Abstract:
1. A heat exchange apparatus including an outdoor unit having a compressor ( 2 ), an outdoor heat exchanger ( 3 a , 3 b ) serving as a heat-source side heat exchanger and an outdoor expansion valve ( 27 a , 27 b ) and at least one indoor unit ( 5 a , 5 b ) having an indoor expansion valve ( 18 a , 18 b ) and an indoor heat exchanger ( 6 a , 6 b ) serving as a use-side heat exchanger, the outdoor heat exchanger and the indoor heat exchanger being connected to each other through an inter-unit pipe to constitute an heat exchange cycle, characterized in that a heat exchanger ( 28 a , 28 b , 65 , 85 , 101 , 111 ) for carrying out heat exchange between a heat medium and refrigerant after the refrigerant is heat-exchanged in the heat-source side heat exchanger ( 3 a , 3 b ) or carrying out heat exchange between the heat medium and the refrigerant with no heat-exchange of the refrigerant in the heat-source side heat exchanger ( 3 a , 3 b ) during operation is provided between the outdoor expansion valve ( 27 a , 27 b ) and the heat-source side heat exchanger ( 3 a , 3 b ).
