Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an air conditioner in which an operation of a refrigerant pump can be made in a requisite minimum state and it shows a superior energy saving state. SOLUTION: A compressor 34 driven by an engine 33, an indoor heat exchanger 18, an outdoor heat exchanger 31 and a four-way valve 32 are connected through a refrigerant pipe passage 14. A branch pipe passage 42 having its one end communicated with a high pressure liquid pipe 40 of the refrigerant pipe passage 14 at the time of heating operation and further having the other end communicated with a high pressure gas pipe 39 at the time of heating operation in the refrigerant pipe passage 14 is provided with a refrigerant pump 44, a branch pipe passage opening and closing valve 45 and an engine discharged heat recovering heat exchanger 46. There is provided a bypass pipe passage 59 for bypass connecting between an upstream side of either the high pressure liquid pipe 40 or the branch pipe passage 42 higher than the refrigerant pump 44 at the time of heating operation and the engine waste heat recovering heat exchanger 46 and further the bypass pipe passage 59 is provided with a bypass pipe passage opening and closing valve 62.
