Electrical diagrams of air curtains teplomash. How to choose the right thermal curtain? Vertical installation of a thermal curtain

The purpose of the thermal curtain is to protect a room with an open entrance from the penetration of cold air from the street.

It can serve rooms in which the doorway does not exceed a height of 3.5 m.

What should I pay attention to before installing thermal curtains?

Installation Methods

Installation can be done in two ways: vertical and horizontal installation. When installing thermal curtains, it is necessary to take into account the following nuances:

• the quality of equipment operation can be significantly affected by low pressure inside the room. Make sure the ventilation system in the building is balanced;
• For maximum effect, it is necessary to mount air curtains as close to the opening as possible. In this case, the width of the air flow should be equal to the width (height) of the doorway;
• Basically, the equipment is located with inside opening. Thermal air curtains installed from the outside are designed only to protect the doors of freezers;
• the direction and speed of the air flow must be adjusted. In particular difficult cases the air flow should be directed at an angle of 5-10 degrees in the direction of the street;
• The power of the air curtain can be different: low power - 2-6 kW, medium power - 9-18 kW, high power - 20-100 kW.

Necessary tools

To install the equipment, you will need the following set of tools:

1. perforator;
2. consoles;
3. mounting brackets;
4. plumb or level;
5. bolts M10;
6. anchor bolts;
7. screwdriver;
8. nuts, screws.

Air curtain installation sequence

In most cases, the installation of thermal curtains is carried out directly above the open opening. The quality of its work depends on how competently the connection of the thermal curtain will be performed. Therefore, try to adhere to the following algorithm:

• Mark and drill holes for mounting brackets. The length of the center distance should be 600 mm. On the wall, install the mounting brackets in the lower or upper position, adhering to the minimum distances and restrictions (drawing A).

Move the air curtain to the side so that the mounting screws fit into the grooves of the mounting brackets. Then tighten the screws firmly (drawing B).

• If you decide to hang the air curtain, the mounting brackets must be turned as shown in drawing C.

• If you decide to install a thermal curtain on beams and ceilings, do threaded holes in the top bar. (When installing on a false ceiling, make sure that the air supply is sufficient so that the operation of the ventilation system does not interfere with the normal operation of the air curtain).
• Pay special attention to air flow. It is necessary to mount the air curtain in such a way that it does not create barriers to the incoming and outgoing air flows.

When installing thermal curtains, carefully read the manufacturer's instructions. Most air curtains only allow horizontal installation with the lower placement of the injection area. over big doorways several devices are installed close to each other.

Special types of installation of thermal curtains

When mounting the air curtain on a wall or beam, it is hung on three screws, which are screwed directly into the attachment points. All curtains have corresponding keyhole openings on the back side.

When installing thermal curtains, it is convenient to use a French screwdriver for wood. In this case, it is necessary to use safety brackets, which must be installed in the lower or upper area of ​​the air curtain with fixation to the wall.

Mounting of thermal veils on screws to a wall or a beam is also possible. To do this, six holes with M6 thread are provided on the rear wall of the air curtain. When installing thermal curtains above the gate, the devices must be mounted close to each other in order to prevent a gap between air flows. The minimum mounting gap between the air curtains is 50 mm.

Air curtain connection

The air curtain is supplied with a flexible cable and a plug, which has a ground connection. Fixed connection (without using a plug) must be made through a central switch with an air gap of more than 3 mm.

The connection of the air curtain must be carried out by a qualified electrician in compliance with the relevant regulations.

The air curtain is mounted using SO5VV-U or similar wires. The upper panel of the air curtain has two knockouts with a diameter of 29mm and four with a diameter of 23mm. At the cable entry into the curtain, sealing rings are used, which must comply with the protection class of the device.

If the thermal curtain is installed correctly, it will create comfort in the room for a long time.

Ensuring the comfort of staying in the premises of the house at any time of the year is one of the main concerns of the owners. But efforts to insulate the walls, to install an appropriate heating system, may be in vain if the heat is freely released through windows or doors. This is especially true of those buildings in which, for one reason or another, they open very often or even long time remain in the open position.

A simple situation: the owners of the house open some kind of family business - a workshop, a store or office space. On the one hand, numerous customers are great, but at the same time, frequent opening of doors can quickly cool even a well-heated room, and this is a serious energy cost. Another option is the specifics of the activity of a private workshop, equipped in a garage or in a special annex, which requires constant or very frequent opening of the gate (). In order to provide ourselves with acceptable conditions for effective productive work in winter time will have to spend exorbitant forces and means to maintain a normal temperature. But there is a way out - in both cases, a thermal curtain on the front door should help.

To make it easier to understand the purpose of the thermal curtain, you should first understand how cold air enters the house through open doors. This process is due to several reasons - the difference in temperatures outside and inside the room, caused by this difference, a different pressure level. And plus a very important reason for this is the movement of air masses along the street - the wind, the vortex flows created by passing vehicles, etc.

Fragment "A" shows the movement of cold and warmer air flows through the doorway in "calm" conditions. Cold air is always denser, and with its increased pressure it simply squeezes out lighter warm air. At the same time, the cold stream is always located closer to the floor - everyone, for sure, in their everyday practice, felt how it “pulls cold” from below from under a loosely closed door.

The wind component is added to this quite usual exchange (fragment "B"). Of course, it is a variable value, it depends on the direction and speed of the wind, stability or periodic gusts, the size of the doorway and other parameters, but in general, most often such an application of the air mass movement vector is still present.

As a result, as a result of the addition of both factors, the picture shown in fragment “C” is obtained - the “channel” for the entry of cold air increases even more in area, occupying most of the doorway. In such conditions, if the door has to be kept open or often opened, no heating equipment that will “thresh” idle will be able to cope with the heating of the room. In addition, constant strong drafts walk around the rooms, which dramatically increase the likelihood of colds, even if people are dressed “for the season”.

And what if you apply a sufficiently narrow, but dense directional air flow. So that its pressure exceeds even theoretically possible values ​​of external and internal pressures (fragment "D"). If you correctly calculate the parameters of such a flow, then it will become an obstacle to the exchange shown above, blocking off the air masses outside and inside the room. Somewhat bending its configuration under the influence of external pressure on it, the flow still retains the necessary “collection” and is split up only upon reaching the floor surface, dividing into two directions. A certain part goes outside, but still more significant - returns back to the room (fragment "E").

How can this effect be used?

• Picture "a" - winter time. The air receives the necessary heating, and the resulting curtain not only does not let the cold masses in and does not allow the heated masses to break out, but also, returning to the room, “helps” the heating system.
• However, it would be a big mistake to consider the air curtain too “narrowly”, only as a kind of heating device. The picture "b" shows her work in the warm season. The situation is reversed - the cool internal air does not go outside (although its density is higher in the case under consideration), but the heated summer heat street - can not enter the room. Thus, the temperature in the rooms is comfortable for people to stay.
• But that's not all. Regardless of the season and operating mode, such a curtain performs another important function (picture "c"). A lot of dust is always suspended in the street air, especially if there is a busy highway or even a railway line in the immediate vicinity. For the same reason, the air can be overfilled with exhaust gases. Naturally, if all these “bonuses” enter the premises, the local microclimate will suffer significantly. But the thermal curtain will quite cope with such a problem. This also applies to falling snow, light drizzle, and in summer time- hordes of small annoying insects.
• And one more application. With the help of such air curtains, it becomes possible to zone the premises according to the type of microclimate created in them. For example, it is possible to "fence off" a spacious hall at the entrance (where an elevated air temperature is not particularly needed, and an unreasonably large amount of energy will be spent on heating such a room) from internal living or working premises, without even installing additional doors.

So, creating an air curtain helps to cope with a lot of problems. And all this can be achieved by installing a special device.

Despite the fact that the air curtain itself is a consumer of electricity, its use provides considerable benefits. So, practice shows that correctly chosen and installed device allows you to save up to 30% on energy resources spent on space heating in winter and air conditioning in summer. And if the owner thinks more broadly, he will not be able to help but notice that the absence of cold drafts will drastically reduce the cost of medicines for households or sick leave for his staff.

Another important advantage is that with such a rich range of possibilities, the device itself practically does not take up useful space in the space of the room.

For clarity - a small animated video on the principle of operation of thermal curtains:

Video: how a thermal air curtain works

How the air curtain works

As a rule, an air thermal curtain is an electrical device assembled in a housing of a pronounced elongated shape.

In the upper part of the housing there is a grate (pos. 1) through which air is taken from the room.

At the bottom there is an output slit-like window (nozzle) (pos. 2), which can be equipped with movable blinds like blinds.

The control elements (pos. 3) can be located on the body itself, in a place accessible for visual control and manipulation. The control panel, in addition, can be remote, and be located on the wall of the room in a convenient place.

The case may have a terminal block for connecting to the power supply, but on household-class models, most often there is an already connected cable with a plug for connecting to an outlet (item 4).

On many modern models besides, it is also provided for remote control using an infrared remote control (just like in split-system air conditioners).

The main task of the thermal curtain is to create a powerful air flow. And this means that the blower fan becomes the main unit of the device. Usually these devices are not of the usual bladed, but of a turbine type, of two varieties - a more compact radial (pos. "a") or an elongated tangential type (pos. "b").

Pos. "in" is a heat exchanger where the air flow receives the necessary heating if necessary. The vast majority of models have an electric heat exchanger, where the air is heated by coils or heating elements. However, there are stationary models of thermal curtains that are connected to existing water heating circuits.

Many modern air curtains have built-in filters, which at the same time purify the air driven through the device from suspended dust.

Electronic circuits of modern air curtains provide multi-level protection against short circuit, breakdown to the case, overheating, have modules for thermostatic control of the heat exchanger heating level and fan speed.

Classification of air curtains

There are several gradations of classification of thermal curtains.

By location relative to the doorway:

• The classic version of most thermal air curtains is a device with a horizontal installation above a doorway (gate, window, etc.)

• Sometimes, due to various technological or aesthetic reasons, installing a thermal curtain from above may be impossible or irrational. For such situations, vertical devices are provided, which are installed in "columns" on one, or even on both sides of the doorway.

Many models in this regard have increased versatility - their design allows, taking into account the specifics of the room, to install them both in a horizontal and vertical position.

By installation type:

Most models have a metal case, the execution of which involves mounting the device on the wall. However, if any increased requirements are imposed on the interior design of the room in terms of design, then you can choose a thermal air curtain that is built into the ceiling or wall along the height of the opening.

By the presence and type of heat exchanger:

All air curtains according to this criterion can be divided into three groups:

• Curtains with electric heat exchanger. Usually in the classification they are marked with serial designations RS, RM or RT.

Advantages - the maximum simplicity of the device and installation of the device, high efficiency, the ability to smoothly adjust the temperature of the heating of the air flow.

Conventional spirals were used as heating elements on older models, but now this approach has been abandoned almost everywhere, since open heaters “burn through” oxygen and quickly dry the air in the room. Currently, tubular heaters are used according to the type of familiar heating elements, or more modern semiconductor RTS (Positive Temperature Coefficient), which have the ability to self-regulate heating and electricity consumption.

The disadvantages of electric heat exchangers are significant power consumption (not counting the cost of ensuring the operation of the fan), and some “inertia” at startup - the heat exchanger needs a certain time to reach the operating mode.

• Air curtains with water heat exchanger (series RW).

In such models, electricity is consumed only to ensure the operation of the fan and the control group. This, of course, makes water curtains much more economical in continuous operation.

In the housing (outside or hidden) there are branch pipes for connecting the device to the existing circuit of the water heating system (shown by arrows in the figure).

Branch pipes for connecting the supply and "return" of the heating system of the house

The disadvantages of this type of thermal curtains are obvious - this is a lot of difficulties during the installation process. It is necessary to foresee branches from the general contour in advance, and provided that the aesthetics of the interior are preserved, such an operation can be quite problematic. The heat exchanger of such a curtain has a small tubular structure (like a radiator in a car), which will quickly become clogged if a filter device is not provided. In addition, the consumed thermal power of such an installation must correspond to the actual capabilities of the autonomous heating system, so that the connection of the air curtain does not affect the level of heating of radiators in other rooms.

• Air curtains not equipped with a heat exchanger (serial designation - R.V.).

Such devices are used in conditions where additional air heating is not required. They protect well from street dust, gas pollution, insects, from leakage of conditioned air to the outside. They are widely used in industrial practice - for zoning spacious rooms, protecting against the ingress of warm air into freezers or storage, etc.

By power level (performance) and, accordingly, purpose:

• To the series RS include mini curtains with limited scope applications. Their performance is enough to effectively “screen” only small openings, for example, visitor reception windows overlooking a cold hall, or customer service windows in street kiosks, transport cash desks, etc. Usually they are designed for openings no more than one and a half meters high, up to 800 mm wide.

The air flow rate and pumping volume per minute are low. In domestic terms, such thermal curtains are not of practical use.

• Thermal air curtains series RM- this is the most large group appliances that are designed to fit in most existing standard doorways, approximately 2.5 to 3.5 meters high. Including, they are also suitable for or for the transition from the cold hallway to the residential sector of the house.

Middle-class thermal curtain - quite suitable for the front door

Such devices are the most "running". It is these series that are most often equipped with convenient remote units or remote controls management.

• Powerful thermal curtains series RT are used to protect high openings, from 3.5 to 7 meters. It can be the gate of a car repair shop, warehouse or industrial premises, entrances to large shopping centers or buildings of cultural and social purpose.

Very often, powerful installations of the series are referred to this category. RW connected to central heating or hot water supply systems of public buildings and industrial facilities. the cost of water thermal curtains is significantly higher than that of electric models comparable in terms of performance and size.

There are also heavy-duty thermal curtains that can create an air barrier in openings and driveways up to 12 meters high.

How to choose the best thermal curtain

The choice of an air thermal curtain has its own characteristics, which you should definitely familiarize yourself with before going to the store.

In addition to the already mentioned selection criteria - according to the installation site (horizontally or vertically) and the principle of operation of the heat exchanger, be sure to pay attention to the following characteristics:

• The dimensions (to a greater extent - the length) of the device itself, that is, the width of the air curtain it creates.
• Productivity, that is, the ability to pump a certain amount of air per unit of time.
• The power of the heat exchanger.
• Equipped with useful adjustment options.
• Degree of protection, that is, the level of safety of operation of the device.
• For the interior design of the room is important and appearance thermal curtain.

Air curtain dimensions

The determining parameter, of course, is the length of the device. It must provide the required air flow across the entire width of the doorway, not allowing free gaps for the penetration of cold or dusty masses from the outside. As a rule, the length of such devices lies in the range of 600 ÷ 2000 mm.

For standard doorways, curtains with a length of about 800 mm are usually purchased. With a competent approach, it should be taken into account that the width of the air flow should be at least equal to the clearance of the doors, but even better if it is slightly larger.

There is one more nuance. The technology for the production of air blowers somewhat limits the length of the turbine (up to 800 mm), since when such dimensions are exceeded, vibration phenomena increase sharply, which requires a rather expensive “suspension”.

Turbine length is usually limited to 800 mm

Trying to minimize costs when producing "long" models, many manufacturers follow the path of simplification: they place the electric drive in the center of the device, and the turbines on the left and right, achieving the desired length. In such an arrangement, a serious drawback may lurk - in the center of the created air flow, a "failure" or an area of ​​\u200b\u200blow pressure can form, which can become a loophole for air to enter from outside.

If the width of the doorway is greater than the length of the model you like or the devices on the market in general, it makes sense to purchase two curtains (and sometimes more) and install them close to one another.

Air curtain performance indicators

It is quite clear that the thermal curtain should create an air flow, the “density” of which, that is, the internal air pressure, would exceed the external one at any point in the doorway, from the installation site to the floor (opposite side of the door).

Calculations have determined that such required parameters are retained when the speed of the air layer at the meeting point with the barrier is at least 2.5 m/s. Naturally, the speed due to air resistance drops as you move away from the device.

The speed and density of the air flow depend on the working diameter of the turbine, the speed of its rotation and, therefore, on the overall performance of the injection unit. For example, the table below clearly shows the dependence of the effective range of the thermal curtain on the diameter of the turbine - in some cases, you can focus on such indicators:

Distance from the outlet nozzle of the air curtain	Air flow rate depending on the fan installed in the air curtain
	Fan working diameter
	Ø 100 mm	Ø 110 mm	Ø 120 mm	Ø 130 mm	Ø 180 mm
0 m	9 m/s	10 m/s	12 m/s	14 m/s	-
1m	7 m/s	7 m/s	11 m/s	10 m/s	-
2 m	4 m/s	4m/s	8 m/s	7.5 m/s	-
3m	1.0 ÷ 2 m/s	1.5 ÷ 2 m/s	5 m/s	6 m/s	-
4 m	-	-	2 ÷ 3 m/s	5 m/s	-
5 m	-	-	-	3 m/s	-
6 m	-	-	-	1.0 ÷ 2 m/s	-
0 m	8.5 m/s	8.5 m/s	12 m/s	12 m/s	15 m/s
1m	6.5 m/s	6.5 m/s	10 m/s	9.5 m/s	13 m/s
2 m	3 m/s	3 m/s	7 m/s	9 m/s	11 m/s
3m	1.0 ÷ 2.0 m/s	2 m/s	4 m/s	5.5 m/s	9 m/s
4 m	-	-	1.0 – 2.0 m/s	4 m/s	7 m/s
5 m	-	-	-	3 m/s	5 m/s
6 m	-	-	-	1.0 ÷ 2.0 m/s	3 m/s
7 m	-	-	-	-	2 m/s
8 m	-	-	-	-	1.0 – 2.0 m/s

Most often, in the technical documentation for the product, the manufacturer directly indicates the maximum opening dimensions for a particular model. The performance of the system is also indicated there, usually in cubic meters per hour. It is believed that for a standard doorway with dimensions of 0.8 ÷ 1.0 × 2.0 ÷ 2.2 m, a pumping rate of 700 ÷ 900 m³ / h is considered optimal. However, if you look at the catalogs of equipment, then you often find curtains with much more modest values. There is no unanimity of views of manufacturers on this issue.

There are special algorithms for calculating the parameters of thermal curtains, which take into account not only the linear indicators of the installation site, but also the location of the entrances to the building, average temperature differences for a particular region, the prevailing wind direction, etc. Such calculations are the lot of specialists, and if it is not enough for someone to choose a model of the characteristics declared by the manufacturer, then you can contact the appropriate design organization.

Why is the performance issue so acute? The efficiency of the air curtain directly depends on it.

• Fragment No. 3 schematically shows the operation of a correctly selected model of a thermal curtain. The air flow retains its "density" to meet the barrier, and then about ¾ is reflected back into the room.
• Fragment No. 2 - a thermal curtain with excess performance was installed. The speed at the floor surface is too high, and the flow is broken up in such a way that a significant part of it is carried out. Of course, this leads to completely unjustified losses of expended energy.
• And fragment No. 3 shows what will happen if the capacity of the created stream is not enough. The external pressure of the air masses outweighs, and a wide "window" for cold street air opens in the lower part of the doorway. The point of installing such a thermal curtain is generally very doubtful - it simply does not play any significant role.

Thermal power of the air curtain

Oddly enough, this indicator is not decisive for a thermal curtain - this is their fundamental difference from seemingly related devices - heat guns or floor or floor heating convectors installed at doors and windows.

The operation of the air curtain heat exchanger is not aimed at maintaining the optimum temperature in the room, but only at partial compensation of heat losses through the door. Clear. that part of the heated air, when operating in the "winter" mode, returns back to the room, but this circulation should only have an auxiliary effect on the heating system operating in the building, but not replace it in any way.

At high speeds of air pumping, giving it too high a temperature is a difficult and very energy-consuming task. Typically, in most models, the temperature increase is limited to 20 degrees at best, and on thermostatic controls, the maximum value, as a rule, does not exceed 30 ° C - more is not required from a thermal curtain.

But the total power consumption is worth paying attention to. The parameters of a dedicated power line, an automatic switchboard in a house, an RCD, etc. will depend on this indicator.

Control and protection systems

All electric air curtains are equipped with two levels of control: one is responsible for creating and maintaining a given performance "by air", and the second - for the operation of the heat exchange unit. At the same time, the protection system will never allow the heater to be turned on when the turbine is not working, which ensures that the device is protected from overheating.

The simplest, inexpensive models have preset levels of performance and heating of heating elements that cannot be changed (the only exception is that you can turn off the heating completely when operating in the "summer" mode. However, such cheapness and simplification of the design are hardly justified for use in a private house - everyone wants be able to optimally adjust the microclimate in the room.

More complex models are equipped with step adjustment, for example, they have 2 ÷ 3 turbine power levels and the same number of heat exchanger heating gradations.

However, in recent years, electronically controlled thermal curtains have become the most popular, which opens up the possibility of smooth fine adjustments to the owners.

The presence of a thermostatic sensor will significantly save on electricity consumption - the automation will turn on or off the heating element unit only as needed.

Thermal curtains can be equipped with remote control units, which are located on the wall. Easy to use models with remote controls.

Like all modern electrical appliances, a thermal curtain must be equipped with several degrees of protection against short circuits, overheating, phase breakdown to the case, voltage surges, etc.

Designers and designers of manufacturing companies try to make thermal curtains outwardly so that they do not spoil the interior of the room with their appearance. Some models can even become a kind of decoration for the entrance group.

Thermal curtain installation

Self-installation of thermal air curtains, although not welcomed by manufacturers, is still quite possible, especially when it comes to the most common ones - completely electrical models. In terms of complexity, it is much easier installation domestic air conditioner.

Can I install the air conditioner myself?

Installation of an air conditioner usually requires special skills, since when installing a split system, you will need to properly charge it with refrigerant. How it is produced - in a special publication of our portal.

The main thing is to provide a power line of the required power, the necessary safety and protective devices (automatic and RCD), a connection point for the device.

As a rule, the air curtain kit includes brackets (or a mounting panel), fasteners for hanging it over a doorway. The entire installation will basically consist of careful marking, fixing the mounting parts on the wall plane and then hanging the device itself. It can be quite massive, so you should exercise reasonable care, or even better, enlist an assistant.

After installing the appliance, if it is equipped with adjustable shutters, they should be positioned at an angle of approximately 30° from the vertical towards the entrance. On many models, this flow slope is provided by the design of the air nozzle itself.

It may be necessary to lay a signal cable and mount the remote control unit on the wall. All these nuances are always described in detail in the installation manual of a specific model, and you should familiarize yourself with them in advance, even when choosing a curtain, in order to really assess your capabilities.

Installation of a curtain with a water heat exchanger is a much more complex undertaking, often requiring special thermal engineering calculations and the installation of additional collector or pumping equipment. It is not worth it to take on such an activity without experience.

Video: a few recommendations for choosing a thermal curtain on the front door

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, 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 case is attached. At this stage, it is necessary to remove the water heat exchanger for further installation of the curtain box.

Then opens technical window for spigot integration. 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. A typical installation does not require prior disassembly to prepare 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 - it depends on whether the water or electric principle of operation 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.

In some models, with the help of auxiliary devices, it is possible to expand the functionality of the air curtain. water structure, for example, may include. If it is absent, then a water filter is mandatory. Electrical systems connected 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 possibilities of regulation should be calculated in advance, since they are provided by 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 contamination. Therefore, the structure should be periodically disassembled within the limits of the permissible instructions and the internal and external surfaces should be cleaned. Particular attention is paid 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 the line is currently operating under pressure.
• 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 low negative temperature, the coolant should be completely drained.
