PROBLEM TO BE SOLVED: To suppress lack of heating capacity of air of an object for heat exchange in a heat exchanger of a user side, in a refrigerant cycle device for heating air of the object for heat exchange by the heat exchanger of the user side.SOLUTION: When a temperature of feed air blown into a space for air conditioning cannot be increased up to a target temperature TAO in an indoor condenser 12 of a heat pump cycle 10 included in a gas injection cycle, a feed air volume flowing into the indoor condenser 12 is decreased. Thus, a temperature of a refrigerant condensed by the indoor condenser 12 is increased, while an amount of a compression work in a high-pressure side compression stage of a compressor 11 is increased, which suppresses lack of heating capacity of the feed air blown into the space for air conditioning. |
