As the inverter device and the DC converter are mounted on a bottom face of the compressor or a part hardly heated by the winding in order to utilize the heat generation of the inverter device and the DC converter in preheating, the compressor can be effectively heated. Further as DC current is used, the noise is not generated at all in preheating operation. Furthermore, as the output of the DC converter can be adjusted to achieve the optimum heating state in accordance with the necessity, the power can be saved. Thus, the air conditioner capable of conducting sufficient preheating operation with low noise while saving power, can be provided.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
