Abstract
In a control unit of a vehicle air conditioner, a necessary time period T between the present time and a time at which the vehicle is stopped next, and a vehicle stopping time period T between the time at which the vehicle is stopped next and a time at which the vehicle is re-started, are estimated based on vehicle-travel state information and traffic signal information in a vehicle traveling. Further, a necessary cold release amount Q required for cooling in the vehicle stopping time period T is calculated based on the vehicle stopping time period T and a cold storage operation is controlled so that the necessary cold release amount Q is stored for the necessary time period T
