Abstract
A washing/drying machine has objects to shorten a time required for a washing operation, to improve a heat exchange capability in a radiator and an evaporator, and to shorten a drying time for things to be dried, and comprises: an accommodating chamber in which things to be washed (things to be dried) are accommodated and in which a drying operation of the things to be washed is performed; a refrigerant circuit in which a compressor, a gas cooler, a decompression device, an evaporator and the like are successively connected to one another in an annular form via a piping and in which carbon dioxide is used as a refrigerant and which has a supercritical pressure on a high pressure side thereof; and blower means for blowing air which has exchanged heat with the radiator into the accommodating chamber to allow the air passed through the accommodating chamber to exchange the heat with the evaporator, wherein the blower means constitutes a circulation direction of the air passed through the gas cooler, and that of the refrigerant flowing in the gas cooler in such a manner as to form a counter-flow, and constitutes a circulation direction of the air passed through the evaporator, and that…
