The specific control method, model and specification are not described in detail here. In order to suppress frost on the surface of the evaporator 11, the air entering the main body 10 for heat exchange with the evaporator 11 can be dried. Frosting is suppressed by reducing the moisture content in the air in contact with the evaporator 11. The type of desiccant with strong adsorption and regeneration capabilities in a low temperature environment, the regeneration of the desiccant and the regeneration method have been disclosed in detail in the prior art. For example, the publication number: CN evaporator 11 driving screw 3188271B has detailed records, which are not described here.
