Title:
REFRIGERATION CYCLE DEVICE FOR VEHICLE AND ON-VEHICLE APPARATUS CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2023071628
Kind Code:
A
Abstract:
To reduce a stop frequency of a compressor, and to smoothly re-drive the compressor.SOLUTION: A refrigeration cycle device comprises: a compressor 21 driven by a gasoline engine 2; a heat radiator 22 for heat-radiating a refrigerant discharged from the compressor 21; a decompressor 23 for decompressing the refrigerant which is heat-radiated by the heat radiator 22; an evaporator 123 for evaporating the refrigerant which is decompressed by the decompression part 23; a pressure equalization part 28 for equalizing pressure by making a suction side and a discharge side of the compressor 21 communicate with each other; a pressure equalization valve 26 for opening and closing the pressure equalization part 28; and a control part 40 for controlling a magnet clutch for intermitting a drive force transmitted to the compressor 21 from the gasoline engine 2 and the pressure equalization valve 26. When a brake pedal is pedaled in, and the negative pressure of the intake air of the gasoline engine 2 is lower than a prescribed value, the control part 40 controls the magnet clutch so that the drive force from the gasoline engine 2 is blocked, and the compressor 21 is stopped, and valve-opens the pressure equalization valve 26 so as to make the suction side and the discharge side of the compressor 21 communicate with each other.SELECTED DRAWING: Figure 4
