<P>PROBLEM TO BE SOLVED: To provide a refrigerating cycle device capable of improving reliability without increasing costs. <P>SOLUTION: The device includes an outdoor fan motor 62 driving a blower fan of an outdoor heat exchanger 3, an indoor fan motor 72 driving a blower fan of an indoor heat exchanger 5, an outdoor fan driving unit 8 driving the outdoor fan motor 62, an indoor fan driving unit 9 driving the indoor fan motor 72, and a control unit 10 controlling a four-way valve 2, an expansion mechanism 4, the outdoor fan driving unit 8, and the indoor fan driving unit 9. When receiving a predetermined command for generating heat from the outdoor fan motor 62 in defrost operation when the outdoor heat exchanger 3 functions as an evaporator, the outdoor fan driving unit 8 applies a voltage for generating heat from the outdoor fan motor 62 to the outdoor fan motor 62 while stopping the outdoor fan motor 62. <P>COPYRIGHT: (C)2013,JPO&INPIT |
