Title:
冷凍サイクル装置
Document Type and Number:
Japanese Patent JP4242131
Kind Code:
B2
Abstract:
It is an object of the present invention to reduce the constraint that the density ratio is constant as small as possible, and to obtain high power recovering effect in a wide operation range. A refrigeration cycle apparatus uses carbon dioxide as refrigerant and has a compressor (1), an outdoor heat exchanger (3), an expander (6), an indoor heat exchanger (8) and an auxiliary compressor (10). The auxiliary compressor (10) is driven by power recover by the expander (6). When refrigerant flows using the indoor heat exchanger (8) as an evaporator, a discharge side of the auxiliary compressor (10) becomes a suction side of the compressor (1), and when refrigerant flows using the indoor heat exchanger (8) as a gas cooler, a discharge side of the compressor (1) becomes a suction side of the auxiliary compressor (10).
