Abstract

PURPOSE: To improve power efficiency and reduce drastically power consumption by setting an operation of a pole converter of a motor having a simple and low cost constitution and a position of a slide valve responding to the operation of the converter and by performing volume control.
CONSTITUTION: When performing volume control, a compressor is operated by a slide valve 4, if it remains in a voluminous operating region, under the control of a fluid pressure valve of a slide valve drive unit 5 operated by pulses emitted from an indicator provided with a compressor. When the operation comes to a specified operating range of small volume, a pole converter of a motor shifts poles and reduces the number of revolution and sets the slide valve 4 to meet the above performance and controls the volume by the slide valve 4. Application of this simple and low cost construction makes its possible to perform extensive volume control with ease. The volume control then prevents a rapid increase in power as well as worsening of power efficiency.
