Title:
VEHICULAR AIR-CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/138272
Kind Code:
A1
Abstract:
Provided is a vehicular air-conditioning device which is capable of preventing occupants from feeling cold when the flow rate of a heat medium flowing through a heating heat exchanger is low. This vehicular air-conditioning device is provided with: a casing (31); a heating heat exchanger (36); a flow rate adjustment unit (40a); an air flow rate adjustment unit (32); blow-out mode switching units (24a, 25a); and a control unit (50). The casing is provided with an air passage, a face blow-out port (24), and a foot blow-out port (25). The heating heat exchanger causes heat to be exchanged between air and a heat medium for cooling an engine (EG), to heat the air. The flow rate adjustment unit adjusts the flow rate of the heat medium flowing through the heating heat exchanger. The air flow rate adjustment unit adjusts the flow rate of the air flowing through the air passage. The blow-out mode switching units switch between a face mode and a non-face mode. The control unit determines, on the basis of a target blow-out temperature (TAO), the flow rate of the air flowing through the air passage, and controls operation of the air flow rate adjustment unit, and, in cases when the blow-out mode switching units are executing the face mode, and the flow rate of the heat medium flowing through the heating heat exchanger is equal to or less than a prescribed value, corrects, towards the reduction side, the flow rate of the air flowing through the air passage.
