For example, the dehumidifier in the present application performs a dehumidifying process of the dehumidifier by using a compressor, a condenser, and an evaporator. The dehumidification process involves compression, condensation and evaporation, and supplies refrigerant to the air that has been conditioned and heat exchanged.

The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

The evaporator evaporates the liquid-phase refrigerant and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant.

Wherein, the fan sucks air into the dehumidifier, the air passes through the evaporator, and water vapor in the air is condensed into liquid water; and after the air is radiated by the condenser, the air is discharged out of the dehumidifier from the air outlet.
