Causes of compressor oil deterioration
1. Mixing of oil and water Moisture is mixed in the refrigerator oil. If due to improper operation of the water into the refrigeration system, and the mixing of freezer oil, will reduce the viscosity of the freezer oil, reducing the lubricating properties of the oil. 2, high temperature oxidation...Read more -
Common problems and solutions of liquid r...
Liquid refrigerant migration Refrigerant migration refers to the accumulation of liquid refrigerant in the compressor crankcase when the compressor is shut down. As long as the temperature inside the compressor is lower than the temperature inside the evaporator, the pressure difference between t...Read more -
