Thermal veils have long been used to regulate the microclimate by protecting and distributing temperature zones in rooms for various purposes. The principle of operation of this equipment provides the opportunity to combine such operational qualities as energy saving, performance and functionality. That is, at low cost, a standard air-heat curtain can fulfill some of the functions of an air-conditioning installation and a heating system. It remains only to correctly install the unit and subsequently properly maintain it.
Choosing a place to install
Curtains are mounted only indoors. The specific location will depend on several parameters, the main of which is the zoning of the served site with its delimitation in temperature sections. As a rule, installation is carried out at the entrances and openings, where there is a collision of air flows with different microclimatic characteristics. At the same time, it is prohibited to install a thermal curtain in rooms where flammable substances are located, in vehicles, mines and in automated production facilities. If the room meets the requirements of the installation, you can proceed to the selection and determination of the optimal configuration for the installation of equipment.
Horizontal and vertical placement
Regardless of the installation point, third-party objects, structures and communications should not impede the direction of air flow. Also, the unit must not be affected by other climatic equipment, even if it is at a distance. However, cascading of several pieces of equipment is allowed. Installation can be done horizontally and vertically. As a rule, the installation of a thermal curtain on the front door is horizontal. This is a typical and most common arrangement of equipment, but it also provides for exposure of 15-20 cm directly from the boundaries of the opening.
For vertical installation, it should be noted that the direction of the air outlet should be as close as possible to the opening. In turn, the section of the exhaust nozzle is oriented to the level of the upper boundary of the door frame. In both installation configurations, about 25 cm of viewing space should remain, which will allow servicing the thermal curtain. A vertical installation in itself is advantageous in that it allows simplified access to the structure. Typically, such installation is carried out on the sides of the opening, allowing the location of two units, which provide balanced climate control.
Equipment installation
Most models focus on installation either to the right of the opening, or in the upper part - a horizontal way of placement. Installation is carried out using type-setting screws.
If a water thermal curtain is used, then first you should unscrew the hardware on which the front cover of the case is mounted. At this stage, you need to remove the water heat exchanger for further installation of the duct box.
Then a technical window opens for the integration of the nozzles. In some systems, for this, it is necessary to cut the factory jumpers. The case is mounted on the prepared place, and then the heat exchanger is re-installed in the corresponding niche. A typical installation of an electric thermal curtain does not require preliminary disassembly for the preparation of communications. Such systems can be mounted directly to the destination using self-tapping screws, brackets, mounting brackets and profiles - the specific type of fastener depends on the design parameters of the equipment. In any case, the kit will contain the necessary hardware for mounting.
Equipment connection
The input of the system into the communication infrastructure is carried out through pipes or electrical communications - it depends on whether the water or electric principle of operation is provided. In the case of a water system, plumbing fixtures are connected through fittings, adapters, hoses and regulated by a shut-off valve.
In some models, using auxiliary devices, you can expand the functionality of the thermal curtain. The water structure, for example, may include a mixing unit. If it is absent, then a water filter is mandatory. Electrical systems are connected to the network using circuit breakers. This device must completely relieve voltage from the device. The organization of installation wiring is carried out using a three-core cable with a cross section of 1 sq. Mm. The conductor must be made of copper. Additionally, fuses and other means of electrical protection are introduced into the system, which should be selected based on the features of the local power supply.
System management
Typically, curtains are equipped with panels with hardware or touch controls and remote controls, through which you can also adjust the operating mode of the equipment. Typically, devices have several modes of operation, providing for different bandwidth. The main controlled organ of the system is a fan - through a panel or remote control, for example, you can set the optimal speed of its rotation.
If the installation of a thermal curtain on an aqueous coolant is carried out, then the regulation possibilities should be calculated in advance, since they are provided by structural elements. In particular, the use of the remote control will be possible only with the optional inclusion in the infrastructure of the mixing unit, valve and thermostat.
Maintenance
During operation, ventilation systems are subject to contamination. Therefore, periodically it is necessary to disassemble the structure within the limits allowed by the instructions and clean the internal and external surfaces. Particular attention is given to water models. Such curtains are sensitive to mechanical stress on the coolant circulation circuits, because of which there is a risk of leakage. Checking the integrity of water communications is the main task of maintaining such systems. Also, the air-thermal curtain has its own characteristics of content. In the operation of such systems, attention should be paid to electrical safety, eliminating the risks of overloads and short circuits in the wiring.
Trouble-shooting
Often there are problems with fan installations. If this functionality does not work, then you should check the wiring, the presence of voltage in the network, the fan motor and the correct operation of the control devices. By the way, in order to protect the system from such situations, it is important to install a thermal curtain with reliable insulation of the power cable.
Standard insulation may not be enough, so it will not be superfluous to immerse the wire in a protective corrugated pipe. And also if there is a leak in the water system, then the plumbing infrastructure is checked with the subsequent restoration of its tightness. Most of the problems arise precisely because of violations in the communication channels.
Safety precautions
During operation of the curtain, the following safety rules must be adhered to:
- It is impossible to liquidate a coolant leak on its own if at the moment the main is working under pressure.
- Do not carry out repairs until the electrical infrastructure is de-energized.
- Regardless of the principle of operation of the equipment, the installation of a thermal curtain should be carried out with disconnected communications.
- In conditions of lowered negative temperature, the coolant should be completely drained.
Conclusion
The quality of the curtain will depend not only on compliance with the rules of installation work, but also on how correctly the choice of a particular model was made. When buying a device, the temperature limits, the number of people passing through the opening, the area of the room, etc. are taken into account.
As for manufacturers, the preference should be given to Ballu and Dantex models - these are specialized manufacturers of climate systems. In the domestic segment, the KEV thermal curtain from the Teplomash enterprise deserves attention. Reviews about it note high performance, flexibility of settings and affordable cost. By the way, the average modification characteristics of KEV-6P3231E is estimated at 18 thousand rubles. Models from more famous brands like Ballu can cost 20-30 thousand.
