Heat pump that saves electricity bills
The refrigerant gas is then compressed into a high-temperature and high-pressure vapor in the compressor, and the high-temperature and high-pressure gas is cooled and condensed into a high-pressure liquid by a low-temperature heat source (such as cooling water) in the condenser. Then it is throttled into low temperature and low pressure liquid refrigerant through throttling elements (capillary tube, thermal expansion valve, electronic expansion valve, etc.)
