Abstract
To provide a refrigerating cycle apparatus capable of improving cooling ability by water spray to perform an efficient operation while suppressing decrease in collected power by an expander. The refrigerating cycle apparatus includes: a first compressor that compresses the refrigerant; an expander that decompresses and expands the refrigerant to collect power for expansion; a second compressor that is driven by the power collected by the expander to further compresses the refrigerant compressed by the first compressor to transmit it to a main radiator; a heat exchanger having an intercooler that cools the refrigerant compressed by the first compressor and a main radiator that cools the refrigerant compressed by the second heat exchanger to transmit it to the expander; indoor heat exchangers that heat the refrigerant decompressed by the expander; and a water spray apparatus that sprays water onto the outer surface of the intercooler and the main radiator. The water spray apparatus sprays water such that the water spray amount per heat transfer area of the intercooler becomes larger than that of the main radiator.
