PURPOSE:To stabilize the blowout temperature characteristics by suppressing the opening change rate of an air mix door against the change of an integrated signal when the air mix door is rotated in the full heat mode direction. CONSTITUTION:When an integrated signal T exceeds a preset value, the comparing means 81 of a change rate suppressing means 80 detects it and outputs a signal to a gain outputting means 82. The gain outputting means 82 outputs the gain alpha to a multiplication circuit 83. The multiplication circuit 83 multiplies the integrated signal T by the gain alpha, a signal suppressed from the integrated signal T by alpha is outputted to an air mix door control means 34, and the opening change rate of an air mix door 5 is suppressed. According to this constitution, the blowout temperature characteristics can be stabilized. |
