Air-conditioner for vehicle
A control part outputs a signal demanding an engine start when it is determined that a temperature of cooling water detected by a water temperature detector is lower than a threshold. In a normal state where conditioned-air is blown off to a predetermined seat and the other seats, the control part lowers the threshold according to an increase in a heat amount emitted from an auxiliary heating element based on the operating state of the auxiliary heating element.
