What is a supply ventilation system?

A feature of many modern premises is excessive sealing. This occurs due to plastic windows, doors with several sealing contours, interpanel grouting. All this contributes to protection from noise and dust, but deprives users of fresh air. To correct the situation, a forced supply of outside air is necessary, which does not reduce the insulating properties of the housing. All this is implemented in the supply ventilation system.

The supply ventilation system is a set of devices in one or more housings to ensure the supply of outdoor air into the premises. In addition, the flow is heated, cleaned or cooled.

The supply ventilation system consists of the following units:

• filter at the inlet, which ensures the retention of dust, harmful gases;
• a fan that promotes the forced movement of air masses from the street into the rooms;
• heater to ensure a comfortable temperature of the incoming air;
• noise absorption system isolating sounds from other parts of the equipment;
• automation that protects the nodes from overheating and monitors compliance with the specified settings.

The type of equipment and dimensions depend on the area of ​​​​the premises and the number of people permanently staying in them. There are small models the size of a case, and there are also huge cameras that occupy entire rooms in the attic.

Another supply ventilation can be monoblock or duct.

The first is designed to supply air to one room, directly at the installation site. Differs in simple installation, the compact sizes. Most often installed on the balcony or hung on the wall as an air conditioner. But each room needs its own block, which is costly with numerous rooms.

Duct design implies a developed network of channels throughout the building, where fresh air is supplied from one main unit. It is more difficult to install, but more efficient and cheaper to maintain. For an apartment with an area 40-50 m2 enough model with performance 200-350 m3 per hour.

What is a ventilation system for?

A modern supply ventilation system is much more efficient than conventional fans mounted in a window. It is designed to implement several tasks at once:

• forced supply of fresh air to the premises;
• purification of air streams from dust and pollen, unpleasant odors;
• heating of the incoming mass to a level of at least 18 degrees;
• creation of air curtains from harmful gases;
• facilitating an increase in internal air pressure to displace the exhaust air through the outlet channels.

Depending on the equipment, the equipment is able to cool the incoming fresh air, providing a comfortable microclimate. Supply ventilation can work even in severe frosts, heating the flow and reducing heating costs (with a heating element or with a recuperation function). Installations can be used in apartments, offices, industrial premises, shopping centers.

What are the benefits of forced ventilation?

• Unlike natural ventilation, supply ventilation does not require manual control (opening windows, doors). Everything happens in automatic mode, set by the settings.
• The use of forced ventilation does not depend on the time of year, the weather outside.
• The set temperature is maintained with forced heating or cooling, depending on the capabilities of the equipment.
• The incoming air passes through several filters (coal, pleated);
• Suitable for rooms of various sizes from children’s bedrooms to production workshops.
• There are many options for implementation both in terms of cost and appearance, which is optimal for the budget and interior design.
• When using models with a recuperator, energy resources are saved.

When choosing a supply ventilation system, we can suggest how to correctly calculate its performance and what form of design and equipment will be more practical in a particular situation.
