Air curtain parameters

First of all, you should consider what the thermal curtain consists of. The design elements are:

• fan for air supply and circulation;
• heating element;
• temperature controller, which controls how warm the room is, prevents overheating of the heating element and melting of the structure;
• a filter through which air passes into the room;
• blinds;
• Remote Control;
• metal case (there are a large number of types of design, so you can choose the best option that is ideal for the interior of the room).

You should choose a design for yourself, based on the following parameters:

• Dimensions that must match the openings;
• The amount of air passed through the device;
• What temperature can the device pump;
• Noise that is created during the operation of the structure;
• Control method.

The size

The dimensions of the thermal curtain are determined based on the width of the doorway. It is best to choose a device that will be placed across the entire width of the opening or slightly exceed it. There are models ranging in size from 60 centimeters to 2 meters. Most often, thermal curtains with sizes from 80 centimeters to 1 meter are popular. These models are considered standard. If the room has a doorway height of no more than 3.54 meters, then in this case it is possible to choose a thermal curtain in size. For openings, the width of which significantly exceeds two meters, several devices are installed at once, while they are attached tightly to each other.

Performance

Air curtain performance is a parameter that shows how much air is pumped by the device in a certain time.

The power of the structure indicates the speed of the air flow that comes out of it. It depends on this indicator at what height you need to install the device. The most optimal speed is considered to be 2 meters per second directly at the floor itself. If this condition is not met, then a gap will form between the floor and the curtain, which will allow the circulation of cold and warm air flows from room to room. Thus, it will not fully warm up.

The power of the heater depends on the purpose of using the thermal curtain. In order to heat a room of 10 square meters that is not heated, it is necessary to spend at least 1 kilowatt per hour

But it should be taken into account that in most cases the air curtain is not used as the main source of heat. If you put the device for this purpose, you will need high power, this will lead to a large waste of energy and, accordingly, will affect the budget

Noise level

It is very important for each consumer to know the noise level of the structure installed in the room. The same indicator is important when installing a thermal curtain.

The most optimal for offices and residential premises is the emitted noise of 60 dB. Models of a thermal veil work almost silently. The level they emit barely reaches 44 dB. To understand how loud it sounds, you should compare it with ordinary human speech. The noise level in this case reaches 45 dB.

Control methods

You can control the structure using a remote or built-in remote control.The curtain itself is activated by two elements. In the first case, the fan turns on and off, in the second case, the heater.

The built-in remote control is most often used in small air curtains that meet the standards. Remote - used only on structures that are installed in production. In this case, it is installed where there will be the most convenient access to it.

Connection methods

Connect thermal curtains, depending on the power of the device. Small installations with low power can be powered from a conventional single-phase outlet. More powerful curtains need to be powered from a three-phase network. Therefore, when buying a product, you need to specify how exactly you need to connect the device.

What you need to know about thermal curtains

A thermal curtain is a technical device that prevents cold air from entering the interior. It is usually installed at the entrance to a building with a large flow of visitors, as well as with an intensive turnover of imported or exported goods.

Such devices can be found at the entrance doors:

• supermarkets;
• administrative buildings;
• hotels;
• medical and educational institutions;
• stations;
• metro stations;
• production shops;
• warehouses and hangars.

Inside the body of the air curtain there is a heat source and a powerful fan that creates a directed air jet. In the zone of action of such an apparatus, an area of ​​\u200b\u200bhigh pressure is created, which in the cold season does not allow air from the street to penetrate into the building, and warm from the interior - to freely go outside.

Working principle of thermal veils.

Often such equipment is included in the summer. In this case, it does not allow outside warm air, exhaust gases from automobile engines, dust and insects to enter the conditioned microclimate zone. Thermal curtains help to get rid of drafts, which saves the cost of operating air conditioners and heating appliances. It is believed that with their help, energy losses through doorways are reduced by 70%.

Varieties of thermal curtains depending on the installation location

Thermal curtains are always located in the immediate vicinity of the doorway. According to the installation site, several types of devices are distinguished.

Horizontal curtains are mounted directly above the doors, and the jets of air coming from them hit from top to bottom.

Vertical curtains are installed on the side. There may be one or two. This directly depends on the width of the door and the power of the fan. The height of the devices must cover at least ¾ of the opening.

Column curtains are stand-alone racks at the entrance. They are used singly or in pairs. The air from them is directed horizontally, cutting off the exit from the rest of the room.

Ceiling curtains are usually built into suspended ceiling elements. They are almost invisible. The visitor sees only the air duct gratings, inscribed in the overall design of the room. For this, such equipment is often called hidden-installation thermal appliances.

Electric or water curtains

The heat emitted by the air curtain can be transferred in different ways. Sometimes there is equipment with gas heating, but it should be classified as exotic. In our opinion, two main types of veils deserve mention:

Electric air curtains

Inside such devices there is a heating element connected to a 220 or 380 volt network. Devices in this category are compact, easy to install, easy to operate and maintain. Modern models are equipped with a heating power switch, adjustable airflow intensity, a timer and an air temperature controller.

Water thermal curtains

Inside they have a built-in tubular heat exchanger, through which the coolant is passed from the central heating network or from an individual boiler that heats the building. They have large dimensions and are quite difficult to connect. They have two main advantages: high power and economical operation. Such devices are often installed at enterprises near entrance gates or large doorways.

Type of heating element: heating element or spiral

The electric heating element can be a high resistance refractory alloy coil or a tubular heating element. The first option is slightly more efficient in terms of heat transfer due to the high surface temperature of the wire. But there is a downside to the coin, which is the relatively short life of the heater.

TEN is considered a more advanced device. It is also equipped with a spiral, but it is placed in a sealed tube, the free space of which is filled with quartz sand that conducts heat well. Its outer surface is smooth or ribbed.This design has a long working life and excellent heat transfer properties.

Types of devices by the presence and type of heat exchanger

How to choose a thermal curtain and what to pay attention to - these are the questions that a potential buyer faces when a decision is made on the need to install such equipment. Among the selection criteria, an important indicator is the type of thermal energy source, through which air flows are heated.

Models with electric heat exchanger

An electric air-thermal curtain is a device in which air is heated when it passes through an electric heating element (heater, spiral, stitch elements). This type of installation has a number of advantages compared to other analogues:

• ease of installation and maintenance;
• the absence of a complex design of the heat exchanger determines the low weight and variety of forms of the device body;
• for inclusion in the work, it is sufficient to have only a point of connection to electrical networks, without laying other engineering networks (heating, hot water supply, etc.).

A household thermal curtain on the front door, equipped with electric heating elements, is connected to a 220-volt electrical network

The disadvantages of air curtains equipped with an electric heat exchanger are:

• increase in the installed capacity of the consumption object as a whole and, accordingly, the cost of paying bills for the consumed electrical energy;
• the need to lay additional electrical groups designed specifically for connecting a thermal curtain.

Models with water heat exchanger

A water thermal curtain on the front door is another type of device of this type, the distinguishing feature of which is a heat exchanger made in the form of a water heater. This type of installation is used, as a rule, in public, administrative and industrial buildings, due to the design of the heat exchanger and the need to connect to the heating circuit of the building (structure).

Thermal water curtain "Ballu W2"

This type of curtain is connected to the central heating system, and the coolant circulating through the heater transfers its thermal energy to the air that also passes through it. The advantages of units of this type are the following indicators:

• efficiency in terms of electrical energy consumption, tk. it is used only for fan operation;
• the possibility of using on openings with large overall dimensions;
• significant power.

The disadvantages include:

• the complexity of the installation work;
• high price;
• the need for automation systems that ensure operation in various modes of use, preventing freezing of the coolant.

Models not equipped with a heat exchanger

Manufacturers produce air curtains in various configurations, corresponding to the declared specification of the consumer, standard configuration or without a heat exchanger. These can be conventional models that do not have electric heating elements or a heater. In this case, the air curtain operates as a simple fan with narrow air distribution.

How to connect correctly

The connection of the thermal curtain is carried out through a separate machine on the electrical distribution board. For installation, a three-core copper cable with a cross section of 1 sq. Mm is used. Additionally, fuses are included in the circuit, the selection of which is carried out taking into account the peculiarities of the operation of the local power grid.

Ballu is one of the most popular manufacturers of thermal curtains

The connection to the electrical network of thermal curtains from the manufacturer Ballu is carried out according to the general rules discussed above with some nuances:

• the selection of the circuit breaker and the power cable going from it to the installation is carried out taking into account the parameters recommended by the instructions;
• taking into account the power consumption, the connection is carried out either from a single-phase power supply at 220V, or from a three-phase power supply at 380V;
• the control panel is mounted outside the air flow zone of the curtain in order to exclude the dependence of the thermostat on the temperature of the air masses directed through the nozzle.

Teplomash devices are equipped with remote control panels. Their connection to the current source is carried out in compliance with the following nuances:

• power supply network with a voltage of 380V;
• the control cable is laid using the "hidden wiring" method.

Thus, by choosing a thermal curtain according to a number of different parameters that are typical for a room requiring a protective shield, you can forget about drafts, unpleasant odors and annoying insects. Installation of equipment is available to anyone, and to connect the device to the mains, you should use the service of a specialist with the appropriate access group.

Thermal curtains have long been used to regulate the microclimate by protecting and distributing temperature zones in rooms for various purposes.The principle of operation of this equipment provides the possibility of combining such operational qualities as energy saving, performance and functionality. That is, at low cost, a standard air-thermal curtain can perform part of the functions of an air conditioning unit and a heating system. It remains only to correctly install the unit and subsequently properly maintain it.

Design and principle of operation

The air-thermal curtain is a simple heating device resembling a fan heater in its design. Their main purpose is to create an invisible air thermal barrier for cold air penetrating into the premises through the entrance openings. To do this, they are equipped with powerful heating elements or water heating elements that provide heating of air masses.

The creation of air pressure in thermal curtains for entrance doors is carried out by small-sized tangential fans equipped with multiple blades.Their task is to direct the flow down, creating a kind of barrier to the cold. The pressure is selected in such a way as to ensure a flow velocity near the floors of at least 2.5 m/s. Only in this case, you can count on maximum efficiency.

A thermal air curtain above the front door drives the heated air down, gradually warming up the space in the room and helping the main heating. When the door is opened, cold air partially enters the room, which mixes with the heated masses. Nothing prevents leaving the door open - if the performance is selected in accordance with the recommendations, the cold will have practically no chance to enter the building.

The exception is powerful gusts of wind, which relatively easily blow away jets of heated air escaping from the thermal curtain.

Thermal curtains protect not only from the cold, but also from the burning summer heat, which is especially important in the southern regions. Here, fierce heat can penetrate through the entrance doors, the salvation from which is not only air conditioners, but also invisible air barriers. To do this, some air curtains are equipped with a fan function.

The thermal curtain for the entrance door consists of the following units and parts:

In addition to its main function - cutting off cold air - a thermal curtain is capable of a lot more.

• Heating element - water or electric, provides heat generation;
• Fan - drives warm air into the working area;
• Control system - controls the temperature and controls the on / off of the device;
• Housing - protects the inside of the equipment from access by unauthorized persons.

Control modules are often located outside the housings - in the form of separate thermostats with controls. Also in stores you can buy models with remote controls. Let's see how thermal curtains for openings differ from each other.

Classification

By installation type

Depending on the mounting method, thermal curtains are vertical (side), horizontal, and also universal. Horizontal models are fixed immediately above the door. The vertical heater is fixed on the side: it can be located on one side of the opening or on both sides at the same time, while the installation height should be approximately 3⁄4 of the total height of the opening.

Universal models allow installation in both vertical and horizontal directions. This design is by far the most popular. Depending on the method of installation, it is possible to distinguish between built-in and suspended structures.

By type of coolant

Depending on the type of heat exchanger, air curtains are water and electric, there are also products in which a heat exchanger is not provided. The most widely used air electrical devices operating from a standard 220 V network. Such installations have increased efficiency parameters, in addition, they are distinguished by ease of installation and the ability to gently regulate the heating of the air mass. The only drawback of such installations is the high consumption of energy resources associated with maintaining the operation of the fan and warming up the heat exchanger. In addition, such installations at startup have some inertia, that is, it takes some time to enter a full-fledged operating mode.

Thermal curtains operating on heated water are connected to the centralized water supply and heating system in private housing construction. The advantage of the equipment is considered to be the minimum cost of maintenance and operation of the equipment: the electricity here is spent solely on maintaining the operation of the fan, as well as the functioning of the control unit. At the same time, it was not without drawbacks - such an air curtain has many difficulties during installation, here it is necessary to additionally mount pipes, embed control valves, and also install stop valves.

When installing a water-type heater, it is very important to foresee a branch circuit from the main circuit in advance - this is often difficult to do in a situation where the heating system is already fully equipped. For a tubular heat exchanger, it is necessary to provide a special filter device that will prevent overgrowth. When buying such a curtain, it is necessary to take into account the total power of the installation, it must fully correspond to the operating capabilities of the heating system, otherwise the work will affect the degree of heating of the radiators in the house
