<P>PROBLEM TO BE SOLVED: To obtain high operation efficiency in a heating/cooling simultaneous operation type air conditioner. <P>SOLUTION: This air conditioner 1 is a heating/cooling simultaneous operation type air conditioner having a compressing mechanism 2, a heat source-side heat exchanger 4, and use-side heat exchangers 6a, 6b, 6c, the compressing mechanism 2 is constituted to successively compress a refrigerant discharged from a former stage-side compressing element 2a by a latter stage-side compressing element 2b, and the heat source-side heat exchanger 4 has a main heat source-side heat exchanger 4a functioning as a radiator for the refrigerant in a radiating operation state requiring a function as the radiator for the refrigerant, and functioning as an evaporator for the refrigerant in an evaporating operation state requiring a function as the evaporator for the refrigerant, and a sub-heat source-side heat exchanger 4b functioning as an intermediate cooler for cooling the refrigerant after discharged from the former stage-side compressing element 2a before sucked by the latter stage-side compressing element 2b in the radiating operation state, and functioning as the evaporator for the refrigerant in the evaporating operation state. <P>COPYRIGHT: (C)2010,JPO&INPIT |
