Abstract (en)

[origin: EP2264380A1] An air-conditioning apparatus (1) comprises a two-stage compression-type compression mechanism (2), a heat source-side heat exchanger (4), a usage-side heat exchanger (6), a switching mechanism (3), and an intermediate heat exchanger (7). The switching mechanism (3) is a mechanism for switching between a cooling operation state wherein refrigerant is circulated sequentially through the compression mechanism (2), the heat source-side heat exchanger (4), and the usage-side heat exchanger (6); and a heating operation state wherein refrigerant is circulated sequentially through the compression mechanism (2), the usage-side heat exchanger (6), and the heat source-side heat exchanger (4). The intermediate heat exchanger (7) is a heat exchanger capable of functioning as a cooler of refrigerant discharged from a first-stage compression element (2c) and drawn into a second-stage compression element (2d) when the switching mechanism (3) has been set to a cooling operation state, and also capable of functioning as an evaporator of refrigerant whose heat is radiated in the usage-side heat exchanger (6) when the switching mechanism (3) has been set to a heating operation state.
