Title:
VEHICLE AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2015/159485
Kind Code:
A1
Abstract:
Provided is a vehicle air conditioner in which a dehumidifying and heating mode has an increased effective range with regard to environmental conditions and a vehicle interior can thus be smoothly dehumidified and heated. The vehicle air conditioner (1) uses a controller to execute a dehumidifying and heating mode wherein after a radiator (4) dissipates the heat of refrigerant discharged from a compressor (2) and the pressure of the heat-dissipated refrigerant has been reduced, the refrigerant absorbs heat at a heat absorber (9) and an outdoor heat exchanger (7). When the temperature (TCI) of the radiator (4) is under a satisfactory condition and the temperature (Te) of the heat absorber (9) is high even if the degree of opening of an outdoor expansion valve (6) is set to a lower control limit, the controller lowers the outdoor fan voltage (FANVout) of an outdoor fan (15) and decreases the volume of air of the outdoor fan (15).
