Abstract:
　During the execution of a heating operation in which a use-side heat exchanger is made to function as a condenser when there is low external air temperature of a pre-established level, a low external air temperature heating operation activation mode is executed in which, while refrigerant which has been discharged from a compressor is made to flow into the use-side heat exchanger, refrigerant is supplied, via an injection pipe, to an injection port in the compressor, and a part of refrigerant that has radiated heat in a heat-source-side heat exchanger is supplied to the compressor, and subsequently a transition is made to a low external air temperature heating operation mode in which, while refrigerant which has been discharged from the compressor is made to flow into the use-side heat exchanger, the refrigerant is supplied to the injection port in the compressor, via the injection pipe.
