Refrigeration system failure symptoms

Symptoms of refrigeration system failure 　 　 　 　 1. Detection of pressure and temperature of refrigeration system　　 (1) The pressure concept of the refrigeration system The refrigeration system can be divided into high and low pressure during operation. The high pressure section is from the discharge port of the compressor to before the throttle valve. This section is called the evaporation pressure.

What is the difference between an air compressor and a refrigeration compressor

The air compressor is the same as the refrigeration compressor in that it is the same compressor, the difference is that its working principle and working medium are different. An air compressor compresses gas, and a refrigeration compressor is a device t器2䀀

The common oil shortage failures of scroll refrigeration compressors are here

The compressor has been short of oil for a long time-the mechanism and the friction pairs are overheated, resulting in bearing sintering and shaft holding. The compressor is short of oil for a short time-the mechanism and the friction pairs are abnorma器2䀀
