VEHICLE AIR CONDITIONING DEVICE

PROBLEM TO BE SOLVED: To reduce the operating frequency that operates an internal combustion engine in order to raise temperature of cooling water in a vehicle air conditioning device applied to a hybrid vehicle.SOLUTION: When operating an engine EG in order to raise the temperature of the cooling water used as a heat source of a heater core until it becomes engine-off water temperature Twoff, the engine EG engine-off water temperature Twoff for the EV operation mode in which the motor side drive force output from an electric motor for running becomes larger than the internal combustion engine side drive force output from the internal combustion, is set to the temperature lower than that for the HV operation mode to which the motor side drive force becomes smaller than the internal combustion engine side drive force. Thereby, the operating frequency of the internal combustion engine EG is reduced by making it easy to stop the engine EG.
