Title:
REFRIGERATION CYCLE DEVICE FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/235414
Kind Code:
A1
Abstract:
The purpose of the present invention is to ensure as much air cooling capacity and battery cooling capacity as possible. A control unit (50) can switch between second evaporator priority control for controlling the throttle opening of a second expansion valve (15) on the basis of the refrigerant state of a second evaporator (16) and first evaporator priority control for controlling the throttle opening of the second expansion valve (15) on the basis of the temperature of a first evaporator (14), the temperature of the refrigerant flowing through the first evaporator (14), and/or the temperature of the air heat-exchanged in the first evaporator (14). In the second evaporator priority control, the control unit (50) switches to first evaporator priority control when the temperature of the first evaporator (14), the temperature of the refrigerant flowing through the first evaporator (14), and/or the temperature of the air subjected to heat exchange in the first evaporator (14) becomes equal to or higher than a switching temperature.
