い。As described above, in the embodiment of the present invention shown in FIG. 2 and FIG. To drive an outdoor fan motor with two inverters, one current is required6. The configuration is such that only ij supplies DC power to two inverters. From this point of view, the configuration of the DC power supply is simpler than the case where the DC power supply is provided separately. Even in this case, the effects of the present invention will be even greater if one DC power supply supplies DC power to the compressor motor, the outdoor fan motor, and the inverter of the indoor fan motor Sowazo Jl.

装置の小形化を図れる。As described above in the embodiment, when the compressor motor and the fan motor used for cooling the heat exchanger are driven by the inverter, the DC power supplied to the inverter for driving the compressor motor is 1. Since the DC power supply is also applied to the drive input of the fan motor, there is no need to provide a DC power supply specifically for the fan motor. The configuration is simplified 1, and the device can be miniaturized as an air conditioner that saves energy by operating the electric motor at variable speed.
