<P>PROBLEM TO BE SOLVED: To provide a refrigerating cycle device preventing decline in frost performance. <P>SOLUTION: The refrigerating cycle device includes a refrigerating cycle constituted by sequentially interconnecting a compressor 1, a condenser 2, an expansion mechanism 3 and an evaporator 4 by refrigerating piping annularly. The refrigerating cycle device further includes a carrying means 5 for circulating a refrigerant in the refrigerating cycle without compressing the refrigerant by the compressor 1 during defrosting of the evaporator 4. Thus, since compression is not performed by the compressor 1, thermal energy can be easily received and thermal transfer of the received heat to the evaporator 4 can be performed without change, to easily achieve temperature necessary for defrosting. <P>COPYRIGHT: (C)2010,JPO&INPIT |
