PURPOSE:To eliminate the need for the DC power supply of the second inverter, and to miniaturize the device by supplying DC power to the second inverter driving a motor for a fan having small capacity from an auxiliary DC power supply in the first drive circuit containing the first inverter driving a motor for a compressor. CONSTITUTION:In the air conditioner such as a separate type room air conditioner, an indoor unit 27 is arranged into a room 29 air-conditioned, and formed by a fan device 31 consisting of the indoor fan and the driving motor and an indoor heat exchanger 32. On the other hand, an outdoor unit 28 is formed by the compressor section 3, the first drive circuit 2-1 driving the motor for the compressor, an outdoor fan 33, an outdoor motor 34, the second drive circuit 2-2 driving the motor for the fan, an outdoor heat exchanger 35 and a capillary tube 36. The first drive circuit and the second drive circuit are connected by a low voltage DC line 38. |
