Title:
VAPOR COMPRESSION REFRIGERATION CYCLE
Document Type and Number:
Japanese Patent JP2000065430
Kind Code:
A
Abstract:
To prevent a compressor from operating unnecessary work when the compressor restarts.
When an electromagnetic clutch 110 is turned off to stop operation of a compressor 100, energizing a pressure regulating valve 400 is discontinued, and the pressure regulating valve 400 is allowed to operate as a normal closed, (closed at a non-energized time) proportional pressure reducing solenoid valve. Thereby a pressure (a pressure of a higher-pressure side) of a side of a radiator 200 is prevented from reducing during stoppage of the compressor 100, and the compressor 100 is prevented from operating unnecessary work when the compressor 100 restarts.
