PURPOSE:To perform delicate control of an air mix damper by a method wherein the opening of an air mix damper is determined by means of a discharge air temperature computed by means of a temperature in a car room and an atmosphere temperature, and the opening signal is corrected by means of a preset correction value. CONSTITUTION:Through detection of a temperature in a car room and an atmosphere temperature by means of sensors 8 and 9, respectively, a necessary discharge temperature is computed by a necessary discharge air temperature computing means 10. An air mix damper(AMD) opening computing means 11 calculates the opening of an air mix damper 7 based on a necessary discharge air temperature. A correction means 12 corrects the calculated opening by means of a correction value so that characteristics are adjusted to a value approximately equal to a prestored ideal value. By means of the corrected target opening, an AMD drive means 13 drives and controls the air mix damper 7. This constitution adjusts characteristics to a value approximately equal to an ideal value to perform delicate control. |
