Working principle of air conditioner compressor

- Apr 22, 2020-

1. The air conditioning compressor plays the role of compressing and driving the refrigerant in the air-conditioning refrigerant circuit. The working circuit is divided into an evaporation area and a condensation area, and the indoor unit and outdoor unit belong to the high-pressure or low-pressure area, respectively. The compressor is generally installed outdoors. The compressor draws the refrigerant from the low-pressure area and sends it to the high-pressure area to cool and condense through the compressor. The heat energy is emitted into the air through the fins. The refrigerant also changes from gaseous to liquid, and the pressure rises. high. The refrigerant then flows from the high-pressure area to the low-pressure area, and is ejected into the evaporator through the capillary. The pressure drops suddenly, and the liquid refrigerant immediately becomes gaseous, absorbing a large amount of heat in the air through the heat sink. In this way, the machine continues to work, it will continue to absorb the heat energy at one end of the low-pressure zone into the refrigerant, and then send it to the high-pressure zone to distribute it to the air, which plays a role in regulating the temperature.

2. During the cooling operation of the air conditioner, the low-temperature and low-pressure refrigerant gas is sucked by the compressor and pressurized to become a high-temperature and high-pressure refrigerant gas. The high-temperature and high-pressure refrigerant gas radiates heat in the outdoor heat exchange gas and becomes medium-temperature and high-pressure Liquid, medium-temperature and high-pressure liquid passes through throttling parts to reduce pressure and become low-temperature and low-pressure liquid. The low-temperature and low-pressure liquid refrigerant absorbs heat and evaporates in the indoor heat exchange gas and becomes low-temperature and low-pressure gas, and then enters the compressor Compression, reciprocating cycle.

3. The compressor is the heart of the refrigeration system. No matter it is in air conditioning, cold storage, chemical refrigeration process, etc., it is necessary to ensure the important link of the compressor! There are many types and forms of refrigeration compressors, which can be divided into volume according to the principle There are two types of type and speed type, of which the volume type is the most common.
