To prevent a refrigeration oil from drying up due to generation of foaming, by preventing a compressor from sucking a low-temperature refrigerant at the start-up of a heating operation.SOLUTION: An air conditioner includes: a compressor 101 driven by an electric motor; power generation means 102 for providing power to the compressor; a waste heat recovery heat exchanger 105 for performing heat exchange between the waste heat of the power generation means 102 and the refrigerant; and a power means control device 106 for using power from the power generation means 102 and power from a commercial power supply as a driving source of the compressor 101 by using one of them or by combining them by an air conditioning load. The power means control device 106 selects one of a rated operation and stop for the power generation means 102, and at the start of a heating operation, the power generation means 102 is started before driving the compressor 101, and after the waste heat temperature of the power generation means 102 has reached a predetermined temperature, the compressor 101 is driven.SELECTED DRAWING: Figure 1
