Claims

[Scope of utility model registration request]

The air mix damper introduces a portion of the cold air cooled by the cooling system, heats it through a heater, mixes it with the rest of the cold air, and blows it out into the car.The system automatically controls the temperature inside the car to a predetermined temperature by controlling the air temperature inside the car and the outside air temperature. In addition, in the automobile air conditioner in which the operating command value of the cooling device is changed depending on the position of the air mix damper and the evaporator temperature or the evaporator blown air temperature of the cooling device, the air blowing direction into the vehicle interior is set to the upper layer of the vehicle interior. An air conditioning system for an automobile, comprising means for stopping hot water supply to the heater when the heater is turned off.
