PROBLEM TO BE SOLVED: To provide a dryer capable of effectively eliminating the heat filling in the dryer while reducing the time for dried object to be dried. SOLUTION: The dryer comprises a refrigerant circuit 10 in which a compressor 11, a radiator 12, an expansion valve 14 as a pressure reducer and an evaporator 15, etc. are connected to the piping one after another annularly, an air circulation path 20 for the air circulation from the radiator 12 to the evaporator 15 via a storage chamber 7 to return to the radiator 12 again by a fan 16 as a blowing means, and a heat exchanging means for the heat exchange between a heating medium in the outside and the refrigerant inside the refrigerant circuit 10 from the exit of the refrigerant of the evaporator 15 to the outlet of the refrigerant of the compressor 11. The heat exchanging means is composed of an external heat exchanger 50 for the heat exchange between the heating medium in the outside and the refrigerant in the intermediate pressure part of the compressor 11.
