis, leaves much to be desired. Split systems are equipped with efficient filter elements, thanks to which clean and fresh air enters the room.
Microprocessor control makes it possible to automatically maintain the set temperature and humidity characteristics and device performance.

Factors to pay attention to

Despite the rather serious advantages of such, air conditioners with forced ventilation for an apartment have not become particularly popular with our compatriots, and there are several explanations for this:

Increased noise level, the source of which is an additional fan. From Russia, the noise level is regulated by sanitary standards, which clearly state that the level of penetrating sound exposure to residential premises cannot be higher than 30 dB at night. Most of the common models of such climate technology have an indicator on the verge of this value.
A household air conditioner of this type cannot fully replace the ventilation system.
High price. The price of such a device is approximately 15-20% higher than that of inverter-controlled climate control equipment of similar power.

The choice of a split system of this type should be entrusted to professionals, since the implementation of proper air exchange and synchronization of the ventilation system with the air conditioning system is possible only with a competent calculation and assessment of the required volume of supply air.

Automatic ventilation for windows

[ad_1]

Author Evgeny Aprelev Reading 5 minutes Views 2.7k.

Plastic windows are convenient and inexpensive designs that most city apartment owners have installed for themselves. However, such products have their own characteristics, they have good tightness, which allows you to avoid drafts and heat leakage in winter, but at the same time this turns into a disadvantage — the room is not sufficiently ventilated.

[contents]

Stale air creates unpleasant sensations, so there is a need for ventilation. This problem is fairly easy to solve. In order not to waste time on airing, you can install an automatic climate valve on PVC windows, which will do all the necessary work.

Automatic ventilation device for plastic windows

Double-glazed windows with automatic ventilation — what is it? Usually, such a definition means windows equipped with valves with automatic ventilation control, which is carried out using special sensors that respond to external changes. Unlike manual devices, in this case you do not have to constantly worry about adjusting the ventilation.

All ventilation valves are divided into three categories that are on the market. There are many manufacturers that produce similar products for installation on window structures, so it is not difficult to purchase a device:

Slotted provide an adequate supply of fresh air. It enters through a special hole, which is covered from the outside with a special inlet valve. It protects against ingress of dust and insects from the street. In the room, the opening is covered by a regulating block. Such a valve is usually installed on the top of the structure or in a dividing profile, in a horizontal position. Its advantage is a sufficiently large throughput, in addition, this device does not require dismantling.
Seam valves are considered simple and inexpensive. They supply fresh air through small openings. Such devices allow for air flow without violating sound insulation, however, such openings will not be enough to ventilate large rooms.
Overhead valves have the highest throughput, providing good ventilation. However, the problem is that they must be installed at the stage of installation of the window structure, providing a separate place. You can not put such a valve when the window is already in use.

PVC windows with the possibility of ventilation provide an optimal indoor climate, which is important for the health of residents. The automatic system works by using pressure sensors or a hygrometer. They can react to the difference in pressure outside the window and in the room, or to the level of humidity, adjusting the ventilation process. You can also do this manually if the need arises.

It is not difficult to take care of ventilation valves, for this it is enough to clean them as they get dirty while washing windows. Usually this procedure is not required very often, so maintenance will not cause problems.

Tip: for optimal operation of the valve, it is necessary that the ventilation system in the room itself is in good working order. Otherwise, even if you purchase an expensive device from a well-known manufacturer, its installation will not give much effect. Therefore, you first need to make sure that everything is in order with the ventilation in the house.

Installation steps

Plastic windows with automatic ventilation allow you to get rid of stale air, as well as condensation on the windows. To do this, it is necessary to select and install a suitable valve. Automatic devices can be installed both on blind windows and on opening ones:

Installation can be carried out with the removal of the old double-glazed window and the order of a new one, with reduced dimensions. The valve itself is placed in the gap between the frame and the glass. The problem with this method is that the cost of installing and purchasing new glass increases.
Also, the valve can be installed in the place of binding, this option is suitable for sealed window structures. At the same time, the process itself does not take much time, about half an hour is enough to complete the work.
In addition, when ordering windows, you can also immediately take care of the installation of valves, indicating this when placing an order. Then, during installation, specialists will perform all the necessary work.

Advantages and disadvantages

Passive ventilation sensors on the windows are a convenient system that allows you to automatically adjust the process of fresh air intake. This option has a number of advantages that can be immediately noticed when using such products:

There is no need to constantly think about ventilation, the system itself will do everything necessary, reacting to changes in external indicators, and will take care of maintaining the optimal microclimate in the room.
If it suddenly seems that it has become too cold, then you can always close the ventilation valve manually, a similar possibility is also provided.
The use of valves allows you to extend the life of window structures, since they can deteriorate due to the accumulation of condensate that occurs in the absence of ventilation.
In addition, stale air, in which dust and unpleasant odors accumulate, is harmful to health, it can cause allergic reactions and diseases of the respiratory system, so ventilation is a necessary action.

Automatic ventilation device for windows

The disadvantages include the fact that the valves do not always provide sufficient ventilation if the room has a large area. In this case, you will have to think about purchasing an additional ventilation system. In addition, in some cases, the installation of the valve may require additional costs if the window pane needs to be replaced.

The winter set for the air conditioner allows the use of climate equipment at low temperatures, turning this device into a universal one. And how he does it, let’s try to figure it out now.

[contents]

Basically, the heating function in the air conditioner is practically not used, since there are strict limits for the operation of climate systems in the cold season. If the air temperature in the street has exceeded zero, then it is no longer recommended to use the device. Only a few manufacturers make their air conditioners in such a way that they can be used down to -7 ° C. Why is it so harmful to the modern split system?

Why You Shouldn’t Use Air Conditioning in Winter

In order to understand why it is impossible to use the air conditioner in the cold season, you need to remember its principle of operation: the compressor pumps freon into the condenser-heat exchanger where it is cooled. After that, it compresses the gas to a liquid state and delivers it to the evaporator, in which the capture of warm energy from the air during evaporation takes place. After that, this energy is transferred by gaseous freon back to the condenser, where it gives it to the surrounding air, cooling and passing into the liquid phase. Giving heat to the street air, the gas becomes cold and transfers this cold from the street to your home, giving the brought cold to the evaporator, and at the same time to the air blowing it.

When the climate system begins to work on space heating, the location of the condenser and evaporator is reversed using a device called a four-way valve. So why not use it in winter, many will ask.

Both the indoor unit and the outdoor unit can freeze. The fact is that the principle of operation of any split system is based on condensation and evaporation, on heating and cooling. What happens when cold metal meets warmer, moister air? That’s right, condensation forms, i.e. moisture, which simply freezes in cold air. When moisture appears in the air conditioner, it flows down the drain pipe outside the room. If this moisture freezes, and it will definitely freeze at temperatures below zero, then it will have nowhere to go and it will begin to seep through the pipeline connections into the device case, which will inevitably lead to its failure.

In addition, in the cold, the oil in the compressor freezes, which can lead to a stop or serious wear.
In conditions of cold air, freon will have nowhere to take heat to transfer it to the room, so the efficiency of air heating becomes almost zero.
Cold freon may not have time to move from the liquid phase to the gaseous one, and will enter the compressor, which can cause a water hammer and simply kill the compressor and the freon line.

How a winter kit can help

The winter kit for the split system includes:

A sensor that, at low temperatures, gives a command to the controller, slowing down the operation of the fan of the outdoor unit. This reduces the appearance of instrument icing.
Special compressor oil heater when the air conditioner is not running. This maintains little in the liquid state and enables an easy start of the equipment.
A device that heats the drainage pipeline, which saves it from freezing condensate and the formation of an ice plug.

Currently, some manufacturers produce the so-called low-temperature split systems, which are immediately equipped with equipment similar to the winter set. They can work perfectly for cooling the air in the room, up to the temperature «overboard» -25C °. It is for cooling, and not for heating, since everything in this world is subject to physical laws, and especially the law of thermodynamics. It is impossible to get heat from the cold without spending energy on it.

http://www.youtube.com/watch?v=MsR0gLum_dU We foresee indignant exclamations about what the winter set is for, and who will cool the apartment in winter! The thing is that the cooling of the room in the winter is not necessary for people, but for some mechanisms and such rooms in which a large amount of computer equipment is installed. In addition, cooling to certain temperatures is necessary in some laboratories and in certain technological cycles. It was for them that a winter air conditioner was invented, which can work for cooling even at sub-zero temperatures.

How to mount the «winter kit»

Accessories for installation in the air conditioner As a rule, such a set consists of three blocks:

Compressor oil heater.
A device that automatically adjusts the fan speed.
Device for heating the drainage pipeline.

Connecting these devices will not be difficult for a person who is versed in technology, because on each of them, for clarity, a connection diagram is drawn. So, after connecting the devices, and especially the fan speed controller, you need to check its operation, that is, apply voltage to the contacts. If the fan started spinning at full speed, and then slowed down according to the command of the temperature sensor, then the regulator is connected correctly.

Tip: If you are in dire need of air conditioning operation at sub-zero outdoor air temperatures and decide to install a winter kit, then contact the service department. And if you want to do at least something with your own hands to protect your split system, then purchase and install a visor for the air conditioner, which will protect it from the harmful effects of precipitation during the cold season.

Humidifier: choosing the best one for your home

[ad_1]

Author Evgeny Aprelev Reading 6 min Views 432

The normal functioning of our body directly depends not only on the liquid received with food, but also on the moisture in the air. After all, the optimal humidity for a person should be at least 40-70%. According to statistics, the moisture content in the air in our rooms often does not exceed 20%. In this connection, it turns out that a person does not receive almost 2/3 of the total amount of moisture. This, in turn, negatively affects the health of people, especially their children. Therefore, many of us have recently been wondering how to humidify the air in the room and achieve the optimal level of humidity. [contents] To solve this problem, mankind has created inventions that replenish the missing moisture and are called humidifiers.

In the general concept, an air humidifier is a device of a special type that can form the necessary or optimal level of moisture content in the air and the microclimate in various types of premises. According to their design, humidification systems are designed for direct operation in confined spaces.

Quite often, these devices do not require special installation and are quite convenient during operation. In addition, the optimal humidity in the apartment, created through the use of humidifiers, will get rid of many problems, for example, such as:

constant increased fatigue of residents;
the occurrence of damage to furniture (drying of wooden structures, paintings and musical instruments);
drying of the skin (feeling of tightness and peeling), which subsequently can lead to its rapid aging;
causeless wilting of indoor plants;
the appearance of the body’s susceptibility to the negative effects of pathogenic bacteria or viruses, due to the drying of the mucous surfaces of the respiratory tract and nasopharynx.

The main specific characteristics of humidification systems

Photo: Choosing the right humidifier Depending on the principle of operation, the following types of humidification systems are distinguished:

An ultrasonic humidifier is the most efficient type of device available today. They operate on the principle of supplying water to a vibrating plate with an ultrasonic frequency, due to which the liquid is distributed into a special fine suspension. In this case, the fan located in the device creates a flow supplied to the room. This type of machine allows you to create a kind of fog at home based on precise control of humidity, temperature of the outgoing steam, as well as a low degree of noise. In some cases, ultrasonic humidifiers can be equipped with a remote control system and various displays. The performance of such units can vary between 7-12 liters per day with an operating power of 40-50W;
steam humidifier — the mechanism of action of such units is based on the hot evaporation of a liquid and involves the usual boiling of water, due to which it is converted into steam and thereby the air is saturated with the necessary moisture. In general, the scheme of operation of the devices resembles the procedure for boiling water in an electric kettle. The design of the system itself assumes the safety of its operation. To maintain the optimal level of humidity in the premises, steam humidifiers are equipped with a special sensor — a hygrostat. To use these humidification systems for medical purposes, they are additionally equipped with inhaler nozzles. The performance of such devices can reach values of 7-16 liters per day with an average power of 300-600W;
air humidifier with an ionizer — a kind of climatic complexes that allow not only to increase the degree of air humidity, but also to additionally ionize and aromatize it. The design of such devices consists of complex hydrodynamic disks made of plastic and rotating in water tanks;
traditional air humidifier (or cold steam) — the principle of operation of these devices is based on the process of water evaporation in a natural way without the use of heating. In this case, water is placed in special tanks, from where it is fed into a bottom bowl, after which it falls directly on the evaporative elements, in the form of which discs, filters or cartridges can act. The simplest models work on the basis of the use of replaceable paper cartridges. In more expensive systems, the evaporator is presented in the form of rotating plastic discs that are constantly moistened. The performance of these types of humidifiers can be 3.5-8 liters per day at a power of 20-50W and, as a rule, depends very much on the level of humidity in the room, since the higher this indicator, the worse the evaporation process will be;
atomizers or spray humidifiers — are used only for industrial purposes, since they have a fairly high level of productivity, measured at 60-230 liters per day.

Depending on the basic direction of use, humidifiers can also be divided into several subgroups:

household air humidifiers — are used in ordinary living rooms in which adults live. This type includes ultrasonic, steam, as well as traditional systems that have a low noise level for the possibility of working at night and a sufficient volume of the tank to ensure continuous operation;
humidifier for home — a household device, often used in private houses or apartments to create a given level of humidity. At the same time, the normal air humidity in the apartment will directly depend on the chosen model and its overall efficiency, taking into account the general format and area of the room;
a humidifier for a children’s room is a special type of device that implies a high degree of safety, efficiency and silent operation parameters. Therefore, in order for the air humidity in the children’s room to be within the permissible and necessary values, it is necessary to use ultrasonic types, but not steam ones.

How to choose the right installation

Photo: Cost as a fundamental factor when choosing To correctly answer the question of which humidifier is better to purchase, you need to focus on three main components of the choice:

volume, area and shape of the room;
the conditions in which the installation will be carried out (children’s room, private house, apartment, office space, etc.);
the quality of the water that is added to the tank.

The fundamental factor when choosing a particular model of humidifier is its cost. The cheapest types are mechanical humidifiers, which include traditional and steam humidification systems. The second place in terms of price is occupied by ultrasonic systems, and humidifiers based on ionizers close this circle. In addition, within the same type, the cost of devices can vary significantly depending on their equipment with a control system (digital or analog), as well as additional features, such as a liquid crystal display, a hygrostat, the presence of a water heating function, etc. http:// www.youtube.com/watch?v=w4m2sBa0Dp4

To save your money, you can try to make a humidifier with your own hands. To do this, there are some not tricky methods:

arrange tanks filled with water around the room. In this case, the water will naturally evaporate and create the necessary level of humidity;
using improvised materials (a box and a cooler from a computer), arrange the structure as follows: a cooler from a computer is attached to the upper wall of the box and connected to a phone charger (regular power supply) to control the fan speed. At the same time, it is important that the air flow is directed from the cooler, and not vice versa. The evaporator can be a non-woven material placed on a metal structure, like a clothes dryer. For ease of use, a special marking of the water level can be applied to the box.

Thus, practically without spending a lot of effort, time and financial resources, anyone can independently create their own humidifier, which can effectively contribute to the organization and creation of a more comfortable and healthy microclimate for the room.

Purpose and device of a household window air conditioner

[ad_1]

Author Evgeny Aprelev Reading 5 minutes Views 3.1k.

Window air conditioner, despite some noise and obsolescence, is still a very popular climatic device in our country, and not only. In the USA, they have firmly occupied the niche of household climate control equipment, and to this day they win the rivalry with household split systems developed in Japan.

[contents]

Design features and difference from conventional split systems

«Window» is a monoblock, i.e. and compressor and evaporator are in the same metal case. The main «front» panel consists of plastic on which the blinds directing air flows, as well as levers and control buttons are located. Inside are the evaporator, condenser and two fans.

In addition to them, the device contains a freon pipeline, a throttling device, an electronics unit, an air filter and the «heart» of the entire device — a compressor. Depending on the functionality of the window window, additional filters can be installed in it. Many experts argue that the arrangement of devices resembles the device of a conventional household refrigerator.

The power of the air conditioner varies from 1 to 8 kW, and this is enough to maintain a comfortable air temperature in a large room. These devices are quite unpretentious, cheap and easy to do maintenance.

Working principle and scope

The principle of operation of window-type air conditioners is no different from monoblock mobile air conditioners.

The refrigerant after the condenser is in a liquid state.
With the help of a compressor, it is additionally compressed and fed into a throttling device to increase the pressure.
At room temperature and high pressure, the refrigerant enters the evaporator, where it boils and turns into a gas, while cold is released.
This cold takes away the air flow, which is created by one of the fans.
Gaseous freon passes through the filter element and enters the condenser, where again, at street temperature and atmospheric pressure, it turns into a liquid. Moving in a closed cycle, freon takes heat and releases cold to air currents, creating comfort in the room.

Contrary to the general opinion that the air conditioner creates cold, the principle of its operation is based precisely on the transfer of cold from the street to the room, even if it is +30 ° C outside. It follows that the main purpose of the «window» is not to create cold, but to create a comfortable microclimate in the room.

In addition to cooling the room on a hot summer day, this unit constructively reduces the humidity in the room. In some cases, this can be useful, and for rooms with dry air, it is worth considering arranging it with a humidifier.
Like most split systems, modern window air conditioners can not only cool, but also heat the air. They are called window monoblock air conditioners with cycle reversal function. This is a very useful feature in the off-season, when the central heating of the apartment is not yet working.
This type of climatic equipment is equipped with an air filter, which is designed to clean the air flow from mechanical impurities, dust, fluff, animal hair, hair, etc.

Installation is easy and simple

The name of the window monoblock, and in the common people «window» fully reflects the principle of its mounting — in the window opening, so when purchasing it, you need to pay attention to its size. The dimensions of window air conditioners should not be larger than the window opening at the intended installation site.

montaj_okonnogo_konditsionera Initially, a place for installation is cut out in the window opening. After that, the case is installed in the prepared space, and after the case is installed and fixed, the air conditioner itself is mounted in it. The space between the window opening and the body of the device is carefully foamed.

Such climatic equipment, with the wrong size of window openings, can also be mounted in a thin wall. If the wall thickness is not more than 30 cm, then you can make an opening in it, according to the size of the air conditioner, and install the device. This is what many owners of small trading pavilions do.

Advantages and disadvantages of «windows»

Pros and cons of window air conditioners Contrary to popular belief that this climate system is outdated and completely obsolete, and that it consists of only flaws, and the only advantage is the cold air emitted by it, is fundamentally wrong. The advantages of using them are not less than the disadvantages. Let’s start with the merits.

These devices are quite powerful, household windows have a power of up to 8 kW, which is no less than that of a solid household split system.
Window monoblocks are approximately 30-40% cheaper than a similar split system.
They are easy to maintain, and therefore the price of the service is somewhat lower than for other types of air conditioners.
Such climate technology is quite easy to install and practically does not take up space in the apartment.
These monoblocks do not have connections in the freon line, so there is practically no leakage in such units.
The service life and efficiency are much higher than that of split systems.
Another undoubted advantage is the influx of really fresh air. Only expensive split systems have such a function.

Advice:
Window conditioners differ in good maintainability. This fact can be attributed to the undoubted pluses.

But, like other types of climate technology, «windows» are not without drawbacks., Of which there are also many.

This type of air conditioner is one of the noisiest, as the compressor is located in the same housing as the evaporator.
Although this is a window type of climate technology, it is almost impossible to install it in stained-glass windows or metal-plastic windows.
This technique significantly reduces the luminous flux from the window. In addition, it cannot be covered with curtains or curtains.
One of the biggest disadvantages of using «windows» is that during its operation it is impossible to be near the device, since a cold cannot be avoided.

A window monoblock is not the most convenient option for air conditioning a home. But if you take a good look, then this type of climate technology has an optimal price-quality ratio. It can be used as a «mobile» air conditioner for summer residents. The choice is yours, the main thing is to take it seriously.

Modern supply ventilation on the balcony and insulated loggia

[ad_1]

Author Evgeny Aprelev Reading 4 min Views 3.4k.

With the advent of double-glazed windows and insulated windows made of PVC material, many owners are faced with the problem of condensation, which not only spoils the surrounding view, but also leads to mold on the profile itself. Many people remember that, according to the laws of physics, water droplets are formed when moist warm air hits a cold surface, and the greater the temperature difference, the greater the condensate. If a person is faced with such a problem, it must be solved as soon as possible.

Insulated balcony: «FOR» or «AGAINST»?

New insulation materials that can be found on the domestic market make it possible to well insulate your balcony or loggia, which is what many owners do. Few people think that any insulation always entails a deterioration in natural ventilation, so in this case, you should definitely think about creating such a system.

If the windows on the balcony are sweating, then it’s time to eliminate this negative factor. An ordinary open window is often not enough for a normal triple air exchange, so it is best to design a special supply ventilation.

The main problems of insulated balconies without ventilation:

Condensation on windows
The appearance of mold in the corners and joints of the ceiling, walls, floor
Musty smell in the room
Decreased performance of finishing materials
Deterioration of the appearance of the balcony

Today, each owner can solve this problem, because for this it is necessary to properly and competently organize the ventilation system. At first glance, everything seems simple, but in fact, this issue should be approached with all responsibility. In order for the ventilation on the balcony to be effective and efficient, it is necessary to clearly consider the entire structure, paying special attention to the area of u200bu200bthe loggia (balcony), as well as the power of supply and exhaust fans.

Balcony ventilation scheme

Air circulation during supply ventilation Many of our compatriots are quite capable of designing such a system on their own, for which you should purchase two fans of the same power, and then install them on an insulated balcony.

It is important to remember that, according to the laws of physics, humid warm air tends to leave the room, moving to the upper part of the room. That is why the fan for air intake from the street should be correctly positioned below, and the exhaust fan — in the upper part of the loggia.

Thus, the system in the course of its work is guaranteed to take all the moist air, driving it diagonally. Such ventilation is the most efficient and effective.

To complete the ventilation system, you will need the following elements:

Dry air intake fan from outside to inside
Ventilator for extracting moist air to the outside
Fastening systems
electrical wiring

Negative effects of insufficient ventilation

It is interesting to note that many people are thinking about how to make ventilation on the balcony, since stuffiness, stale air, mold and fungus are not only unpleasant for people, but are also harmful conditions for living. Inhaling the spores of such bacteria, a person can begin to suffer from various respiratory diseases, have muscle weakness, feel unwell, and have a headache.

In addition, products and seamings that are traditionally stored on the loggia can also become moldy, which will lead to their deterioration and the formation of an unpleasant plaque on the banks. That is why only the presence of a constant air circulation will reliably correct the situation.

Photo: Condensation may form in the upper part of the room Mold most often forms in the upper part of the room, since moist warm air always rises and, if it does not find a way out, then settles on the ceiling and walls. If you make heating inside the loggia, but do not insulate it outside, then droplets of condensate may appear even on the walls, which will lead to peeling of the plaster and deterioration of the type of finishing materials.

The fact is that in this case the “dew point” will be located indoors, which will lead to such disastrous consequences. To prevent this from happening, it is also important to insulate your balcony both outside and inside, which will smooth out the difference in temperature of the materials.

Proper ventilation is a guarantee of a healthy indoor climate

If mold does appear, then it must be removed as soon as possible, since it tends to spread quickly. To do this, use special solutions to remove the fungus, carefully treating the wall or ceiling with a brush or roller.

As a result of such simple actions, the mold on the balcony can be easily removed, but you need to remember that this is only a consequence. The main thing is to permanently remove the cause of the appearance of the fungus — stale air. Fans do a great job with this, so they can and should be used.

Summing up, we can say with confidence that supply ventilation in an insulated loggia will be the most correct solution that will allow you to quickly and permanently remove condensate from windows, mold from walls and ceilings, and adjust the temperature and humidity levels. So you need not to be lazy, but to implement a competent air venting system, which will bring qualitative advantages in all respects.
