Installation of a thermal curtain from start to finish. How to choose the right thermal curtain? How to install a thermal curtain

A thermal curtain is a climate equipment, which is a type of space heating. The device, design, characteristics of such devices are different, but all devices have a single principle of operation. The process of connecting and selecting an air curtain requires special attention, as safe and efficient operation depends on it.

1 Design and purpose of the thermal curtain

To regulate the microclimate, a device such as a thermal curtain is often used. This equipment is a powerful fan heater, which is located in metal case, often having a rectangular elongated shape.

The thermal curtain is installed above the front door and does not spoil the interior

The design of the equipment contains the following elements:

The device is easily mounted on the wall and provides a flow of warm air

The thermal curtain is designed to regulate the microclimate and distribute temperature zones in different rooms. Often the equipment is installed above the entrance from the inside of the room, which allows you to protect the space from cold streams and provide a comfortable temperature. This solution is optimal for a private house, shop, shopping centers and any other buildings where Entrance door often opens and enters through it cold air. At the same time, safety requirements prohibit the installation of air curtains in rooms with flammable materials, in transport, mines, automated production facilities.

Operating principle

The simple principle of operation of the air curtain is ensured thanks to the well-thought-out design of the device. A powerful fan draws in air from outside, after which the masses pass through the filter and are cleaned of dust. Further, the air moves through the area of ​​​​the electric heated coil, the temperature of the flow rises and it enters the room through the nozzles. The direction of the jet can be vertical or horizontal.

The air entering the room is cleaned of dirt, heated and enters the room

The distribution and amplification of the flow of warm air is due to the fan. The power and speed of the equipment may be different, and functional models have buttons and switches that allow you to configure the operation parameters.

2 Air curtain options

The range of thermal curtains includes several types of devices that differ in design and appearance, location. Electric models are in demand and practical in operation, but consume a large number of electricity to heat the air. Heating element in such devices - electrospiral.

Electric models are easy to use but not economical

There is also a water type in which there is a heater. This element withstands extremes and low temperatures, which ensures the reliability of the equipment. The device is connected to the central hot water supply, as a result of which the installation and construction cost are higher than that of electric options.

Water models are difficult to install and have a high cost.

These options are the main and most popular for providing heat at the entrance to the room. The dimensions and power of the devices are presented in various options, which allows you to choose the optimal equipment depending on the parameters of the opening, the air temperature outside and the desired level of heating inside the room.

3 Preparing to install tools and materials

Before installing the device, it must be taken into account that the air curtain must correspond to the width (if placed horizontally above the door) or the height of the opening (if installed vertically on the sides of the opening). To do this, you need to select equipment of the appropriate length or install several devices in a row. The easiest installation electric model, and for work you will need the following materials and tools:

Pendulum pendants are required for ceiling mounting.

When purchasing brackets or hangers for fixing, you need to take into account the weight of the equipment. Such parts may be included with the device, but you can pick them up separately.

4 Options for placing thermal curtains

For openings less than 1.5 m wide, horizontal placement is optimal, which involves mounting the device above the entrance to the room. In this case, the curtain can be installed on the ceiling or above the door. Thus, the device can be fixed close to the wall or suspended. There are other options for placing the curtain, each of which has certain features.

The curtain must be equal to the width or height of the opening

Horizontal mount

Horizontal fixation can be carried out on the ceiling or on the wall above the opening, as mentioned above. The second option is most in demand, as it allows you to more effectively prevent cold air from entering the room than when installed on the ceiling. In this case, the air flow will be directed from top to bottom.

Horizontal mount well protects from the cold

For installation, perform the following basic steps:

Detailed instructions, taking into account the individual characteristics of the device, are supplied with the thermal curtain. Therefore, before installation, you should study the instructions from the manufacturer.

Vertical installation of a thermal curtain

The placement of devices on the sides of the opening to its entire height is vertical method installation of thermal curtains. This technology is optimal if the horizontal method does not allow covering the entire area of ​​the opening with a warm air flow, as well as with an entrance width of more than 2 m.

Vertical placement requires more devices than horizontal placement

Installation is carried out according to the instructions, but the main stages of work are expressed as follows:

Installation of elements vertically is carried out according to the same technology as horizontally. In this case, the cases are fixed on both sides of the opening, which will ensure good protection by cold.

5 Connection Features

Modern equipment has a flexible cable and a plug that provides connection to the mains through a socket. If a stationary installation is carried out, then it is possible to connect the air curtain through a central type switch, which has an air gap and a parameter of 3 mm. This connection option is always carried out by an electrician.

Installation can be done independently, but the connection is carried out by the master

The scheme for connecting thermal equipment to the central switch is developed individually. It is simple to connect one device, and for this, two wires from the air curtain are connected to the corresponding network cables, taking into account the location of the “zero” and “phase” wires. For safety, an RCD block is added to the chain, capable of shutting down the system in an emergency. The housing and all power parts must be grounded.

Connecting air curtains from different manufacturers

The most famous manufacturers of climate control equipment are Teplomash and Ballu. Each manufacturer in the kit for the equipment provides detailed instructions for connection and installation, but the main features can be considered separately.

Ballu brand produces a variety of models of thermal devices

Features of connecting and operating Ballu equipment are expressed as follows:

Teplomash devices have simple design and affordable

The device of Teplomash firm assumes control of veils from the portable or remote control. Degree of protection of a cover of the control panel - IP20. When controlling the air curtain from the remote control, it is necessary to observe the distance to the infrared receiver on the remote control up to 6 m and the angle up to 60°. The air curtains are connected to the network through an automatic switch and a residual current device (RCD). RCD actuation current - 100 mA. The air curtains are powered from a three-phase electrical network with a voltage of 380 V/50 Hz. The control panel involves connecting the control cable 7x0.5 mm using the " concealed wiring". If it is necessary to bring the cable with “external wiring”, then it is necessary to make a recess of 50x10mm in the wall at the point where the wire exits from the console case.

Selection, installation and connection of thermal curtains from different manufacturers require the following general rules, including taking into account the required functionality and device parameters. Correct further operation will ensure the safety of equipment.

The installation of a thermal curtain, which is considered the most effective type of equipment to reduce heat loss, will help prevent the entry of cold air masses through opening doorways.

Installations of this class are mainly mounted in rooms with high traffic, but they showed no less efficiency when placed above windows, for example, in cash desks, small shopping pavilions.

General questions about installing thermal curtains

One of the main advice of experts is that the installation of a thermal curtain should be carried out only by a professional who knows all the intricacies of the formation of different-temperature air flows, who is able to assess the technical capabilities of the equipment. Of course, this will entail an increase in the cost of the device, but it will provide a guarantee and maintenance of thermal curtains.

If we consider the process of installing a thermal curtain as a whole, then first of all it is necessary to pay attention to the following points:

1. mount thermal curtain it is necessary as close as possible to the plane of the opening, while it is necessary to achieve its complete overlap with the created air flow.
2. Installation air curtains performed only from the inside. External mounting is allowed only if the possibility of overheating or defrosting of the refrigeration (refrigeration) chambers is prevented.
3. Before putting the air curtain into operation, it is necessary to adjust the ventilation and air conditioning system of the building. Such a mode of operation of these systems should be chosen in order to minimize the impact on the air flows created by the curtain.

Only the brackets offered by the manufacturer should be used to fasten the installation elements. For installation, anchors are also used that can withstand not only the weight of the air curtain units, but also the possible vibration load.

Ways to install thermal curtains

Depending on the curtain model, vertical or horizontal scheme installation (there are also universal models that can be mounted in both positions).

• Thermal air curtain for vertical installation most often used to protect high, narrow openings. Under such conditions, only a very powerful horizontal curtain can be provided to create a flow that completely blocks the passage section. Therefore, the use of vertical mounting is a cost-effective option.

Installation is carried out from one of the sides of the opening, while the distance from the wall must be at least 30 cm.

• Horizontal mounting much more common today. In this case, the air curtain is mounted above the window (door) opening. When choosing a device, make sure that it work zone matched or slightly exceeded the width of the door.

Quite often, all curtain units are installed in the structure. false ceiling, only the grilles of the air intakes and air ducts remain visible. This method is attractive not only from a design point of view, hidden installation can somewhat reduce the level of noise generated during operation of the installation.

When choosing horizontal air curtains, remember that each model has a certain maximum working height. Most of the units are able to effectively protect doors up to 3.5-4 meters high, and installations for extra-large transport gates (up to 15 meters high) are most often produced with individual development project.

Installation of thermal curtains

Before you install a thermal curtain, you must carefully study all the documentation attached to it.

During installation, it is necessary to ensure the separation of incoming and outgoing air flows. Failure to do so may result in reduced performance of the device.

Connection of thermal curtains

In practice, units with an electric or water heater are used, the connection of a thermal curtain in this case is significantly different.

It is more simple in technical terms to connect electric thermal curtains. One of the few conditions is the presence of a separate power supply line with an appropriate cross section (the cable must withstand continuous operation at maximum load). In addition, professionals recommend laying a backup power line, this will help prevent possible problems in future.

In addition, it is necessary to have protective earth air curtain housing and all power electrical elements. Most systems are equipped with systems automatic control and protection. But at the same time, it would be useful to install an RCD unit that can de-energize the installation in case of emergency.

When performing electro installation work requirements must be met normative documents governing the installation of electrical equipment. All electrical connections must be carefully insulated. The connection diagram of the air curtain must ensure the safety of the unit operation, especially for places with large quantity people passing through.

It is considered more difficult to connect installations with water heat exchangers. Such units can be connected to the network central heating or hot water supply. To ensure the efficiency of work, in some cases it is necessary to resort to installing an additional circulation pump, capable of increasing the heat output of the curtain.

Scheme electrical connection practically does not differ from a standard electric curtain. The difference lies in the possibility of using wiring with a smaller cross section (the power consumption of water devices is significantly less). The requirements for the presence of grounding and protective automation devices also remain in force.

The air curtain is connected to the heat carrier source using special devices (collectors). In this case, you should pay attention to the correct connection (incoming and outgoing energy carrier flows).

Devices whose task is to separate air masses are called a thermal curtain. They help keep optimal parameters microclimate indoors, becoming an obstacle to the entry of air through windows or doors. In winter, such devices prevent cold air from entering buildings, and in summer they keep the air conditioner running.

Basically, such equipment is used in rooms with high traffic and area, such as shops, salons or offices.

Existing varieties

The principle of operation consists in the suction of ambient air and its sharp supply with a stream. There is a distribution of systems, depending on the principle of operation:

• with air heating, which are used in rooms various types. They do not let in cold air in winter, and hot in summer;
• without heating function. They are used in rooms where the air temperature is lower environment. Then the device becomes a barrier to warm air outside.

The type of air curtains with a heating function is most often used due to its versatility. Depending on the present element, thermal curtains are electric and water. In the first case, a heating element is used, and in the second - hot water in the heat exchanger. electrical view much easier to install and operate, but takes a lot of electricity.

There is also a division depending on the installation of devices:

• suspended horizontal, attached to the ceiling and wall above the doorway;
• vertical, which are located on the floor and wall;
• built-in, they are mounted in suspended structures. Then only the grate through which the air flows will be visible on the ceiling.

The first type is the most popular in everyday life due to its practicality. After all, basically the curtains are installed above the doorway or window. Then the choice of equipment is based only on the length of the curtain, which must be greater than the width of the opening.

The models of thermal curtains offered on the market are designed for a certain installation height. Therefore, for the effective use of the device, it is important to strictly adhere to the installation scheme of the air curtain and install it taking into account the parameters indicated in the instructions. The horizontal arrangement is optimal solution if the door opens into the room, then the equipment will reliably protect against the penetration of cold air.

For rooms with a high opening, experts recommend using vertical installation of equipment - this will ensure the proper effect of air flow. If the air curtain is mounted on the side of the opening, the device does not allow drafts to pass through the entire exit plane.

According to the principle of operation, horizontal and vertical devices do not differ, however, they must be installed strictly for their intended purpose. Otherwise, the curtain will not last long, during operation, breakdowns will begin, leading to defective operation or failure of the entire system.

Equipment selection

Before buying certain equipment, you should consider the following indicators:

• type of heating element;
• instrument length;
• device performance;
• method of installing a thermal curtain;
• the ability to control the system (thermostat or remote control).

Beforehand, it is necessary to make a calculation of the required equipment, the length of the selected thermal curtain must match or be greater than the width of the opening. Otherwise, the air flow will not block the opening, and the device will be ineffective. The task of the outgoing air is to ensure its rapid passage to the floor. Then a small part goes outside, but the main flow goes into the room. In some cases, it is required to install several units at the same time, which will save set temperature and prevent drafts. For a standard doorway, a curtain with a capacity of 1000 m3/h is required, for a window - 300 m3/h.

Mounting options

The most common variant horizontal installation with the lower location of the discharge area. Before carrying out any work, you need to carefully study the instructions, the manufacturer indicates the exact recommendations for installing the equipment. The quality of equipment installation directly affects its operation, therefore, when deciding to independently install thermal curtains, you should clearly follow the instructions. The process will require the following resources:

• perforator;
• screwdrivers;
• level;
• consoles;
• anchor;
• bolts, nuts, screws;
• mounting brackets.

The algorithm of work consists of two stages:

1. Fastening the mounting brackets, for this mark points at a distance of 60 cm and drill holes. Installation is carried out in the upper or lower position.
2. Curtain screwing. The equipment is brought in such a way that the screws go into the grooves of the brackets, securely tightened with a screwdriver.

If installation is to be carried out to beams or ceilings, then threaded holes are preliminarily made in the top panel. Further, air-to-air curtains are suspended on three screws, for their fastening on the rear wall of the equipment there are holes in the shape of a keyhole.

If a column of two curtains is being installed at the same time, then the purchase of special inserts is required. They are attached with anchor bolts. One edge is fixed to the floor, before that, the insert is set at the required angle to the gate. The second edge is applied to the lower part of the curtain and tightened with a fastener. Next, the devices wind up for each other and fix the inserts with bolts. To fix the column to the wall, a console is attached to the upper curtain. The maximum allowable column height is 3.5 m.

Air curtain connection

Upon purchase of a thermal veil the cable and a plug for connection is included in the package. But sometimes a fixed connection is required, that is, without a grounding plug. In this case, all work must be carried out by a qualified electrician through the central switch. As for the wire, a special type of cable is used during installation, in addition, sealing rings must be present to ensure safety during operation.

Before starting the equipment, check the operation of the ventilation system, troubleshoot. This is necessary due to negative impact pressure difference on the operation of the air curtain, the air flow may be an inefficient way to maintain the microclimate parameters.

Maintenance

For long and quality work of the air curtain, it is important to clean the elements of the equipment regularly. Performance is affected by the cleanliness of the following parts:

• exhaust and air intake grilles;
• corps;
• fan impellers;
• electric motor.

Therefore, it is worth regularly checking the condition of the system elements and ensuring quality Maintenance. For example, if a lot of dust collects on the fan impellers, then vibration oscillations begin. This causes noise, and over time, the bearings of the electric motor wear out. Experts recommend cleaning once a quarter, but it all depends on the environment. When maintaining all the conditions of proper operation, thermal curtains will provide comfort in the room for a long time.

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.

Selecting a location for installation

Curtains are mounted only indoors. The specific placement will depend on several parameters, the main of which is the zoning of the serviced site with its delimitation by temperature areas. As a rule, installation is carried out at the entrances and openings, where air flows with different microclimatic characteristics collide. At the same time, air curtains are prohibited in rooms where flammable substances are located, in vehicles, mines and automated production facilities. If the room meets the requirements of the installation, you can proceed to the selection and determination of the optimal configuration for the installation of equipment.

Horizontal and vertical placement

Regardless of the installation point, the direction of air flow should not be obstructed by third-party objects, structures and communications. Also, the unit should not be affected by other climate equipment, even if it is located at a distance. However, a cascade arrangement of several pieces of equipment is allowed. Installation can be carried out horizontally and vertically. As a rule, installation is made horizontally. This is a typical and most common equipment layout, but it also provides for a shutter speed of 15-20 cm directly from the boundaries of the opening.

For vertical installation, please note that the air outlet direction should be as close as possible to the opening. In turn, the exit nozzle section is oriented to the level of the upper border of the door frame. In both installation configurations, about 25 cm of viewing space must remain, which will allow the air curtain to be serviced. The vertical installation itself is advantageous in that it allows easier access to the structure. Typically, such installation is carried out on the sides of the opening, allowing the location of two units that provide a balanced regulation of the microclimate.

Equipment installation

Most models are guided by the installation either to the right of the opening, or in the upper part - a horizontal placement method. Installation is carried out using self-tapping screws.

If a water thermal curtain is used, then first unscrew the hardware on which the front cover of the housing is attached. At this stage, it is necessary to remove the water heat exchanger for further installation of the curtain box.

Then the technical window for spigot integration opens. In some systems, this requires cutting the factory jumpers. The housing is mounted on a prepared place, and then the heat exchanger is reinstalled in the appropriate niche. Typical installation does not require preliminary disassembly for the preparation of communications. Such systems can be mounted immediately at their destination using self-tapping screws, brackets, and profiles - the specific type of fastener depends on the design parameters of the equipment. In any case, the kit will contain the necessary fittings for mounting.

Connecting equipment

The system is entered into the communication infrastructure by means of branch pipes or electrical communications - depending on whether water or electrical principle work is provided. In the case of a water system, plumbing fittings are connected through fittings, adapters, hoses and are regulated by a shut-off valve.

On some models, accessories can be used to expand functionality thermal curtain. water structure, for example, may include If it is absent, then in without fail a water filter is provided. Electrical systems connect to the network using circuit breakers. This device must completely remove voltage from the device. Installation wiring is organized using a three-core cable with a cross section of 1 sq. mm. The conductor must be made of copper. Additionally, fuses and other means of electrical protection are introduced into the system, which should be selected based on the characteristics of the local power supply.

System management

Usually air curtains are equipped with panels with hardware or touch control and remote control, through which you can also adjust the operating mode of the equipment. Typically, devices have several modes of operation, providing for different throughput. The main controlled element of the system is the fan - through the panel or remote control, for example, you can set the optimal speed of its rotation.

If you are installing a thermal curtain on a water coolant, then the regulation possibilities should be calculated in advance, since they are provided structural elements. In particular, the use of the remote control will be possible only if the mixing unit, valve and thermostat are optionally included in the infrastructure.

Maintenance

During operation ventilation systems are subject to pollution. Therefore, the structure should be periodically disassembled within the limits of the permissible instructions and the internal and external surfaces should be cleaned. Special attention assigned to water models. Such curtains are sensitive to mechanical impact on the coolant circulation circuits, due to which there is a risk of leakage. Checking the integrity of water communications is the main task of maintaining such systems. Also, the air-thermal curtain has its own characteristics of content. In the operation of such systems, attention should be paid to electrical safety, eliminating the risks of overloads and short circuits in the wiring.

Trouble-shooting

Often there are problems with fan installations. If this functionality does not work, then you should check the wiring, the presence of voltage in the network, the motor of the fan itself and the correct operation of the control devices. By the way, in order to protect the system from such situations, it is important to install a thermal curtain with reliable insulation of the supply cable.

Standard insulation may not be enough, so it will not be superfluous to immerse the wire in a protective corrugated pipe. And also, if a leak appears in the water system, then the plumbing infrastructure is checked with the subsequent restoration of its tightness. Most of the problems arise precisely because of violations in the communication channels.

Safety precautions

During the operation of the air curtain, it is necessary to adhere to the following safety rules:

• It is impossible to eliminate the leakage of the coolant on your own, if in this moment line is pressurized.
• It is impossible to carry out repair measures until the electrical infrastructure is de-energized.
• Regardless of the principle of operation of the equipment, the installation of a thermal curtain must be carried out with disconnected communications.
• In conditions of reduced negative temperature coolant must be completely drained.

Conclusion

The quality of the air curtain will depend not only on compliance with the rules of installation work, but also on how correctly the choice of a particular model was made. When buying a device, temperature limits, the number of people passing through the opening, the area of ​​\u200b\u200bthe room, etc. are taken into account.

As for manufacturers, preference should be given to Ballu and Dantex models - these are specialized manufacturers climate systems.
