Abstract
A refrigeration cycle device for a vehicle has a compressor, a first pump, a high-pressure side heat exchanger, a heating medium-outside air heat exchanger, and a controller. The compressor draws and discharges a refrigerant. The first pump draws and discharges a first heating medium. The high-pressure side heat exchanger heats the first heating medium by exchanging heat between a high-pressure refrigerant discharged from the compressor and the first heating medium. The heating medium-outside air heat exchanger exchanges heat between the first heating medium and outside air. The controller controls operation of the compressor and the first pump. The controller activates the first pump when an activation request of the compressor is made. The controller activates the compressor, after activating the first pump, when it is determined or estimated that a temperature of the first heating medium is lower than or equal to a first predetermined value.
