What is a thermal curtain

In order to protect against the penetration of cold air masses into the room, systems called thermal curtains were developed. Installed in window and door openings, the most vulnerable places in any type of room, the devices create a directed flow of warm (heated) air, evenly distributed over the area of ​​the openings. The created air barrier prevents the penetration of cold air masses and at the same time prevents warm air from escaping.

What is a thermal curtain

The design of the devices may differ, but the principle of operation is the same for all models. The air is pumped by a fan and, passing through a set of heating elements, is directed into a distribution system made in the form of a large number of nozzles or in the form of blinds, which regulates the direction and intensity of air flows. Both nozzles and louvres are designed to direct air flow at an optimal angle (up to 40 degrees).

To create a uniform air flow, a special type of radial fan (turbine) is used. It is located inside the body along its entire length. Maximum length 800 mm. Therefore, when arranging wide openings, several engines are used, each of which is associated with a separate turbine, or one high-power engine that provides torque to two turbines located on different sides of it.Rotation speed, regulation of flow sections of intake and distribution openings, heating temperature, operating mode can be set manually or automatically. Most modern designs have electronic control systems.

Standard electric heating elements are most often used as heating elements. Depending on the power, they are able to intensely heat the passing air flow to create a dense curtain. The disadvantage of such heating elements is high energy consumption. Infrared heating elements are used mainly in large shopping centers and industrial facilities. They are also becoming widespread when installing equipment in individual buildings. The high cost of such elements is quite an expensive expense item for use in small facilities (workshops, shops).

Another type of heating element, a heat exchanger with circulating hot water, has lower heating efficiency and, accordingly, the performance of such equipment is lower when compared with electric and infrared elements. But having constant access to the central water supply system or to separate boiler rooms, the costs when using thermal curtains with a water heat exchanger will be significantly lower.

REFERENCE! All modern thermal curtain systems are capable of functioning in ventilation and air conditioning mode, being one of the options for climate control equipment for industrial and domestic use.

Types of thermal curtains

There are three main types of thermal curtains:

• horizontal;
• vertical;
• built-in

Horizontal

This design is installed above window and door openings. The flow of warm air is directed from top to bottom.They are distinguished by reliability and practicality. Positive qualities include high performance and uniform distribution of warm air flow.

Vertical

This design involves installing the air duct distribution system in a vertical position, on the side of a window or door opening. This system is optimal when there are narrow and high windows and doors. In this case, warm air masses do not deviate in the opening area and ensure reliable cutting off of cold air from the outside.

Built-in

A similar system is most often used in rooms where suspended or suspended ceilings are initially installed or are expected to be installed. In principle, such a thermal curtain does not so much play the role of a barrier to the penetration of cold air, but rather acts as a climate control equipment. A continuous supply of warm air flow ensures comfortable climatic conditions indoors and is guaranteed to eliminate possible drafts.

Scope of application of thermal curtains

Modern thermal curtains are used in places where warm air is consumed quite intensively, for example, doors are often opened and closed or there is a need to keep them constantly open.

REFERENCE! In many retail outlets, you can see doors that are constantly open. According to research by marketers, sales levels increase in stores where the entrance is open. The statement is controversial, but the use of thermal curtains in this situation is practically the only way to maintain an acceptable temperature indoors.

Industrial workshops, warehouses, public buildings, metro.In any of these facilities, the use of thermal curtain systems only increases the overall level of comfort inside. Small trade pavilions and even individual trade tents are equipped with thermal curtains.

These systems have also become widespread in everyday life. Equipped with a system for protecting against the penetration of cold air, the garage allows you to stay inside for a long time, even with the doors open. Cottages with this type of equipment have an additional opportunity for comfortable living and pastime.

A thermal curtain system correctly selected according to technical characteristics and installed in accordance with the necessary requirements and recommendations will provide reliable additional protection from the cold.
