Wiring diagram for the air curtain above the door. How to install a thermal curtain - connection diagram and installation. Selecting a water thermal curtain

Thermal curtain is designed to protect a room with an open entrance from the penetration of cold street air. This is an ergonomic and economical solution if the height doorway does not exceed 3.5 m. In small trade pavilions, knowing how to connect a thermal curtain directly above the windows will help.

Thermal curtain: what is it used for, how does it work

Thermal curtain is relevant for rooms with large human traffic

Thermal curtain is special device, forcing air flow, which creates a barrier to air exchange between the room and the outdoor environment. It can be used all year round:

in winter, the heat shield prevents cold air from penetrating through window and/or door openings;
In summer, the air flow does not release conditioned cool air into the street.

The absence of movement of air masses prevents the formation of drafts. Intrusive insects and unpleasant odors from outside do not fly into the room. The advantages of air curtains are especially relevant for warehouses, retail, household and cultural and leisure premises.

The mechanism of action is as follows:

the fan sucks in room air through the perforated wall of the housing;
the air heater provides the air flow with the desired temperature;
radial fan - a turbine forces air into the plane of the opening through a nozzle in a single jet.

Types of devices

Classification of thermal curtains is possible on several grounds. So, according to the type of energy carrier they distinguish following types these devices:

electrical - the equipment weighs little, is convenient and quick installation, require sufficient electrical power;
water - suitable for industrial premises with large dimensions of entrance openings, require connection to a hot water supply system;
gas - work at any temperature conditions, however, it is necessary to strictly observe safety precautions during installation and operation in order to avoid explosive cases.

According to the method of equipment installation, the following groups are distinguished:

horizontal - one of the most popular options, does not take up space, is installed above the opening;
vertical - for rooms with stretch ceilings or a small opening between the top line of the door and the ceiling.

Based on the heating element options, thermal curtains are divided into spiral, heating element and stitch. Depending on the mode of operation, devices of constant and variable action are distinguished. Air can be taken both indoors and outdoors, etc.

Preparation for installation, necessary tools and materials

When choosing a device, take into account the width or height of the opening (depending on the intended installation method) - the minimum dimensions of the device must correspond to 2/3 of the required length. If the opening is wide or high enough, then you will need to purchase several thermal curtains and install them in one row.

Before starting installation, prepare the following tools:

screwdriver;
perforator;
building level;
roulette;
a simple pencil;
self-tapping screws;
bolts;
screws;
nuts;
fittings for fastening (usually included in the kit);
pendulum suspension (if necessary, ceiling mounting);
connecting kit (for fastening two or more curtains together);
consoles.

Installation options for thermal curtains

The installation option for a thermal curtain depends on the width of the opening, for which it will form a kind of protective shield:

if the opening width does not exceed 1.5 m, then the most optimal method is the horizontal method;
with a width of more than 2 m, it is more reasonable to provide a vertical installation option.

Vertical

A vertical thermal curtain can organically fit into the interior of the room

Installation work is carried out in accordance with the manufacturer’s instructions, however, several common elements can be identified:

The fixing points of the brackets are marked at a distance of 10 cm from the edge of the opening.
Fastening elements are installed on the housing, and then the entire system is securely mounted on the wall.
Connect and check the functionality of the equipment.

Horizontal

Horizontal fixation provides two options - ceiling mounting or directly on the wall above the opening. In the latter case, the entry of cold air from the street is practically eliminated. Installation is carried out according to the following algorithm:

Step back 15 cm from the upper edge of the opening and mark the lower line of the housing location with a pencil.
Along the edges of the body, the mounting locations for the brackets are marked and holes are drilled.
The brackets are secured with bolts and nuts to the body, and then the entire structure is securely fixed to the wall.
Conduct a connection to the power grid and a test run to check the functionality.

How to connect correctly

The heat curtain is connected through a separate machine on the electrical distribution board. For installation use a three-core copper cable cross section 1 sq. mm. Additionally, the circuit includes fuses, the selection of which is carried out taking into account the operating characteristics of the local electrical network.

The nuances of connecting curtains from various manufacturers

Ballu is one of the most popular manufacturers thermal curtains

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

selection circuit breaker and going from it to the installation power cable carried out taking into account the parameters recommended in the instructions;
taking into account the power consumption, the connection is made either from a single-phase power supply of 220V, or from a three-phase power supply of 380V;
The control panel is mounted outside the curtain air flow zone to eliminate the dependence of the thermostat operation 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 voltage 380V;
The control cable is laid using the “hidden wiring” method.

Thus, by selecting a thermal curtain according to a number of different parameters characteristic of the room requiring a protective shield, you can forget about drafts, unpleasant odor and annoying insects. Installation of equipment is accessible to anyone, and to connect the device to the electrical network, you should use the services of a specialist with the appropriate clearance group.

The purpose of a 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 you pay attention to before installing thermal curtains?

Installation Methods

Installation can be done using two methods: vertical and horizontal installation. When installing thermal curtains, the following nuances must be taken into account:

The quality of equipment operation can be significantly affected by reduced pressure inside the room. Make sure the building has a balanced ventilation system;
For maximum effect, it is necessary to install 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 on the inside of the opening. Thermal curtains installed with outside, are intended only to protect freezer doors;
The direction and speed of the air flow need to 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 thermal curtain varies: low power- 2-6 kW, average power- 9-18 kW, high power - 20-100 kW.

Necessary tools

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

perforator;
consoles;
mounting brackets;
plumb line or level;
M10 bolts;
anchor bolts;
screwdriver;
nuts, screws.

Thermal curtain installation sequence

In most cases, thermal curtains are installed directly above the open opening. The quality of its work depends on how competently the heat curtain is connected. Therefore, try to adhere to the following algorithm:

Mark and drill holes to attach the mounting brackets. The length of the center distance should be 600 mm. Install the mounting brackets on the wall in the lower or upper position, adhering to the minimum distances and restrictions (Drawing A).

Move the curtain to the side so that the mounting screws fit into the grooves of the installation mounting brackets. Then tighten the screws tightly (Drawing B).

If you decide to attach the curtain on a suspension, the installation brackets must be unfolded as shown in drawing C.

If you decide to install a thermal curtain on beams and ceilings, make threaded holes in top panel. (When installing on a false ceiling, it is necessary to ensure that there is sufficient air flow and that the operation ventilation system will not be a hindrance in normal operation air curtain).
Pay special attention to air flow. The air curtain must be mounted in such a way as not to create obstacles to the incoming and outgoing air flows.

When installing thermal curtains, carefully read the manufacturer's instructions. Most thermal curtains allow only horizontal installation with the discharge area located at the bottom. Above the big ones doorways Several devices are installed close to each other.

Special types of installation of thermal curtains

When installing a thermal curtain on a wall or beam, it is suspended on three screws, which are screwed directly into the mounting points. All curtains have corresponding keyhole-shaped holes 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 curtain and fixed to the wall.

It is also possible to install thermal curtains with screws to a wall or beam. To do this on back wall The thermal curtain has six holes with M6 threads. When installing thermal curtains above the gates, the devices must be mounted back to back to avoid a gap between the air flows. Minimum installation gap between curtains is 50 mm.

Connecting a thermal curtain

The curtain is supplied with a flexible cable and a plug that is grounded. 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 heat curtain must be carried out by a qualified electrician and must comply with the relevant standards.

To install the air curtain, wires of type SO5VV-U or similar are used. The top panel of the 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 meet the protection class of the device.

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

Devices whose task is to separate air masses are called thermal curtains. They help preserve 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 operating.

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

Existing varieties

The principle of operation is to suck in ambient air and suddenly supply it with a flow. There is a distribution of systems, depending on the principle of operation:

with air heating, which are used indoors various types. They don't miss in winter cold air, and in summer – hot;
without heating function. They are used in rooms where the air temperature is lower environment. Then the device becomes a barrier to warm air from outside.

The type of thermal curtains with a heating function is most often used due to its versatility. Depending on the element present, thermal curtains are either electric or water. In the first case, a heating element is used, and in the second - hot water in the heat exchanger. Electric 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 placed on the floor and wall;
built-in, they are mounted in suspended structures. Then only the grille 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, curtains are usually installed above a doorway or window. Then the choice of equipment is based only on the length of the curtain, which should 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 effective use device, it is important to strictly adhere to the installation diagram of the thermal curtain and install it taking into account the specified parameters in the instructions. Horizontal position 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 air flow effect. If the 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, but they must be installed strictly for their intended purpose. Otherwise, the air curtain will not last long; during operation, breakdowns will begin, leading to inadequate operation or failure of the entire system.

Equipment selection

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

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

It is first 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 escaping air is to ensure its rapid passage to the floor. Then a small part goes outside, but the main flow is directed indoors. In some cases, it is necessary to install several units at the same time, which will maintain the set temperature and eliminate the occurrence of 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 option is horizontal installation with bottom position discharge area. Before carrying out any work, you must carefully study the instructions, the manufacturer indicates precise recommendations for equipment installation. The quality of equipment installation directly affects its operation, so when deciding to install thermal curtains yourself, you should strictly follow the instructions. The process will require the following resources:

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

The work algorithm consists of two stages:

Fastening the mounting brackets, for this purpose, mark points at a distance of 60 cm and drill holes. Installation is carried out in the upper or lower position.
Screwing the curtain. The equipment is brought in such a way that the screws fit into the grooves of the brackets and tightened securely using a screwdriver.

If installation is to be carried out to beams or ceilings, then threaded holes are first made in the top panel. Next, the air-thermal curtains are suspended on three screws; for their fastening, there are keyhole-shaped holes on the back wall of the equipment.

If a column of two curtains is being installed simultaneously, then the purchase of special inserts is required. They are attached using anchor bolts. One edge is fixed to the floor, before this the insert is set at the required angle to the gate. The second edge is applied to the bottom of the curtain and tightened with a fastener. Next, the devices are inserted behind each other and the inserts are secured with bolts. To fix the column to the wall, a console is attached to the upper curtain. The maximum permissible column height is 3.5 m.

Connecting an air heat curtain

When purchasing a thermal curtain, the package includes a cable and a plug for connection. But sometimes it's required fixed connection, that is, without a grounding plug. In this case, all work must be carried out by a qualified electrician via 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 up the equipment, check the operation of the ventilation system and troubleshoot problems. This is necessary because negative influence pressure difference on the operation of the thermal curtain, air flow may turn out to be an ineffective way to maintain microclimate parameters.

Maintenance

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

exhaust and air intake grilles;
housings;
fan impellers;
electric motor.

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

A thermal curtain is a fairly powerful fan heater designed to prevent air, dust, and insects from entering the room from the outside and to prevent air masses from escaping outside the room. In order for the fan heater to perform its assigned functions efficiently, a competent calculation is required, correct installation and connecting the device.

How to properly install a thermal curtain will be discussed in this publication.

Features of choice

The correct choice of a heat curtain is based on the following parameters:

Device installation method.
Dimensions.
Installation performance.

In addition, it is worth paying attention to the heating power and air flow speed created by the fan heater.

Installation method

All are divided into two groups according to the installation method: horizontal and vertical. There is also a small third group of such fan heaters with universal installation capabilities.

The simplest and therefore most common group of thermal curtains are horizontal installations. If the height of the opening is more than 3.5 m and there is a high probability of intensive opening of the doors, then in such cases experts recommend installing one horizontal and an additional vertical curtain. In particularly difficult cases, installation of horizontal heat curtains in several levels is allowed.

If for reasons low ceiling or complex wall geometry, horizontal installation fan heater is not possible, vertical installations must be selected.

Dimensions of horizontal heat curtains

Length standard settings varies from 60 cm to 2 m. Such devices must be located at the top of the door or window opening. For maximum efficiency, you should choose a device that is exactly the width of the opening or slightly wider.

If the length of the opening is more than 2 m, then the best option will use several devices located at the top of the opening. It is necessary to install devices as soon as possible closer friend to a friend so that there are no “dips” in the air flow.

Selecting a device based on air flow speed

The speed of air movement generated by the thermal curtain is written in technical documentation to the device. When choosing, you should take into account that the air flow speed is written only at the outlet of the installation, therefore, when it rises to the height of the opening, the speed will drop.

It has been experimentally proven that the most effective work heat curtains when the air speed at the floor varies within 2.5 m/sec. – 3.5 m/sec. Below is a diagram of the dependence of air speed on the rotor diameter.

Calculation of air curtain performance

To correctly select the performance of a thermal curtain, use the following hint: effective protection opening, 1 m long and 2.5 m high, you should purchase an installation with a capacity of 1000 -1200 m 3. Under such conditions, the air flow speed at the outlet of the device will be in the range of 8-10 m/s, and at the floor - 2.5-3.5 m/s.

You can use the formula for calculating the required air flow speed.

L pr = V * H * IN

Where:
H– opening height;
IN– opening width;
V– speed of movement of air masses.

After obtaining the desired value, you should calculate the required air speed generated by the device to protect the opening from the penetration of air masses from the outside. This can be done using the formula:

L manager = L etc / j * (B / b + 1)

Where:
J– coefficient equal to 45;
b— width of the curtain air channel;
IN– opening width;

For correct selection power of the heating element of the air curtain, it is necessary to know the air temperature in the room. Based on this, you can make a selection of equipment, since in the documentation each manufacturer indicates the difference between the intake and exhaust air.

Q head = 0.24 * L manager * ( t con - t beginning)

Where:
t start - room air temperature during suction;
t kon is the outgoing temperature of the air flow from the device.

Installation instructions for horizontal air curtains

Thermal curtains must be installed by specialists. But it often happens that after the acquisition, and with detailed instructions a decision is made to install the product yourself. And in this, by by and large, there’s nothing to worry about, you just need your hands, the necessary tool and strict compliance with installation and safety regulations.

Before installing the heat curtain, you should know that it must be brought as close as possible to the upper edge of the opening. The device should not be in the opening of a door or window. It should be attached immediately above the opening and in its center. In addition, the manufacturer's recommendations regarding the distance from the ceiling to the device and the distance from the devices to the walls should be followed. By default, the distance from the installation to the ceiling cannot be less than 50 mm, and to the wall 100 mm.

Select installation method: wall, ceiling.
Make markings for mounting brackets according to the location of the device and recommendations for minimum distances to barriers (walls, ceiling).

If you need to install a thermal curtain on suspended ceiling, then pay attention to the operation of the ventilation system, which can become a significant interference in the operation of the installation.
Drill holes and secure the mounting brackets well.
Move the curtain towards the fastenings so that the set screws fit into the corresponding grooves.

Some models do not have mounting brackets. For wall mounting, standard holes are made in the body of such devices. To mount the device, drill a hole, insert plastic stopper and screw the screw into it. Then put the device on such mounts.

Instructions for connecting the device

Most air curtains are equipped from the factory with a connected cable with a Euro plug. Such installations only need to be plugged into the appropriate outlet. Before turning on, you must set all switches on the device to the Off position. or OF.

There are installations (usually more powerful) that are equipped with a wired remote control remote control. You should know that the remote control should be installed in a place where there is a lack of hot air from the veil.

There are air curtains that are not equipped with a power cable. To find out how to connect this type of air curtain, you should consult a qualified electrician or do the connection yourself.

To do this, you need to remove the installed heat curtain from its mountings.
Unscrew the casing screws and dismantle it.
According to the diagram given in the technical documentation for the device, connect the cable to the terminal box.
Close and screw the device casing.
Connect the cable to the Euro plug or to the electrical panel via a circuit breaker.
Install the device on standard mountings.
Check that all switches on the device are turned off.

Only after this can you make a test run by turning on the corresponding switch on the installation, after first applying voltage from the panel.

Electrical installation work should only be carried out by a qualified electrician with appropriate permission to work. If you ignore the safety rules, you risk getting an electric shock.

The most basic purpose of a thermal curtain is to prevent cold, frosty air from entering the heated room during entry and exit, or opening the door. In addition, such a curtain is able to protect the room in which the air conditioning system operates in order to lower the air temperature during hot periods.

In essence, thermal curtains are special equipment that is endowed with sufficient simple principle actions. During operation, air enters a special channel, which carries out suction and is then blown out with sufficient high speed. As a rule, thermal curtains are able to serve rooms where the height of the doorway does not exceed 3.5 meters. Some models may be equipped with additional heating elements. As for the effectiveness of such devices, everything depends on the quality of the equipment, as well as on competently carried out installation work.

Equipment installation process

Typically, the installation of a thermal curtain is carried out in rooms characterized by high traffic, when in the process of quite frequent opening of doors, streams of street air masses immediately enter the room, causing discomfort and drafts that are detrimental to health.

It is recommended to leave the installation process of the thermal curtain to professionals. Only qualified installers are able to install and connect the device as competently as possible. As a rule, the company that sells such equipment also offers installation services. Qualified specialists Before installation, the devices must be checked for integrity, and the equipment must also be in full compliance. Typically, the kit includes elements such as brackets, which make it possible to direct air flow in a certain way. Installation can currently be done in two ways - horizontal and vertical installation.

Horizontal installation of the curtain

Most popular on this moment is horizontal installation veils. This is based on the fact that the equipment is mounted above a door or window opening. In this case, the curtain should be selected solely taking into account that everything fully corresponds to a certain width of the opening; it is also allowed if the width slightly exceeds this figure.

As a rule, for all models certain installation height parameters are provided, therefore, in order to ensure maximum performance benefit, the device simply needs to be positioned in such a way that there is full compliance established rules. Horizontal method ideal in a situation where the door opens into the room, in this case the equipment will protect the room from the penetration of air from the street.

Vertical installation of the curtain

If the doorway in the room is very high, then the horizontal installation will not be able to properly ensure air flow along the entire length. It is for this reason that it is most advisable to use the method of vertical installation of the curtain. In this case, the equipment is mounted on the side of the opening; this is the only way to ensure a continuous flow of air across the door or window, while preventing drafts at floor level.

The horizontal and vertical models are practically no different in their principle of operation, but their installation must be carried out strictly in accordance with their intended purpose. For example, if you connect a horizontal thermal curtain vertically, after some time some problems may appear, even breaking down the entire system as a whole.

The process of connecting a thermal curtain

As a rule, the curtain is sold with a flexible cable, and there is also a plug that is equipped with grounding. If a stationary connection is made, that is, without a plug, then it is worth carrying out this process through a central switch with a gap of air, with a parameter of more than 3 mm. The connection of such a curtain must be carried out by an electrician who has a high professional level and is able to comply with all mandatory regulations.

During the installation process, special types of wires are used. At the point where the cable enters the equipment, special sealing rings are used, which are designed to provide high-quality protection.

Features of the thermal curtain

Before connecting a thermal curtain, it is worthwhile to qualitatively balance the working process of the ventilation system in the room, since different pressure differences can have some impact on the operation of this equipment.

It is worth installing thermal curtains as close to the openings as possible, and also carefully taking into account the fact that the width of the flow must completely correspond to the dimensions of the doorway.

Also, specialists must install equipment strictly from the inside of the room. WITH external installation produced only for the purpose of protection against overheating freezer. The speed of movement and direction are adjusted during the installation process, and it should be directed towards the exit to the street.

Main stages of installation of a thermal curtain

The process of installing a thermal curtain consists of several main stages. First you need to drill the special holes that will be required to attach the equipment. The equipment is mounted on special mounting brackets, maintaining a distance of 600 mm on average. Such brackets are attached to the surface of the walls in the lower and upper positions.

The thermal curtain must be positioned in such a way that its mounting screws fit exactly into the grooves of the brackets. Once the screws have been verified to be in the correct position, they are carefully tightened. Such a curtain can be mounted on a suspension, but for this purpose a certain position of the mounting fasteners will be required. If the curtain is installed on special floors, then holes are made in the panel. As for the installation method, it is selected strictly depending on the type of curtain purchased, as well as the characteristics of the room.

In the process of installing such equipment for air curtains, it is worth paying special attention to the special direction of air flow, as well as the speed of their movement. The curtain must be installed so that air currents those entering and leaving did not create barriers for each other.

The specialists who carry out the installation processes carefully study the technical documents on the equipment, and also familiarize themselves with all attached instructions provided by the manufacturer. As for the installation features, they can be completely different, and this factor must be taken into account. Almost all modern thermal curtains can be installed exclusively in a horizontal position, with air being pumped strictly from below. In a situation where it is necessary to install a thermal curtain over an opening that is quite wide, several devices can be placed simultaneously, but close to each other.

Equipment such as a thermal curtain does not allow cold air from the street to penetrate into the room. Not only the efficiency of its operation, but also its operating time directly depends on how well the installation is carried out. If you select the equipment correctly and install it correctly, the curtain will create comfort and coziness in the room for a long time.
