Abstract

PURPOSE: To improve the drive efficiency of a compressor, by reducing the revolution speed of a prime mover to a level at the lower-limit point matching of the compressor in its high capacity control stage and by thereafter controlling the capacity of the compressor by stages.
CONSTITUTION: The revolution speed of a prime mover is reduced from a point of matching (revolution speed N1.1) with the maximum output A of the prime mover at the entire capacity of a compressor, to diminish the capacity of the compressor along its entire-capacity performance line B. As soon as the prime mover has reached a revolution speed N1.2 at the lower-limit point of matching at the entire capacity of the compressor, the prime mover is accelerated and the capacity of the compressor is set at (n-1)n×100 per cent. According to such a method, the high range of capacity of the compressor can be controlled in a stepless manner. For that reason, the compressor can be efficiently driven.
