Air thermal water curtain. Choice of air curtain with water heating for a warehouse. The principle of operation and installation of water thermal curtains

Thermal water vertical curtains are becoming increasingly popular when creating a high-quality and practical system for protecting door, entrance or gate openings.
One of the main advantages of such curtains is that they are vertical, which means that the force and speed of the horizontal air flow is uniform across the entire width of the doorway, unlike horizontal ones, in which the air flow at its lowest point somewhat loses its temperature indicators. Vertical curtains are installed on the side of the door, if the opening is not very wide, then you can install the curtain only on one side, and if these are industrial doors or doors of a production warehouse, then it is recommended to install vertical curtains on both sides of the doorway.

An indisputable advantage is the connection of the water curtain to the hot water supply system, so the electricity in this case is used ONLY for the operation of the fan. This means that electricity consumption is significantly reduced. Therefore, if you need to install a powerful curtain for industrial use, it is recommended to use a water thermal curtain that can operate at full capacity, and you will not worry about the load on the power grid and the number of kilowatts consumed.
In summer, such a water curtain can operate without being connected to a hot water supply 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.

As a result, despite the limited assortment, the Tropic X series demonstrates quite decent functionality and performance, which can be purchased for a reasonable price.

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 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 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 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 several times less expensive, but do they bring the desired effect? After all, 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 exit 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.
