Document Type and Number:
WIPO Patent Application WO/2023/182759
Kind Code:
A1
Abstract:
The present invention relates to an air conditioning device for a vehicle. The purpose of the present invention is to improve the structure and air flow structure of a heat exchanger for heating and thereby reduce the electrical consumption of the heat exchanger for heating without reducing the comfort of the vehicle interior, and to differentiate the temperature of air discharged to the upper and lower sides of the vehicle interior. In order to achieve the above purpose, the present invention provides an air conditioning device for a vehicle, the air conditioning device comprising: a heat exchanger for cooling and a heat exchanger for heating which are sequentially installed on an internal flow path of an air conditioning case and cool and heat the discharged air of a blower; and a plurality of air discharge ports for discharging, to the vehicle interior, cold and hot air that has passed through the heat exchanger for cooling and the heat exchanger for heating. The air conditioning device is provided with: a first bypass flow path through which the blower-side discharged air that has yet to pass through the heat exchanger for cooling is bypassed to the upstream side of the heat exchanger for heating; and a first opening/closing door for opening and closing the first bypass flow path.
