TH6019C3 - Refrigeration system prevents liquid refrigerant from flowing back into the compressor while defrosting - Google Patents

Abstract

DC60 Refrigerant refrigerant from flowing back into the compressor while defrosting can be done by connecting the refrigerant transfer hose from the Discharge tube before the three-way valve to the refrigerant suction line ( Suction) by connecting to the area inside the pipe Connect to each other To bring superheated vapor from the refrigerant pipeline (Discharge) to mix with the Liquid cooling that flows mixed in the pipe of the refrigerant suction (Suction) to become a saturated vapor. Before falling asleep into the compressor Helps to prevent liquid refrigerants that have not yet become saturated. It can flow back into the compressor while defrosting. Refrigeration system prevents liquid refrigerant from flowing back into the compressor while defrosting This can be done by connecting the refrigerant pipeline from the refrigerant pipeline. (Discharge) area before the three-way valve into the refrigerant suction pipe (Suction) by connecting through the area within the pipe to connect to each other. To bring the superheated vapor from the refrigerant pipeline (Discharge) to mix with the liquid refrigerant flowing mixed in the refrigerant suction pipe (Suction) to become a saturated vapor before falling asleep into the compressor. It prevents liquid refrigerant that is still not fully saturated from flowing back into the compressor while defrosting.
