The central air conditioning system has a lot of advantages, one of which is the complete absence of noise from the working installation, because the air conditioner itself is located outdoors, and cool air is supplied to them through the air ducts. There are several varieties of systems that use different installations. One of them is the central frame air conditioning panel type.
Design Features
The stitched structure is assembled on a metal frame (frame) by combining several modules, each of which carries its own functions. It is possible to equip equipment according to customer requirements by installing one or another modular unit. In this case, the installation can be assembled in one or two tiers.
Air conditioners central frame-panel - a structure whose sections consist of a frame (aluminum profile) and sandwich panels, which are easily dismantled and assembled into a single structure.
Benefits:
- ease of transportation and loading and unloading even in cramped conditions,
- simple assembly and disassembly
- easy maintenance and repair.
Execution KTsKP
Manufacturers offer several options for the execution of frame-panel air conditioners:
- standard internal design, designated by the abbreviation KTsKP, which is installed in ventilation chambers or in special rooms for air conditioners;
- outdoor performance with the addition of the letter "H" (KTsKP-N), which are mounted on the street, most often on the roofs of buildings;
- KTsKP-S - northern version for use in regions with low temperatures;
- KTsKP-V - explosion-proof option;
- KTsKP-Ae - earthquake-resistant equipment used in air conditioning systems of nuclear power plants;
- KTsKP-Gn - used in rooms with increased requirements for hygiene standards;
- KTsKP-P - are made for installation in the subway and other underground structures.
All proposed air-conditioning frame-panel installations are a large lineup in terms of equipment performance. The range of technical characteristics is quite impressive - 400-100000 m³ / h, therefore, it will not be difficult to coordinate and select the necessary air conditioning for the required parameters of the premises or buildings.
Keep in mind: the greater the performance, the larger the size of the modules. The smallest compact module of the KTsKP-1.6 brand has a block section of 592x287 mm. The most powerful KTSKP-100 has a section size of 3660x2440 mm.
Composition of air conditioners
Depending on how the air-conditioning unit will work - for cooling or additionally for heating the supplied air, two configuration options are considered:
- without installing a heating module;
- with heating module.
The heating section is represented by three models: water, steam or electric. In the first two cases, a heat exchanger is installed in the module, through the tubes of which hot water or steam moves. In the latter case, these are ordinary electric heating elements.
General equipment in sections:
- Entrance. Flaps are installed in the design, with the help of which the volume of air supply is regulated.
- Filtration, trapping dust, insects and other particles that fly into the air duct with the air. Usually two types of filters are installed: coarse cleaning (clean up to 60%) and fine cleaning (delay up to 90% dirt). All filters are made to fit the module in the form of frames.They are inserted and removed from the section without disassembling the air conditioner.
- Cooling section. Two different heat exchangers are used, depending on the type of refrigerant used in the system. If it is cold water, a steel tubular heat exchanger is installed. If freon or other refrigerant of this type, a tubular copper heat exchanger is used, to which a special collector is added. All types of heat exchangers are equipped with aluminum fins (plates), which increase the heat transfer area. All cooling sections of the air conditioners of the central frame-panel are equipped with condensate collectors and drip collectors.
- Fan A fan has been installed, the main functions of which are to take air from the street and supply it to the refrigerated rooms. The module can be installed between any sections or directly at the outlet when connecting the air conditioner to the internal air ducts.
- Sound absorption section. The purpose is to reduce the sounds emanating from the fan. Inserts are inserted inside, which are made of several layers of folded mineral wool or fiberglass. The latter is selected taking into account the density.
The air heating section can be installed before or after the cooling module.
Recent research in the field of energy saving has made it possible to use additional recovery sections in the air conditioners of the central heating and cooling plant. They pre-heat the air, which is then heated to the required temperature. In this case, heating occurs due to the temperature of the air flow output from the ventilation. There are three types of equipment used: plate, rotary and recuperators with an intermediate heat exchanger.
Another block that is used in the design of air conditioners of the KTsKP brand is the module for humidification or drainage of air masses. With it, you can control the humidity in the rooms. Control can be carried out in each room separately or in all at once.
terms of Use
Frame-panel equipment is equipped with automation, which is responsible for the correct operation of all modules. With its help, the set parameters for the operation of the air conditioning system are monitored, as well as protection against emergency situations.
Automation is based on temperature sensors that monitor indoor temperature. It is they who give signals to fans that turn off or reduce the speed of rotation of the impeller. In this way, the temperature regime is regulated, or the coolant / refrigerant supply valves are closed.
All automation is combined by a central unit that reads information from controllers (sensors).
There are no serious requirements for operating conditions. It is necessary to clean or change the filters in time, check the heat exchangers for free space between the ribs, as they are sometimes clogged with dust. It is necessary to check the operation of fans, air conditioning compressor and other devices.
Prices for equipment depend on the performance of units and performance. KTsKP-3.15 without automation can be bought for 140,000 rubles. Complete with automation system price - 220,000 rubles. The same performance air conditioner version "C" costs 350,000 rubles.
