Claims

[Scope of utility model registration request]

It has an air blowing means, a cooling means, a heating means, and a means for detecting the air temperature inside the vehicle, and controls the air blowing means based on at least the temperature difference between the target temperature and the air temperature inside the vehicle in order to achieve a given target temperature. In the air conditioner for an automobile, the larger the heat load detected by the heat load detection means of the air conditioner including the outside air temperature detection means, the steeper the change gradient of the air volume with respect to the change in the temperature difference in the air blowing means control. An air conditioner for an automobile, characterized in that the air volume is controlled by increasing the temperature difference, or by increasing an addition term for air volume calculation with respect to the temperature difference.
