The refrigerant vapor is compressed only once by the compressor in each refrigeration cycle, referred to as single stage vapor compression. In the refrigeration cycle, the refrigerant mainly undergoes four processes: compression process, condensation process, throttling process and evaporation process. In the compression process, low-temperature and low-pressure refrigerant vapor is compressed into high-temperature and high-pressure refrigerant vapor; in the condensation process, the refrigerant vapor with high temperature and high pressure is condensed into refrigerant liquid with high temperature and high pressure; in the throttling process, the refrigerant liquid with high temperature and high pressure is throttled and depressurized into refrigerant liquid with low temperature and low pressure; in the evaporation process, the low-temperature and low-pressure refrigerant liquid is evaporated into low-temperature and low-pressure refrigerant vapor, and thus a refrigeration cycle is completed.
