To understand the working principle of heat pump, first of all, we should understand the working principle of refrigeration system. Refrigeration system (compressed refrigeration) generally consists of four parts: compressor, condenser, throttle valve, evaporator. Its working process is: low temperature and low pressure liquid refrigerant (such as Freon), first in the evaporator (such as air conditioning indoor units) from high temperature heat source (such as ambient temperature air) heat absorption and gasification into low pressure vapor. The refrigerant gas is then compressed into high-temperature and high-pressure vapor in the compressor. The high-temperature and high-pressure gas is cooled and condensed into high-pressure liquid by a low-temperature heat source (such as cooling water) in the condenser. The liquid refrigerant at low temperature and low pressure is throttled by throttling elements (capillary, thermal expansion valve, electronic expansion valve, etc.). This completes a refrigeration cycle.
