What are the reasons for the excessive consumption of lubricating oil in the chiller?

1. Malfunction of oil separator

The refrigerating lubricating oil consumption of the refrigerator is too large, usually due to the problem of the oil separator. The failure of the oil separator is more common. Since the oil separator cannot complete the separation of the refrigerated lubricating oil and the refrigerant, the refrigerated lubricating oil flows with the refrigerant , It will not only cause the compressor to lack of refrigerated lubricant, but also make the subsequent refrigeration process become abnormal.

2. Compressor suction and discharge pressure and temperature problems

Since the oil separators of most refrigerators are separate oil separators, they are separated by using the different densities and gravity of the refrigerant and the refrigerating lubricating oil. If the compressor suction and discharge pressure and temperature have problems, it will cause The separation effect of refrigerant and refrigerating lubricating oil is not good.
