The above documents still have deficiencies. When in use, the fan draws air to create negative pressure, thereby causing air to enter from the air inlet, and the evaporator uses the air generated by evaporation to generate a dehumidification wheel. The cooling capacity is used to dehumidify the regenerated hot air and remove the moisture in the regenerated air. The condenser is arranged at the air inlet of the dehumidification wheel, and uses the condensation heat to heat the regenerated incoming air to regenerate the air.
