PURPOSE:To prevent a sudden change of a discharge temperature, by a method wherein, during turning ON and OFF of a compressor, the opening of an air mix door is corrected in response to a duct air temperature by means of a correction amount responding to the opening of the air mix door. CONSTITUTION:An air temperature on the downstream of a vaporizer 6 from a duct sensor 14, a car room temperature from a car room temperature sensor 15, an open air temperature from an open air temperature sensor 16, a solar radiation amount from a solar radiation sensor 17, a set temperature from a temperature setter 18, and the opening of an air mix door 9 from an opening sensor 19 are inputted to a microcomputer 20 through a multiplexer 21. The microcomputer 20 computes and processes in a given order to decide a correction amount of the opening of the air mix door to compensate for a change in an duct temperature due to turning ON and OFF of a compressor 8. The correction amount is decided according to the opening of the air mix door 9. This constitution enable prevention of a sudden change in a discharge temperature occasioned by a change in a using condition. |
