Title:
VEHICLE AIR-CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/054041
Kind Code:
A1
Abstract:
The present invention provides a vehicle air-conditioning device capable of smoothly realizing pre-air-conditioning for preliminary warming the inside of a cabin while completely or as much as possible preventing frost deposition on an outdoor heat exchanger. When performing pre-air-conditioning for preliminary warming the inside of a cabin before passenger boarding, if the temperature of a battery 55 or a traveling motor 65 is equal to or higher than a prescribed value, a controller 32 operates a compressor 2, causes a radiator 4 to radiate heat from a refrigerant discharged from the compressor, reduces the pressure of the refrigerant having radiated heat, and then causes a waste heat recovery heat exchanger 64 to absorb heat without using an outdoor heat exchanger 7 to warm the inside of the cabin.
