Condensation and dehumidification principle: the evaporator 5 is used as cooling equipment to cool the wet air to the dew point temperature or below, separate out water vapor with the moisture content larger than the saturated moisture content, reduce the absolute moisture content of the wet air, and then utilize the condensation heat of the refrigerant to heat the low-temperature wet air, thereby further reducing the relative humidity of the air and achieving the purpose of high-efficiency dehumidification.
The working principle of the rotary wheel dehumidification system is as follows: the dehumidifying rotor 21 is divided into a rotor dehumidifying area 22 and a rotor regenerating area 23, the wet air enters the dehumidifying area through the processing fan 11, and the moisture in the wet air is absorbed by the moisture absorbent on the dehumidifying rotor 21, so as to achieve the purpose of deep dehumidification.
