Systematic Troubleshooting an Oil-Logged Evaporator

摘要

Refrigerant migration deals with refrigerant migrating back to the compressor's crankcase during the off cycle. This migration of refrigerant is due to a pressure difference between the compressor's crank-case and the refrigerant. Refrigerant migration can cause the compressor's crankcase to lose its oil, thus circulating the oil throughout the refrigeration system. This oil in circulation usually gets caught in the evaporator and can cause an oil-logged evaporator.
