The thermal curtain was invented in North America in 1904. True, the first such device was released only in 1916.
Presumably, at first, thermal curtains were used only for heating vestibules, but in the 1950s, demand skyrocketed, giving this equipment wide distribution throughout Europe.
Thermal curtains came to our country en masse only in the 1990s.
A thermal curtain (air, air-thermal curtain) is a rectangular fan heater that is installed in a door or gate opening and creates a powerful air flow (often heated). The main purpose of the air curtain is to maintain the set temperature in the room, which is achieved by cutting off cold air from the outside with a flat air jet under pressure.
Air curtains are of two types: cut-off (shielding) separate zones with different temperatures and humidity, creating an air barrier along the entire length of the opening. Thermal curtains mixing type additionally heat indoor air during the cold season, prevent drafts, help reduce heating and air conditioning costs, and prevent insects and foreign odors from penetrating from the street.
A thermal curtain separates the air inside the room from mixing with the outside atmosphere with a jet of air.

Five Unique Benefits
one
The thermal curtain stabilizes the temperature in the room during the cold season, and also protects against the ingress of insects, dust and exhaust gases. A complete list of functions is indicated in the instructions for a specific air curtain. View or download instructions for heaters.

Due to lower heat losses when using a thermal curtain, heating costs are significantly reduced. Savings can be up to 30%. In the section of promotions for heating, there are often special offers for energy-efficient thermal curtains at a discount.

With a thermal curtain, the front door can always be kept open, which is important in many areas of business. Therefore, a thermal curtain is installed at public catering points, car services and car washes, at walk-through offices.

Under the ceiling, the air is always warmer than at the height of human growth. This ratio is called the temperature gradient. The warm flow from the curtain equalizes the temperature difference and makes the area where people are more comfortable.

The air curtain neutralizes drafts in the room. It is drafts that are considered the main causes of colds and viral diseases. This and other features of air curtains are discussed in the appropriate «thread» of the HVAC professional community.?.

Water/Electricity: How is choosing a veil similar to choosing a Pokémon?
Like Pokémon, thermal curtains come in water and electric.
According to the heating function, air curtains with a heating function (air curtains) and curtains without heating (simply air curtains) are distinguished.
According to the purpose and application, household (mixing type) or industrial (sliding type) air curtains are distinguished.
According to the type of installation, horizontal and vertical models are distinguished, but most curtains are universal.
According to the type of heat source, the curtains are divided into:
-
electrical (heater, spiral, etc.). The most common and affordable models of thermal curtains. Of the benefits — simple installation and a wide range of models and manufacturers. Of the minuses — the cost of electricity;
-
water. The heat source is hot water. They are economical compared to electric curtains, they are distinguished by high power, however, the cost of equipment is higher, and installation is much more difficult;
-
gas. They run on natural gas, which is one of the cheapest types of fuel. Of the minuses — the equipment itself costs a lot.
-
without heat source. They are most often used in refrigerators and freezers to protect openings or to delimit large rooms into zones with different temperature conditions.
There are many classifications of air curtains. This is one of them.
Do I need to adjust for global warming when choosing a curtain?
The most important characteristic of air curtains is performance or air flow.
When choosing a thermal curtain, you need to understand how power differs from performance, what are the parameters of the room and the doorway, what are the weather conditions outside (hello, global warming 🙂 ), which thermal curtain is more relevant for you — water or electric, which automation is preferable.
The main characteristic of an air curtain is performance, that is, the efficiency of cutting off air from the outside from the air inside. Also, when choosing a curtain, it is reasonable to rely on the following criteria:
-
room type
-
the presence of a vestibule, the natural environment outside the window
-
purpose and power of the air curtain
-
length of the effective part of the equipment (dimensions)
-
optimal installation method (vertical/horizontal, concealed)
-
air capacity (air flow characteristics)
-
energy source (water, electric)
-
type of heating element (spiral or heating element)
-
equipment power

And, of course, how to avoid them.
Who better to cope with the calculation of the veil
The power of the air curtain is calculated, if very roughly, as follows: at least 0.1 kW per 1 m² of an unheated room with minimal thermal insulation.
When choosing a thermal air curtain✎ make calculations based on the questionnaire. It is better to entrust it to professionals. Especially when it comes to cut-off curtains (shield type) — too many parameters should be taken into account in this case.
Calculations for the performance of mixing type air curtains (m³/h):

OPINION OF A PROFESSIONAL
