Air thermal water curtain. Thermal curtain with water heating. Thermal curtains brand Tropic

A water thermal curtain is one of the types of climatic equipment designed to maintain a certain temperature in a room by preventing the leakage of warm air to the outside and cutting off cold outside air. This is a kind of thermal barrier that separates the room and the outdoor space with a flat stream of air, which is supplied under pressure.

Equipment that creates a thermal barrier is designed for installation in the plane of a door or gate opening in places with a large flow of people: in industrial workshops, public and residential buildings, shopping centers, warehouses, restaurants.

How a water heating system works

The principle of operation is quite simple: a radial fan directs an air flow to the opening - a kind of barrier through which warm air cannot leave the room, and cold air cannot penetrate inside.

The fan turbine is located along the entire device - this ensures efficient and uniform supply of hot air, which is pumped through the case. The air movement scheme is as follows: cold air is taken from the floor, blown through the heating circuit and given out in a hot jet parallel to the plane of the doors or gates.

The engine is attached to the side. If the length of the turbine exceeds 0.8 m, then the engine is located in the central part, and additional small turbines are installed on the sides.

The cut-off curtain heats up during the passage of air through the water heater. The water curtain requires central heating or a hot water network to operate.

The complete assembly looks like this:

  • heat exchange mechanism;
  • control system (electronic);
  • fan;
  • frame;
  • guide blinds;
  • brackets;
  • side panels and covers.

Classification

Water thermal curtain can be presented in various models designed for use in buildings with certain conditions. Classification of equipment is carried out according to various characteristics, including:

  • by appointment: general, for car washes;
  • by air flow: small, medium, large;
  • by location: vertical, horizontal;
  • according to geometric parameters: according to the section of the body - round, elliptical, rectangular, others; according to the structure of the nozzle - semicircular, straight.

Control

Water curtains are controlled by two switches, which can be mechanical or electrified.

The fan - which can be two speed - and the heating elements are switched separately. The control system can be equipped with additional 2 (3) step heating power regulators. If the fan is two-speed, then its speed is also controlled by the remote control.

If a thermostat is installed, the equipment may automatically turn off when the set temperature value is reached.

The control panel, depending on the model, has varieties:

  • built-in - for small curtains that are installed above door or window openings in small rooms;
  • wired - in large rooms where the control of the built-in button is difficult, and the remote control can be placed in a convenient place.

In warehouses and hangars, limit switches are used that bring the system into operation only if the door or gate is open.

Unique System Benefits

Water thermal curtains have such design features that give them a number of advantages over electric heating devices:

  • Less energy consumption with equal heat transfer. Cost savings can be up to 30%.
  • Possibility of installation in case of technical difficulties: insufficient power supply, high opening height (up to 12 meters).
  • Convenient Maintenance due to the simplicity of the design.
  • Maintaining a stable temperature in the room and equalizing the temperature difference in the ceiling area and at the level of human growth - this makes it more comfortable for people to stay in the room and creates favorable conditions for storage of any goods.
  • Neutralization of drafts, which leads to a decrease in the risk of colds.
  • Protection against ingress of insects, small animals, dust into the building.
  • Possibility of use as an air conditioner if the coolant circulation system is turned off.

The water curtain creates additional convenience at car service stations, car washes, checkpoints and catering points, because thanks to it the front door can always remain open. In addition, it not only creates insulating protection, but also carries the function of a heater on the threshold of the warehouse.

The scope of its application depends on the functionality of the equipment: from air shielding of warehouses and hangars to saving the interior of an office or shopping center from street dust.

Choice of water thermal curtain

Water curtains are needed, first of all, for air isolation of the inside of the room from the outside air. Productivity, that is, efficiency - this is main characteristic equipment.

Important are other criteria that you need to pay attention to when choosing a particular model:

  • type of room;
  • is there a vestibule;
  • what are the usual weather conditions;
  • for what purpose the veil is acquired;
  • desired type of installation;
  • control method;
  • dimensions (length) of the device necessary for high-quality overlapping of the opening;
  • what power is needed - this factor is most important if it is necessary to heat the room;
  • performance affecting the airflow rate and unit height.

Thermal curtain market

The most famous companies on the Russian market are:

  • "Ballu" (international holding) - products with minimal energy consumption. Among the models: horizontal BHC-H20-W45, BHC-H10-W18; vertical: Stella BHC-D25-W45, StellaBHC-D20-W35.
  • "Frico" (Sweden) - excellent design, great quality, versatility, but high cost. Model options: AR3515W, ADCSV25WL.
  • "Tropic Line" (domestic brand) - functional and efficient equipment at affordable prices. However, only a few models (for example, X432W, X540W) are industrial water devices, the rest are household.
  • "Teplomash" (Russian manufacturer) - products are reliable, easy to use, the cost is affordable.

Serial Russian models "Teplomash"

As an example, we can consider in more detail the serial models of the Russian manufacturer, Teplomash, in terms of thermal power:

  • . Here are the 100 series (opening: 1–2.5 m), KEV - P114E and P115E - with ceramic heaters with a PTC self-regulation effect and temperature controllers.
  • Medium power. In that model range series can be seen: 200 (opening: 2–2.5 m); 300 (3–3.5 m) and ceiling series 300 (built into a false ceiling).
  • Interior. The 600 series is available in elegant vertical columns and illuminated horizontal elliptical or segmented versions.
  • Industrial thermal. Series 400 (opening: 3–5 m); 500 series (up to 6 m).

Heavy duty constructions - 700 series water curtain for openings up to 12 meters high. Usually made to order for special equipment (hangars for aircraft and helicopters).

Installation of models of these series can be both vertical and horizontal - on the side of the door or gate. If necessary, it can be installed on both sides of the opening.

In all designs, the shell provides a degree of protection - IP-21 (against vertical drops and large particles). If the room is dominated high humidity, IP-54 degree of protection can be provided on request (for some models).

Installation

Installation of a thermal water curtain is time-consuming and requires the involvement of a specialized company - this will provide warranty service and subsequent services.

The costs required for the installation of equipment are fully paid off during operation due to high power, effective work and low maintenance costs.

There are 3 ways to position the system:

  1. Horizontal installation - above the opening of the door or gate.
  2. Vertical installation - on the side of the entrance opening.
  3. Concealed installation - placement behind the suspended elements of the ceiling of the built-in unit with the output of the cut-off flow through the air supply grilles.

The height of vertical water curtains must be at least ¾ of the height of the heated opening.

Horizontal curtains should cover the opening across the entire width. Failure to follow this rule will result in a failure in the air barrier.

Only standard brackets recommended by the manufacturer may be used to mount the system. The distance from the surface (for horizontal installation - from the ceiling, for vertical - from the wall) must be at least 0.3 m. Otherwise, the air intake of the equipment will be difficult, which will lead to a decrease in productivity.

The equipment is connected to the central heating or hot water supply system using quick-release parts. If necessary, due to the type of room to be isolated, a pump is installed that enhances air circulation to enhance heat transfer.

Thanks to the generation of an air insulating barrier, water curtains create a special microclimate in the premises. for various purposes: from offices to warehouses and hangars. Such structures require energy costs, but the overall energy consumption is reduced by protecting the building from freezing. Water curtains can be considered as an optimized source of energy, working due to circulation hot water in the general heating system.

When cold outdoor air penetrates into a heated room, several significant problems are created at once. Firstly, the cost of heating increases sharply, as they say, heating the street. Secondly, these feelings are far from pleasant, which, moreover, can lead to poor health. Such problems can be solved by installing a thermal curtain, it will create a reliable barrier to cold air.

Depending on the heat source used, air-thermal curtains are divided into electric and water. The latter compare favorably with their efficiency, using central heating hot water as a heating element. These devices are widely used due to several advantages at once:

  • protection of the premises from cold air and heat loss;
  • protection of people indoors from drafts;
  • additional space heating in winter;
  • support for cool air-conditioned air in summer;
  • additional barrier against dust, insects, exhaust gases from the outside;
  • low operating costs, unlike electric thermal curtains.

The principle of operation and installation of water thermal curtains

The principle of operation of the device is as follows: the fan inside the device creates a high-speed air flow, as a result of which warm air does not leave the room, and the outside one does not penetrate into it. The heat source of this air curtain is hot water from the central heating system.

The installation of this unit requires large financial and physical costs, but all this pays off in full later due to low costs and high power. Devices of this type can most often be found in industrial enterprises, but it is also indispensable in other trade or public catering premises with a large flow of visitors.

Installation is carried out directly in the area of ​​the entrance door: horizontal curtains - above the door, vertical curtains - on the side of the entrance opening. Please note that the vertical curtain should not be less in length than the height of the doorway.

The main element of the water thermal curtain

Such an element is a radial fan, which creates the necessary air flow at high speed. Such a single turbine should be located along the entire length of the thermal curtain. The fan creates a uniform air flow, and its motor is mounted on the side of the device.

But there are units with an engine in the center, and turbines are located on the side of it. The reason for this may be the high cost of manufacturing turbines with a length of more than 70 cm. Of course, such simplified curtain designs are many times less expensive, but do they bring the desired effect? Indeed, in the central part of such a device there is no necessary high-speed air flow, and this leads to a decrease in the main protective function of the thermal curtain.

Water curtain control type

Water curtains must have at least two switches: one for the fan and one for the heating element. Additionally, two- or three-stage heating power regulators, a switch for the second fan speed, and a thermostat for maintaining the set temperature can also be mounted.

Instrument control depends on the selected model. There is a mechanical control built into the air curtain body, as well as remote control. However, the first option is used only on small models designed for installation on door and window openings. standard sizes. This situation is easily explained: the buttons on the case can only be reached from an arm's length, and high-power water curtains installed, for example, in warehouses and workshops, are more convenient to control from the remote control.

It is very convenient to use a limit switch in the curtain design. It activates the thermal curtain only when the gate or door is open. Such a device is also good for its economy of use.

Criteria for choosing a thermal curtain

Choosing water curtain you need to pay attention to the following parameters:

  • instrument length;
  • curtain power;
  • device performance.
  • installation method;
  • device control type.

The performance of the device affects the speed of the air flow, and accordingly affects the maximum height of the installation. For the sake of financial savings, it is not worth taking a water curtain with a lower capacity than necessary. Incorrectly selected veils will not bring the desired effect.

Power is also the main parameter when choosing a thermal air curtain, especially if space heating by air heating is enabled in the device function. On average, to heat a room of 10 m², you need a device with a power of 1 kW. But it should be clarified that the air at the outlet of the thermal curtain will never be hot, since the heating elements have a high blowing speed.

Curtain length different models and manufacturers are 60-200 cm. For standard doorways models with a length of 80-100 cm are well suited. In general, the choice of the length of the water curtain depends on the width of the opening: either equal to it or be slightly larger. Such a rule must be observed so that the air flow of the curtain can completely block the access to outside air.
