Abstract

PURPOSE:To prevent a feeling from uncomfortableness through a change of air flow amount, by providing a rotational speed control method to control a rotational speed of the blower drive motor so as to change a blowout air flow rate by stages in accordance with a decision of the decision unit. CONSTITUTION:A deviation from the reference input from a slide resistor 11 corresponding to the set temperature is converted by a comparator unit 31 into an absolute value of potential difference across d-e, with its deviation signal fed to a decision unit 32. In the decision unit 32, a potential at a divided point f by a resistor 39, 40 is compared with the deviation signal in a comparator 43, and a potential at a divided point g by a resistor 41, 42 is compared with the deviation signal in a comparator 44. A change of this potential is amplified by a transistor 49, with an input fed to a conrol transistor 33 connected to the circuit of a blower driving motor 9. And by changing a voltage applied to the motor 9, a rotational speed of the motor is changed to change a blowout air flow rate.
