Abstract
An air conditioning apparatus for an automobile having a compartment comprises a cooling unit including an evaporator for cooling air, a heater for heating a portion of the cooled air, an air mixing damper for mixing the cooled air with the heated portion thereof and introducing the mixture into the compartment of the automobile, a control device for controlling the air mixing damper based on temperatures inside and outside of the compartment to keep the former at a constant temperature, a variable resistor connected operatively to the air mixing damper, and a temperature detector for detecting the temperature of the evaporator or the temperature of the cooled air supplied therefrom, the control device being responsive to an output of the variable resistor and the temperature detector for changing an operation command signal for the cooling unit.
