<P>PROBLEM TO BE SOLVED: To solve the problem that a compressor cannot be controlled by a more optimum lead angle under a load condition of the compressor since the lead angle is decided irrespective of load fluctuation of the compressor as the lead angle decided at every revolution of the compressor is stored in a compressor lead angle deciding means and the compressor is controlled in a compressor controller. <P>SOLUTION: The lead angle is decided based on a compressor current detected by a compressor current detecting means 3 and a revolution detected by a compressor revolution detecting means 5. Thus, the compressor can be controlled with the optimum lead angle. <P>COPYRIGHT: (C)2010,JPO&INPIT |
