Title:
VEHICULAR AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2020/149064
Kind Code:
A1
Abstract:
[Problem] To provide a vehicular air conditioner with which it is possible to suitably control the valve opening degrees of each of a plurality of expansion valves, thereby improving responsiveness of the control. [Solution] When the temperature detected by a heating-air temperature sensor is lower than a targeted temperature, a controller adjusts a first expansion valve 23a so that the valve opening degree thereof decreases, and when the temperature detected by the heating-air temperature sensor is lower than the targeted temperature in a state in which the valve opening degree of the first expansion valve 23a has been minimized within a set range, the controller adjusts a second expansion valve 23b so that the valve opening degree thereof increases.
