The subject of the invention is to dry the inner wall surface of a vehicle compartment by vaporizing moisture frosted or condensed on the inner wall surface of the vehicle compartment. To achieve the subject, the invention utilizes a heat-pump refrigeration device to alternately perform heating and cooling operations. After vaporizing the moisture frosted or condensed on the inner wall surface of the vehicle compartment, the condensed water is condensed in the heat exchanger inside the vehicle compartment and discharged out of the vehicle compartment. The refrigeration device of the invention includes a compressor for compressing refrigerant, an external heat exchanger for performing heat exchange with the air outside the vehicle compartment, an external air blower corresponding to the external heat exchanger, an internal heat exchanger for performing heat exchange with the air inside the vehicle compartment, an internal air blower corresponding to the internal heat exchanger, a first temperature detector for
