Abstract

PURPOSE:To permit rotational frequency of a blower motor to accurately correspond to the opening of an air mix door by controlling the rotational frequency of the blower moter according to control signals of the opening of the air mix door computed by a microcomputer of an air conditioner for an automobile. CONSTITUTION:Indoor temperature 2, outdoor one 3 and set one 4 are applied through a multiplexer 22 to the input of a microcomputer 16 to compute the dispersion value, determine a value for controlling the opening of an air mix door 12 and drive a switch valve 26 and a three-way vavle 26. On the other hand, in CPU19, revolutional speed of a blower motor 13 corresponding to the opening of the air mix door 12 is figured out to send output signals for controllably driving the blower motor 13 to a blower driving circuit 24. Thus, the speed of the blower motor 13 is adapted to correspond to the opening of the air mix door accurately.
