Claims

[Scope of utility model registration request]

The air that has passed through the cooling system is separated by an air mix damper into warm air that is obtained by passing through a heater that uses hot water as a heat source, and cold air that bypasses the heater, and then the two are mixed and blown into the vehicle at an appropriate temperature. In addition, the air mix damper is automatically controlled according to the temperature inside the car and the outside temperature to maintain the temperature inside the car at a set value,
An air conditioner for an automobile characterized in that a temperature detector is provided to detect the temperature of the hot water flowing into the heater, and the air mix damper is moved to a cool side or a hot side depending on whether the temperature of the hot water is high or low. Device.
