Document Type and Number:
WIPO Patent Application WO/2019/150832
Kind Code:
A1
Abstract:
Provided is an air conditioning device for a vehicle, the device making it possible to perform efficient operation by further facilitating execution of a dehumidifying/heating mode if switching between the dehumidifying/heating mode and a dehumidifying/cooling mode. A heat pump controller executes transition to the dehumidifying/cooling mode if a prescribed dehumidifying/cooling transition condition has been established during operation in the dehumidifying/heating mode, and executes transition to the dehumidifying/heating mode if a prescribed dehumidifying/heating transition condition has been established during operation in the dehumidifying/cooling mode. If a prescribed fluctuation has occurred in an operation condition or an operation state during operation in the dehumidifying/cooling mode, the heat pump controller executes transition to the dehumidifying/heating mode regardless of whether the dehumidifying/heating transition condition has been established.
