<P>PROBLEM TO BE SOLVED: To provide a refrigerating cycle apparatus that improves heat dissipation performance by fully using sensible heat of water spread to an air-cooled condenser as a cooling heat source. <P>SOLUTION: A refrigerating cycle apparatus 100 includes a two-stage compressor 3, an air-cooled condenser 5 that dissipates heat from a coolant delivered from the two-stage compressor 3, an expansion valve 13 that reduces the pressure of the coolant discharged from the air-cooled condenser 5, an indoor cooler 14 that allows heat to be absorbed into the coolant discharged from the expansion valve 13, a water supply passage 22 through which water to be spread to the air-cooled condenser 5 is supplied, and a water-oil cooler 20 that performs heat exchange between water flowing through the water supply passage 22 and a refrigerating machine oil discharged together with the coolant from the two-stage compressor 3. <P>COPYRIGHT: (C)2013,JPO&INPIT |
