Abstract

PURPOSE: To improve operation capacity and reduce power consumption by linking the compression capacity change of a compressor with variable compression capacity and the revolution number of a motor with a variable revolution as well as by so forming that the optimum motor characteristics for each load can be obtained.
CONSTITUTION: While normal operation, a link 26 of a switching mechanism connects a high speed terminal H and an open terminal K of compression motor 23 with a power source and the motor 23 operates at high speed while the compressor 10 performs a constant load operation. After adequate time operation of the system, when a detector and the like senses a reduced load, the switching mechanism changes over to connect a low speed terminal L as well as an electromagnetic terminal V with the power source. Then the motor 23 operates at low speed while the compressor performs a bypass operation. In this way, by providing the switching mechanism, which links the compression capacity change of compressor with the motor revolution number, the most suitable motor characteristics to a high-or-low load operation respectively can be obtained.
