The dehumidifier 100 performs a refrigeration cycle through the compressor 51, the condenser 522, the throttle device 54, and the evaporator 521. The refrigeration cycle includes a compression process, a condensation process, an expansion process, and an evaporation process.

The working principle of the dehumidifier 100 is as follows: when the dehumidifier 100 is in dehumidification operation, high-temperature and high-pressure refrigerant gas discharged from the compressor 51 enters the condenser 522, the refrigerant is condensed in the condenser 522, the airflow flowing through the condenser 522 takes away heat released by the refrigerant of the condenser 522, the refrigerant is changed into medium-temperature and high-pressure liquid from the high-temperature and high-pressure gas in the condenser 522, the medium-temperature and high-pressure refrigerant liquid passes through the throttling device 54, the refrigerant is throttled and depressurized by the throttling device 54 to be changed into low-temperature and low-pressure gas-liquid mixed refrigerant, and then enters the evaporator 521, and the refrigerant is evaporated in the evaporator 521.

The air outside the dehumidifier 100 enters the periphery of the evaporator 521 inside the dehumidifier 100, the refrigerant absorbs the heat of the air flow flowing through the periphery of the evaporator 521 in the evaporation process of the evaporator 521, so that the temperature of the air flow flowing through the evaporator 521 is reduced, the dew point temperature of the air flow flowing through the surface of the evaporator 521 is also reduced, the water vapor inside the air flow is condensed into dew to be separated out of the air flow, the effect of reducing the relative humidity of the air flow flowing through the surface of the evaporator 521 is achieved, and the dehumidification effect is achieved. The refrigerant that has been evaporated in the evaporator 521 to become a low-temperature and low-pressure gas enters the compressor again, and the compressor 51 compresses the low-temperature and low-pressure gas refrigerant and discharges the compressed low-temperature and low-pressure gas refrigerant into the condenser 522, thereby performing a refrigeration cycle again.
