Abstract
In an operation control apparatus of a compressor, a current, a voltage an d a TDC, etc. applied to a compressor are detected, a speed and a TDC are constantly controlled so as to place an operation point of the compressor within a high efficiency operation region by using a phase difference between each detected values (for example, a phase difference between the current and the voltage), and an operation frequency is varied according to a load variation, accordingly an operation efficiency of the compressor can be improved.
