Title:
VEHICULAR AIR-CONDITIONING DEVICE, ELECTRIC COMPRESSOR, AND VEHICLE AIR-CONDITIONING METHOD
Document Type and Number:
WIPO Patent Application WO/2015/046194
Kind Code:
A1
Abstract:
A refrigerant heating capacity is increased while suppressing an increase in weight or cost. A vehicular air-conditioning device (10) is provided with a heat-pump cycle (16) for heating operation in which an electric compressor (50) for compressing refrigerant, a cabin interior condenser (26), a throttle valve (52), and a cabin exterior heat exchanger (54) are connected in that order via refrigerant piping. An inverter for the electric compressor (50) in which a power device comprising a highly heat-resistant semiconductor device is used is installed on the electric compressor (50) so that the refrigerant compressed by the electric compressor (50) can be heated by the power device. During heating operation of the heat-pump cycle (16), the refrigerant is heated by the power device.
