Abstract

PURPOSE:To stabilize blowoff air flow in an air conditioner with a built-in microcomputer by obtaining the voltage applied blower motor depending upon the input temperature and increasing and decreasing supply current based on the differential voltage between the voltage applied on the blower motor and the actually applied voltage. CONSTITUTION:Signals from a temperature setting section 7, an inner air sensor 8, and an outer air sensor 9 are input into a microcomputer 6 to carry out the specified operation so that a negative control means 10, a hot water valve 11, and a compressor 12 may be controlled. Then, the preset voltage VMS of a blower motor 5 is computed. Subsequently, the voltage actually applied on the blower 5 is obtained from the positive and negative potential terminal voltage VMP and VMN of the blower motor 5 and the difference between this actually applied voltage and preset voltage is computed. Based on this result, the base current of a power transistor 4 is increased and decreased through an output port 18 and an arithmetic amplifier 13 and the supply current to the blower motor 5 is controlled. As a result, the number of revolutions of the blower motor 5 can be stabilized.
