<P>PROBLEM TO BE SOLVED: To suppress an increase in power receiving capacity and the occurrence of higher harmonic waves by improving the balance of a load in view from a multi-phase power source. <P>SOLUTION: Line voltage of all phases, namely, R-, S- and T-phases of a three-phase power source is supplied to a compressor 103 via a compressor drive mechanism 102. R-phase voltage is supplied to a drive mechanism power source 104. S-phase voltage is supplied to a fan motor. T-phase voltage is supplied to an air-conditioner indoor unit 200. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
