As shown in fig. 7, when the outlet air temperature of the evaporator 40 is higher than the temperature setting range, the opening of the throttle valve is decreased, the pressure drop is increased, the pressure of the evaporator 40 is decreased, the temperature of the refrigerant in the evaporator 40 is decreased, and under the condition that the temperature of the air before entering the evaporator 40 is not changed, the temperature difference between the air temperature at the inlet of the evaporator 40 and the temperature of the refrigerant in the evaporator 40 is increased, so that the heat exchange amount of the evaporator 40 is increased, the rate of the air passing through the evaporator 40 to separate out the condensed water is increased, and meanwhile, the heat exchange amount of the condenser 20 is increased (the heat exchange amount of the condenser 20 is influenced by the power consumption of the compressor 10 and the flow rate of the refrigerant), so that the heat of the air entering the clothes drying chamber 60 is increased, and the moisture absorption capacity of;
when the outlet air temperature of the evaporator 40 is lower than the temperature setting range, the opening of the throttle valve is increased, the pressure drop is reduced, the pressure of the evaporator 40 is increased, the temperature of the refrigerant in the evaporator 40 is increased, and the heat exchange amount of the evaporator 40 is reduced, so that the outlet temperature of the evaporator 40 is increased.
When the outlet air temperature of the evaporator 40 is within the temperature setting range, the opening degree of the throttle valve will be kept unchanged.
Therefore, the adjustment of the temperature of the inlet air and the moisture absorption efficiency of the inlet air in the clothes drying cavity 60 is realized by controlling the throttle valve through the throttle valve control unit 150.
