The air curtain at the front door: the types and principle of operation

The whole complex Thermal insulation work It may not be feasible if the heat will escape through the house the front door. Rectify the situation helps a special device: the air curtain at the front door. We offer to meet with the principle of work, varieties and features of operation of such equipment.

Platten - what is it

Considering the existing types heatersYou can see the thermal curtains. What is it can be understood in functional characteristics of the device. It is installed directly above the front door and prevents cold air from outside. At the same time, the air curtain - a heaterWhich allows to heat the air in the room.

Attention! Setting the air curtain allows to reduce by one third the cost of heating.

The air curtain at the front door: the working principle and main technical characteristics

According to its constructive performance air curtain close to a household conditioner with characteristic elongated rectangular shape. Openings in the upper and lower housing portion are used to create air flow. Air intake is performed through openings in the upper part. Inside the ventilator ensures the formation of an air flow directed downwards. Located around the heat exchanger unit heats the passing air flow, which extends outwardly through the openings in the bottom of the unit.

In the selection of thermal curtains should be guided by technical specifications, which should include:

• device performance, showing how the amount of cold air may be heated with it;
• dimensions;
• attachment type;
• degree of protection;
• air curtain power.

Varieties of curtains for the house on the location and type of installation

When selecting the air curtain for home, be aware that these devices can be variously positioned relative aperture and have a different type of installation. By arrangement of devices can be:

• horizontal. The classic version with the highest circulation. They are mounted directly above the front door or window;

• vertical. This embodiment is overdue at impossibility or irrationality horizontal installation model. Vertical products can be placed on only one side of the front door or on both sides;

• universalAdmitting the horizontal and vertical mounting.

By type of installation division is made on the model, which are mounted directly on the wall, and assemblies, embedded in the ceiling or wall. The latter option is relevant in the regeneration areas, to which the registration of increased requirements.

Types of household curtains on the presence and type of heat exchanger

Design household curtains might differ. Manufacturers offer devices equipped with various types of heat exchangers, as well as without them. We offer to meet with the existing species and their distinctive features.

Electric air-heat exchanger for the air curtain

The most efficient model. Easily installed and maintained. Permissible installation not only on the front doorBut also in any other place. Allow to smoothly adjust the temperature of the outgoing air.

Most modern air curtains equipped with tubular eletronagrevatelyami (TANS). Cheaper counterparts - semiconductor heaters (RTS). They have the function of self-control of energy consumption and temperature to optimize energy costs.

Attention! The air curtain at the front door 220 is capable of becoming the best option for private homes and public buildings.

Water air curtain at the front door

Any electric heat exchanger is characterized by high operating costs. Water air curtain at the door, from this standpoint, is preferred as it can be connected directly to heating circuit. Efficiency of service and lack of harmful effects on the environment - important advantages of this type of devices. But by installing them in some cases refused because of the large size, the complexity of installation and increased requirements to the state heating system. At low coolant used as a risk of falling into shallow tubular device structure which can cause device failure.

"Installation water heat curtain should be performed in conjunction with a filter or initially choose a model, complete with this element."

Models not equipped with a heat exchanger

Such devices are relevant in situations where it is not necessary to produce additional heating of air. Scheme thermal RV series curtain to protect inner space from street dust, dirt, insects, preventing leakage conditioned air outside the home. most of these devices are installed in the territory of industrial plants, acting as a zoning member large room or freezer protecting against ingress of external warm air. Other applications availability.

How to choose a veil of heat power

To install the unit coped with the task assigned to it by its power must be appropriate. Thermal devices are divided into the following series:

• RS;
• RM;
• RT.

The first set has a limited field of application. With its help, you can protect only a relatively small aperture, such as a window service at the box office or street stall. In domestic purposes, they practically do not apply. Characterized by low productivity. Used for apertures up to 1.5 m width and 0.8 m.

Power air curtain series RM is sufficient for installation over standard doorways, having a height of 3.5 m. May be mounted above the door. This series is the most popular of a large number of consumers. Often it comes with a remote control or special remote unit, simplifying the management process.

Series RT is the most powerful. With it can protect aperture height of 7 m. This is a suitable option for gatesInstalled in different rooms, such as storage or production.

As the air curtain installation is carried out

Mounting the air curtain should be carried out in accordance with manufacturer's instructions. Works are carried out in the following sequence:

• chosen place of installation with the air curtain into account its structural characteristics;
• base counting is performed;
• mounted brackets;
• mounted equipment;
• the control unit is mounted;
• connection to the electricity system and security elements;
• System Health Validator.

"The installation of some models will need to remove the front panel during installation of the control unit."

Features connecting curtains

Typically, the kit includes a flexible cable and plug with ground. When connecting the stationary platten is connected via a central switch. Necessarily leave a gap of 3 mm. The work can only be done by a professional.

Attention! To connect, use a special type of wire.

Terms of Service air curtains

To prolong the life of the equipment, should follow the manufacturer's recommendations for maintenance curtains. Each month, should produce a visual inspection device, check the quality of attachment, no visible defects, test operating current and voltage. The apparatus requires monthly cleaning housing, air filters, shutters input from the accumulated dirt and dust.

Quarterly via specialists controlled quality of threaded connections, pins are stripped, inspected fuses and lugs. If necessary, change the damaged elements with new ones. Controlled fan status.

Every six months, changing the operating mode in connection with the change of season. Implemented pneumatic cleaning base nodes including the heat exchanger. Once a year, the heat exchanger is cleaned with a special chemical composition. Controlled by the bearings of the fan motor.

Nuances repair curtains

More often than not establish the cause of their failure is difficult enough forces. For the diagnosis may require professional help. Often results in damage to the equipment failure to comply with the manufacturer's recommendations on the mode of operation of thermal barrier, which causes it to overheat. As a consequence, you may need replacement relay, The heating element, switch or electrical contacts.

Attention! Not always repair curtains can be made in the places of their installation.
