Water thermal curtains with a sensor. Choice of air curtain with water heating for a warehouse

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. You can solve such problems by installing a thermal curtain, it will create reliable barrier for cold air.

Depending on the heat source used, air- thermal curtains divided into electric and water. The latter compare favorably with their efficiency, using hot water central heating as a heating element. These devices have become widespread 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 is air curtain is hot water from central heating.

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 most often found in industrial enterprises, but it is also indispensable in other commercial or Catering 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

This element is a radial fan that creates the necessary air flow. 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 several 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 at 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 open gate or doors. Such a device is also good for its economy of use.

Criteria for choosing a thermal curtain

When choosing a 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 exit of the thermal curtain will never be hot, since heating elements have a high flow rate.

The length of the curtain of different models and manufacturers is 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.

An economical option for HVAC equipment are thermal water curtains. They protect the room from the cold, heat it and prevent penetration from external environment unwanted particles. The heating element is the central heating system with hot water.

Air-water curtains are mounted in residential buildings and installed in non-residential premises. Equipment can be placed:

• Above the doorway
• Above the window
• On the sides of internal floors and passages.

Kinds

Water thermal curtain is divided into the following models:

• With horizontal (vertical) mounting. These curtains are used for gates. To cover the entire opening area, it is recommended to install vertical models. They create a directional lateral airflow,
• Ceiling. To hide risers, channels and the equipment itself, products that are built into suspended ceiling,
• Special design. Created in the form of a segmented body. Such models are suspended from the ceiling or placed vertically on the floor.

The Teplovent store sells products from such manufacturers as:

Design

The elements of the equipment are:

• Heating element,
• Nozzle,
• electric motor,
• Fan.

The functions of the heating element are performed by a two-way heat exchanger. It is created from copper pipes, which are equipped with lamellar aluminum fins. Through the nozzles that exit the housing, water is supplied to the heat exchanger.

Its connection to the heating network is implemented using flexible corrugated pipes. AT winter period possible shutdown hot water. Therefore, the devices are provided with a drain of water. The water thermal curtain, if properly installed, is free from corrosion. Its body is made of special materials. The insulation of internal elements is also made of special materials.

Operating principle

The equipment uses an air stream that is heated by the thermal energy coming from the heat exchanger. Electricity is consumed only for the rotation of the fan and comes from a 220 V network.

The blowing of thermal curtains and heating (partial, maximum) depend on the functioning of the fan. The water curtain is controlled by a remote control.

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 can not leave the room, and cold - to get 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 flow pattern 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.

Construction in complete assembly as follows:

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

Classification

The 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 shape, other; 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, there may be automatic shutdown equipment 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.

Warehouses and hangars use limit switches 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 preserving 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

On the Russian market the most famous firms:

• "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) - great design, excellent 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 serial models in more detail in terms of thermal power. Russian manufacturer- firm "Teplomash":

• . 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 special equipment(hangars for airplanes 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. Distance from the surface (at horizontal installation- from the ceiling, with a vertical - from the wall) must be at least 0.3 m. Otherwise, the air intake by 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 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, operating due to the circulation of hot water in common system heating.

One of the main types climate technology, providing a reduction in heat loss of the building, a water thermal curtain capable of operating in the presence of a central heating network or hot water supply.

Installations of this type are successfully used in the absence of the possibility of installing electrical units in residential and amenity premises, production shops, office and shopping centers.

The principle of operation of a water thermal curtain

Modern air curtains, water curtains are an improved air heater that provides the creation of a cut-off flow in door and window openings of various sections. The air flow is created with ventilation unit, which may have different design. The cut-off curtain is heated when air passes through a water heater, which is connected to the hot water supply network.

This design has a number of advantages compared to traditional electric heaters:

The use of thermal curtains in various modes allows not only to prevent the penetration of cold air into the room in winter. When the coolant is turned off, it works effectively even in summer heat in addition, such devices prevent the penetration of insects and small animals into the serviced premises.

Classification of water thermal curtains

Specialists classify thermal water curtains according to a number of technical characteristics. Moreover, each modification is most effective only for protecting premises under certain conditions.

According to thermal power, they distinguish:

• Household (local) thermal curtains, which can be used for installation on small openings. Most often, such installations can be found on the windows of stalls, small retail outlets, cash desks. They are also used as window curtains in residential premises.
• A thermal curtain of medium power is effective at an opening height of up to 3 meters. This category includes most of the modifications used to protect the entrances to shopping and office complexes.
• To protect the opening at a height of up to 7 meters, powerful thermal curtains are used. Most often they can be found in production and storage facilities, logistics centers.
• For large openings, heavy-duty curtains are used. Basically, such devices are produced according to individual orders on the basis of specially developed projects for the energy supply of buildings.

According to the method of installation, horizontal and vertical thermal water curtains are distinguished. Most often, horizontal modifications are used, which are mounted above the doorway. The use of several such units allows you to protect even very wide openings. When installing vertical curtains, they are mounted from one or two sides of the entrance, while in height they must cover at least 2/3 of the opening.

In some cases, built-in curtains are used, placed behind suspended structures ceiling. At the same time, only the air-supplying decorative grilles remain visible.

The most popular brands of thermal water curtains

The market is widely represented by products of both domestic and western manufacturers. The following brands are most in demand:

Domestic water thermal curtain "Teplomash"- the most famous in Russia trademark. This manufacturer is one of the few that has established the production of curtains for openings with a height of 12 meters or more.

The company's products are reliable, easy to manage (automated systems are used to simplify the choice of the required mode of operation).

The advantages include the affordable cost of thermal curtains "Teplomash". So a unit for an opening up to 15 meters can be purchased for 80-100 thousand rubles, and small household models for 15-20 thousand rubles.

Frico Swedish water curtain belongs to a fairly expensive price segment.

The average cost of a model with a capacity of 800-900 cubic meters of air per hour is about 140-150 thousand rubles.

Basic rules for installing water curtains

For installation of air curtains, it is necessary to use only standard mounting brackets provided by the manufacturer. At the same time, it is necessary to maintain a distance of at least 30 cm from the ceiling or side wall. Failure to comply with this requirement may lead to a decrease in the efficiency of the unit due to obstructed air intake by the unit.

When installing horizontal curtains, it is necessary to select a kit that covers the entire width of the opening, otherwise certain areas of dips in the created drip will be observed.

Thermal water curtains manufactured by Teplomash are modern compact equipment with a water source of heat, which is installed above door and gate openings to provide mixing and sliding protection of openings. Air curtains with a water source of heat are designed to effectively protect premises from cold outdoor air. In addition, they can significantly reduce heating costs, since sliding curtains cut off and heat cold air from the street, and mixing curtains only heat cold outdoor air before supplying it to the room.

Design features and advantages of water curtains

Air curtains "Teplomash" products of full factory readiness. Almost all Teplomash curtains can be installed both horizontally and vertically. Curtains are produced different lengths, but if the door or gate opening is wider or higher than the length of the curtain, but you can put several curtains in a row.

The water horizontal thermal curtain is fixed on a solid ceiling structure with threaded rods or on the wall - using the brackets included in the kit. To ensure maximum performance, it is essential to ensure correct location curtains in relation to the doorway. Obstacles in the way of the air flow from the air curtain significantly reduces its efficiency.

Thermal air curtain with water heating, installed vertically on one or both sides of the doorway, is mounted using standard brackets directly to the wall or to the floor on a special bracket.

Thanks to the use of hot water as a heat carrier, a water thermal curtain on front door is economical. In addition, the curtain allows:

• keep the front door open, which is important for shops;
• create an air barrier that prevents cold outdoor air;
