The working principle of commercial central air conditioner

Commercial central air conditioners are different from household air conditioners. They are more specialized and special air conditioners. The installation and design requirements for air conditioners are much higher than ordinary air conditioners. One of the main ways for manufacturers to obtain orders is through bidding meetings. For large projects, To win the bid, the installation design plan must participate in the front-end design of the project, which requires the company to provide users with personalized services. Large-scale central air-conditioning is a relatively large facility for housing construction. If the installation design is not personalized, the central air-conditioning cannot be fully reflected. The advantages of the air conditioner may even bury hidden quality problems for the normal use of air conditioners. The personalized service of commercial central air-conditioning has become a watershed in the large-scale central air-conditioning industry.

The working process of commercial central air-conditioning-the principle of refrigeration:

The air conditioning system has a built-in heat-absorbing medium—refrigerant, commonly known as refrigerant. The refrigerant passes through the expansion valve and evaporates and gasifies inside the indoor unit. The indoor unit fan blows the cold wind into the room, absorbing the heat energy in the indoor air, and the refrigerant passes through the pipe. Back to the suction side of the compressor, the temperature of the refrigerant is increased through the compression of the compressor. The outdoor unit converts the refrigerant from the vaporized state to the liquefied state. During the conversion process, a large amount of heat is released. The heat is discharged, through the repeated cycle, and finally achieves the purpose of refrigeration.

The working process of commercial central air-conditioning-heating principle:

The air-conditioning system directly injects the high-temperature and high-pressure liquid compressed by the compressor into the condenser of the indoor unit through the conversion of the electric four-way valve, and releases a large amount of heat to be discharged into the room by the fan to absorb the cold air in the room; the system refrigerant passes through the expansion valve section After flowing through the outdoor unit evaporator, it is converted from liquid to gas. The cold air absorbed in the indoor unit is discharged to the outside through the outdoor unit evaporator and fan, and the refrigerant returns to the suction side of the compressor through the pipeline. Through repeated cycles, the purpose of heating is achieved. c
