When only refrigeration is needed, firstly, the condensation reheating electromagnetic valve 5 and the refrigeration electromagnetic valve 6 are closed, and the liquid refrigerant remained in the condenser 10 in the reheating chamber is pumped out from the path of the dehumidification evaporator 9 and is transferred to the outdoor condenser 4 by the compressor 2; and then the refrigeration electromagnetic valve 6 is opened for refrigeration. The refrigerant evacuation action is to reduce the refrigerant charge of the system and to stabilize the system operation, so as to be beneficial to no low-pressure alarm during the refrigeration operation.
