ABSTRACT:
A drying machine includes a first chamber, a second chamber, a first control device mounted in the first chamber and including a first main condenser, a first secondary condenser, a first main evaporator, and a first secondary evaporator, a second control device mounted in the second chamber and including a second main condenser, a second secondary condenser, a second main evaporator, and a second secondary evaporator, and a common compressor supplying a refrigerant to the first control device and to the second control device. In such a manner, when the first control device performs a cycle to increase the temperature in the first chamber, the second control device performs a cycle to decrease the temperature in the second chamber, and when the first control device performs a cycle to decrease the temperature in the first chamber, the second control device performs a cycle to increase the temperature in the second chamber.
