An evaporator 21, a condenser 22 and a surface cooler 23 for heat exchange are arranged in the heat exchange chamber 2, and when the evaporator 21 works, the air passing through the surface of the evaporator 21 is cooled and dehumidified; when the condenser 22 is in operation, the temperature of the air passing over the surface of the condenser 22 increases; when the surface cooler 23 is filled with hot water, the temperature of the air passing through the surface of the surface cooler 23 rises, and when the surface cooler 23 is filled with cold water, the temperature of the air passing through the surface of the surface cooler 23 drops. The evaporator 21 is operated only when the temperature-increasing dehumidification mode is operated, and the condenser 22 is operated only when the temperature-increasing dehumidification mode is operated.

In this embodiment, the evaporator 21 is disposed in the heat exchange chamber 2 near the air return chamber 1, which means that when air is conveyed from the air return chamber 1 into the heat exchange chamber 2, it is necessary to pass through the evaporator 21, then the condenser 22 and the surface air cooler 23.
