Introduction to the working principle of central air-conditioning compressor

As people have higher and higher requirements for the quality of life, many people have begun to choose central air conditioners when choosing air conditioners. There will always be some problems when using the air conditioner, and sometimes we simply don't have time to solve it, so it is very important to master the working principle of the air conditioner compressor. Next, the Shanghai Central Air Conditioning Project will tell you the working principle of the air conditioning compressor, so that you can solve it as soon as possible when it has problems.

Before understanding the working principle of the air-conditioning compressor, let's first understand the working circuit of the air-conditioning compressor. The working circuit of the air-conditioning compressor is divided into an evaporation zone and a condensation zone, and the air-conditioning compressor plays a role of compressing and driving the refrigerant in the air-conditioning refrigerant circuit.

When air conditioning is refrigerating, the central air-conditioning compressor extracts the refrigerant from the low-pressure zone and then sends it to the high-pressure zone for cooling and condensation. The heat is distributed to the air through the radiating fins. The refrigerant also changes from gas to liquid, and the pressure increases. The refrigerant then flows from the high-pressure area to the low-pressure area, radiates into the evaporator through the capillary tube, and the pressure drops sharply. The liquid refrigerant immediately becomes a gaseous state, and absorbs a large amount of heat in the air through the heat sink. This cycle application completes the refrigeration system.

After the compressor is throttled by the throttling device, it is passed into the evaporator to cool and exchange the heat of the medium that needs to be cooled. For example, if the evaporator is connected to each room in the building, the serpentine tube in the evaporator will exchange heat with the air, and then the cold air will be blown into the air in the room through the blast. The refrigerant in the serpentine tube of the evaporator turns into low-pressure vapor and returns to the compressor after heat exchange, and then is compressed by the compressor, so that the refrigeration system is completed by recycling.

The air conditioner maintenance tells you that the heating system is roughly based on this principle, but in the opposite way. In general, the working principle of the air-conditioning compressor can be summarized as follows: When the central air-conditioning compressor is working, it continuously absorbs the heat at one end of the low-pressure zone.
