Title:
VEHICULAR AIR-CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/146269
Kind Code:
A1
Abstract:
The purpose of the present invention is to achieve agreeable and efficient in-cabin dehumidification heating, even in cases when a dehumidifying circuit which bypasses an external expansion valve and an outdoor heat exchanger is not provided. The present invention is provided with: a compressor 2; a radiator 4; a heat absorber 9; an outdoor heat exchanger 7; a bypass device 45 which causes a refrigerant discharged from the compressor to flow directly into the outdoor heat exchanger without flowing through the radiator; an auxiliary heater 23; and a controller. The controller implements at least a dehumidification heating mode in which the bypass device 45 is used to cause the refrigerant discharged from the compressor 2 to flow to the outdoor heat exchanger 7 and release heat, the refrigerant from which heat is released is decompressed, and, thereafter, the heat absorber 9 is made to absorb heat, and the auxiliary heater 23 is made to generate heat.
