W221 AC Compressor

W221 AC Compressor

1.       Product Intro

The air-conditioning compressor plays the role of compressing and driving the refrigerant in the air-conditioning refrigerant circuit, which is an important component of the automotive air-conditioning cooling system.

2.       Four cycle processes of automobile air conditioning:

* Compression process: the AC Compressor sucks the low-temperature and low-pressure refrigerant gas at the outlet of the evaporator, compresses it into high-temperature and high-pressure gas and discharges it to the W221 AC Compressor;

* Heat dissipation process: high temperature and high pressure superheated refrigerant gas enters the condenser, due to the reduction of pressure and temperature, the refrigerant gas condenses into liquid and discharges a large amount of heat;

* Throttling process: After the refrigerant liquid with high temperature and pressure passes through the expansion device, the volume becomes larger, the force and temperature drop sharply, and the liquid is discharged from the expansion device in the form of mist (fine droplets);

* Endothermic process: The mist-like refrigerant liquid enters the evaporator, so the boiling point of the refrigerant is much lower than the temperature in the evaporator, so the refrigerant liquid evaporates into a gas.

During the evaporation process, a large amount of surrounding heat is absorbed, and then the low-temperature and low-pressure refrigerant evaporates into the W221 AC Compressor.

The above process is carried out over and over again to achieve the purpose of reducing the air temperature around the evaporator.
