Thermal curtains with water heating. Thermal water curtains: principle of operation, installation methods, types. Design features and advantages of water curtains

Thermal water curtains belong to the class of climate technology. With their help, a steady directional flow of hot air is created.

The direction of the heated air jet can be vertical or horizontal (parallel or perpendicular to the floor).

The main source of thermal energy is hot water. A thermal curtain with a water source of heat can be connected to a centralized hot water supply or water heating system of a building.

Units of this type are economically advantageous to install in rooms where there is not enough electrical power.

The thermal curtain must correspond to the characteristics of the object on which it is going to be used.

The main selection criteria are:

• performance: the indicator is characterized by the volume of air passed through the thermal curtain.

For example, for installation on a doorway measuring 2x1 meter, it is necessary to use a curtain with a throughput of 800-900 cubic meters. m/hour.

If a unit of lower capacity is installed in such an opening, then only its upper zone will be heated. And through the lower part of the opening, cold air will enter the room;

• dimensions: the size of the unit must exactly correspond to the width of the opening in which it will be installed;
• centrifugal fan (turbine) length: this element must be equal in length to the length of the entire thermal curtain;
• air flow rate: for low openings, a low flow rate of heated air is sufficient.

Large openings require high speeds. Often it is necessary to mount several curtains in large openings;

• the presence of a thermostat: built into the design of the curtain, it greatly facilitates its operation, since its task is to maintain a constant temperature in automatic mode throughout the entire period of operation of the device.

By power veils are divided into:

• household: form a narrow stream of warm air. Are applied to protection of windows of booths, cash desks. Can be used in a residential area.

They are installed above window openings in order to reduce heat loss and protect against drafts. In small rooms, household curtains serve as an additional source of heating;

• medium: used in openings, the height of which does not exceed three meters. These settings are the most common.

Their task is to reduce heat loss with open doors and protect people inside the room from drafts;

• large: are used in small workshops with medium-sized doorways up to seven meters high.
• heavy duty: installed in openings up to 12 meters high. Such powerful installations are used in warehouses, production workshops, large stores.

A thermal curtain can also be used at home, but there are other solutions. An interesting option that helps solve the problem of drafts and temperature changes is a warm floor. Read a detailed article about the device, and much more, to learn about all the advantages and disadvantages of such a solution.

When extracting water from a well, a pumping station is needed to maintain a constant pressure in the system. Read everything about these devices, including the Marina pumping station, the most useful and up-to-date information.

Classification of air curtains by type of protection ^

According to the type of opening protection, air curtains are divided into:

• mixing;
• sliding.

Mixing thermal curtains work as follows: in the zone of their action, cold air is mixed from the street and warm air coming from the installation.

The jet pressure of such devices is small, but a high power of the heating elements is required.

Sliding installations are characterized by a high pressure of the air flow, due to which outside air does not enter the room.

Most modern models of thermal curtains can operate in both mixing and sliding modes.

Classification of thermal curtains by installation method ^

According to the installation method, the curtains are divided into:

• horizontal: mounted above the entrance into the room. The main requirement for such an installation is the effect of the device on the entire width of the opening;
• vertical: established on the sides of the opening. At the same time, the height of the thermal curtain must be at least 2/3 of the opening height;
• embedded: are placed behind the ceiling. Only the air intake and air distribution grilles remain visible. This method does not affect the power of the curtain in any way..

The device and principle of operation of a water thermal curtain ^

A thermal curtain with a water source of heat consists of:

• durable steel case with a protective coating applied to it;
• two-way water heater.

Modern air heaters are a structure made of a copper pipe with aluminum lamellar fins stacked on it.

The air heater cannot be dismantled. The coolant (hot water) enters it and is discharged from it through pipes located in the side of the structure.

The air flow is provided by axial fans. The fan motors have several speeds.

Adjustment and control of the air curtains is carried out either with the help of an external or remote control panel (depending on the brand and model of the device).

Air is taken in through the perforated panels of the housing, and ejected through a slit-like nozzle located at the bottom of the unit.

In the engine compartment of any brand of air curtain there is an earth bolt, which is connected to the terminal block through internal communication.

To ensure normal operation of the air curtain, a water filter must be installed at the coolant inlet.

Many models are equipped with a mixing unit that serves to control the flow of the heat carrier (and, consequently, the air temperature at the outlet of the air curtain).

The principle of operation of a water thermal curtain is no different from the operation of devices using other types of heat carriers:

The fan takes air from the room, drives it through the air heater and directs it with a powerful jet downwards (in case of horizontal installation) or sideways (in case of vertical installation).

Installation rules for water curtains ^

Before proceeding with the installation of water thermal curtains, a diagram is drawn up for connecting the installation and pipelines to the heat carrier source (central hot water supply system or boiler equipment).

The simplest circuit consists of the following elements:

• thermal curtains;
• coarse water filter;
• crane - air vent;
• shut-off valve;
• check valve;
• circulation pump (when connected to boiler equipment).

For the operation of a thermal water curtain, a constant temperature of the heat carrier is required. In a large room, a good solution can be with a capacity of tens of liters per minute. Read all about these devices in our article.

And another interesting article that describes pumps for water heating, their characteristics, prices, and so on, is located, make the right choice!

After the scheme has been drawn up, proceed to the installation.

The brackets on which the air curtain is installed are fastened evenly across the entire width of the opening, taking into account that the distance from the edge of the air curtain to the ceiling must be at least 30 cm (if the air curtain is mounted vertically, then such a distance must be maintained between it and the wall).

The brackets are attached with anchor bolts.

The thermal curtain is attached to the brackets using standard bolts.

Since the ends of the connecting pipes are at the same level, an extension cord (up to 5 cm) is installed on one of them for convenience.

A quick-disconnect connection is packed on the extension cord (designed for quick installation and dismantling of the air curtain).

Through the shut-off valves, we connect the curtain to the coolant supply-return lines.
After checking the joints for tightness using pressure gauges, the installation can be started.

When planning the heating of any room, the dew point value must be taken into account. What is it and why is it so important - read our article!

Sufficiently pure water is necessary for long-term operation of a water thermal curtain. To solve this problem, you can purchase a main filter. What filters are best? Read about it, it's interesting!

Popular brands ^

There are several well-known manufacturers of water curtains.

"Teplomash" ^

NPO Teplomash holds the leading position in the domestic production of water curtains. The enterprise produces units with power from 2 to 230 kW.

Models designed to protect small openings cost:

• 100 W power - 16350 rubles;
• With a power of 150 W - 20850 rubles.

The cost of Teplomash products designed to protect openings with a height of 3 to 5 meters is from 24 to 38 thousand rubles.

Super-powerful curtains with a jet length of 15 meters cost about 80 thousand rubles.

Tropic ^

This is another Russian company that successfully competes with other manufacturers of thermal water curtains. The cost of products of this brand is practically no different from the prices of Teplomash.

Frico ^

Swedish-made water curtains, in addition to excellent quality, also have an excellent design.

But their cost differs markedly from the cost of Russian-made devices. So, a small curtain with a capacity of 800 cubic meters. m / hour will cost the buyer 2000 euros.

ballu^

Water curtains of the Ballu brand are designed for openings of various heights - from 2.5 to 4.5 meters. All devices of this brand are universal: they can be mounted both vertically and horizontally.

Approximate cost of curtains brand Ballu:

• installation height 3.5 meters, power 11 kW - 18 thousand rubles;
• installation height 4.5 meters, power 18 kW - 2 thousand rubles.

Interior curtains designed to protect entrances to offices and other premises with high requirements for appearance are much more expensive - from 180 thousand rubles.

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 of 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 the gate or door is open. 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 outlet of the thermal curtain will never be hot, since the heating elements have a high blowing speed.

The length of the curtain of different models and manufacturers is 60-200 cm. Models with a length of 80-100 cm are well suited for standard doorways. 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.

Prices and reviews for popular models of thermal water curtains

The main manufacturer of air curtains with water heating is Ballu. The models offered by this company will satisfy various buyers. The devices available for sale are designed for home and industrial use, with mechanical and automatic control, horizontal and vertical installation or universal models.

As for the prices for the series for standard openings with a height of no more than 3 m, here the manufacturer Ballu offers a Ballu BHC-8W device with a power of 8.7 kW for $ 140. The performance of the device varies from 1100-1400 m³ / h due to the possibility of switching speeds. Universal installation provides for horizontal and vertical mounting with spigot outlet both on the left and on the right side of the body. The model provides for a wired remote control.

With a sum of $340, you can purchase a Ballu BHC-36W device with a power of 34 kW, due to which the maximum installation height can reach 4 meters. Thermal curtain on water heating Ballu BHC-36W is equipped with a remote control, has three speed modes and a capacity of 2600-5000 m³/h. Also, the device assumes universal installation and connection to the heating system.

The thermal curtain protects the microclimate of the heated warehouse from the cold environment by generating an air barrier in front of the warehouse. Of course, such a system requires constant energy supply, but the total energy consumption of a warehouse equipped with a thermal curtain only decreases. After all, the air barrier prevents the room from cooling out, reducing the cost of heating the storage.

In addition, there are ways to reduce the energy consumption of the thermal barrier itself by optimizing how the air is heated. And a good example of such an optimized scheme is a water thermal curtain that heats up the air barrier due to the energy of the coolant circulating in the warehouse heating system.

Advantages of water-type thermal curtains

• Firstly, such curtains consume a minimum of energy, "feeding" from the thermal circuit of the warehouse heating system.
• Secondly, such curtains stabilize the temperature in the protected room, creating ideal conditions for storing the most "capricious" inventory items.
• Thirdly, water curtains not only protect, but also heat the warehouse entrance.
• Fourthly, thermal curtains eliminate the appearance of drafts, improving the working conditions of warehouse personnel.
• Fifthly, such curtains can be modified by turning from a heater into an air conditioner. Moreover, such a transformation is carried out by disconnecting the curtain circuit from the coolant circulation system in the heating system. After that, the curtain starts to work like a huge fan, conditioning both the warehouse entrance and the storage itself.

That is why the scope of water curtains can be the widest, extending from thermal shielding of the thresholds of overall warehouse openings to protecting the interior of a store or cafe from dust and insects.

How does a water heated air curtain work?

The thermal curtain with water heating works on the principle of an air convector. That is, powerful fans blow a stream of cold air - taken at floor level - through the heating circuit (outlet from the heating system). As a result, a dense jet of hot air is generated, directed parallel to the plane of the protected opening.

Moreover, the air flow of the curtain is formed by a special turbine - a radial fan that pumps air through the snail body. Therefore, water curtains are mounted either horizontally (in the lintel area) or vertically (on the side of the opening, occupying ¾ of its height).

The air curtain control unit can be either mechanical or electrified. The latter option assumes the possibility of automation of the air curtain control process. However, regardless of whether the water curtain is controlled by mechanics or electronics, this unit must regulate both the turbine speed and the heat transfer of the heating circuit.

The air curtain is started by a command from a remote or stationary control panel or a limit switch. That is, in the first case, the thermal curtain works constantly or during unloading and unloading of goods. In the second case, the start signal is the fact of opening the doors to the warehouse. Accordingly, after closing the opening, the air curtain turns off.

Choosing a water curtain for a warehouse

In the process of choosing thermal curtains, as a rule, the following criteria are used:

• Turbine dimensions (hull length).
• Device power.
• Air curtain performance
• The type of device control node.

In addition, the dimensions of the opening itself, the height of the lintel and the distance from the edge to the wall, which will determine the type of curtain (horizontal or vertical), may also have some influence in favor of choosing one or another model.

Moreover, the dimensions of the turbine must correspond either to the width (for horizontal curtains) or the height (for vertical devices) of the opening. Although usually the dimensions of the curtain fit into the size range of 0.6-2 meters, but if the opening is wider or higher, then devices with a longer body are selected.

The air curtain power is determined by the volume of the protected premises. Moreover, if for every 25-30 cubic meters of room volume there will be at least 1 kW of thermal power, then the curtain can also be used as a heater that heats the vestibule.

The performance of the air curtain is determined by the area of ​​the protected opening. Moreover, the main criterion for performance is the speed of the air flow. At the end (near the floor), it should be at least 2 m / s. It is this criterion that determines the power (performance) of the turbine, measured by the volume of air flow pumped in one hour. Moreover, one square meter of the opening area accounts for at least 350 m3 / hour of turbine productivity.

In a word, the choice of a curtain is a very complicated procedure. Therefore, in the absence of the practice of engineering calculations, curtains are selected according to the recommendations of manufacturers, focusing on standard models.

Popular models of water-type air curtains

Curtains of industrial type are produced by only a few manufacturers of thermal equipment. Moreover, the most notable participants in the market of industrial thermal curtains are the companies Ballu, Teplomash, Frico, Tropic.

One of the main types of HVAC equipment that reduces building heat loss is a thermal water 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 workshops, 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 using a ventilation unit, which can have a 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 also works effectively in the summer heat, in addition, such devices prevent insects and small animals from entering 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, mounted curtains are used, placed behind suspended ceiling structures. 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 trade mark in Russia. 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 operating mode).

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.

Experts attribute the traditional Swedish quality and excellent design to the advantages of this brand's equipment. These curtains are widely used for installation in shopping and entertainment centers.

International production holding Ballu produces a significant amount of climate equipment and units for heating. The corporation's production facilities are located in Eastern Europe and Asia.

Differs in the minimum power consumption. The company produces equipment for protecting openings of various sizes.

The average cost is about 20-30 thousand rubles. The product line also includes units that meet more stringent design requirements, although their cost significantly exceeds 100 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.

An economical option for HVAC equipment are thermal water curtains. They protect the room from the cold, heat it and prevent the penetration of unwanted particles from the external environment. The heating element is a 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 a false ceiling are suitable,
• 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 made of 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. In winter, hot water may be turned off. 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 warmed 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.
