Abstract
When a temperature of feed air blown into a space for air conditioning cannot be increased up to the target temperature in an indoor condenser of a heat pump cycle included in a gas injection cycle, the volume of the feed air flowing into the indoor condenser is decreased. Thus, the temperature of the refrigerant condensed by the indoor condenser is increased, while the amount of a compression work in a high-pressure side compression stage of the compressor is increased, which suppresses the lack of the heating capacity of the feed air blown into the space for air conditioning.
