Title:
VEHICLE AIR-CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/002370
Kind Code:
A1
Abstract:
This vehicle air-conditioning device is provided with: a blower (23) that blows out from a blowout opening into a vehicle cabin; a refrigeration cycle (40, 340) that circulates a refrigerant by means of an electric compressor; an interior heat exchanger (24, 26) that is provided to the refrigeration cycle, and that exchanges heat between the blown air resulting from the blower and the refrigerant; an inside/outside air adjustment device (22) that adjusts the fractions of inside air and outside air included in the blown air; and a blowing control unit (65) that, when the temperature difference between the outside air temperature (Tam) and the target temperature (Tao) of the blowout air blown out from the blowout opening is less than a predetermined value, causes the operation of the blower while the electric compressor is in a halted state, and controls the operation of the inside/outside air adjustment device in a manner so that air containing at least outside air is blown out into the vehicle cabin. As a result, if Tao is a temperature close to Tam, the electric compressor is halted and air containing outside air is blown by means of the blower, and so the blowout air can be a temperature close to Tao while effecting a reduction in power consumption.
