An apparatus and method for controlling an air conditioner capable of reducing a fabrication cost by using one high-speed microcomputer and one port-ex-tension microcomputer, enhancing a reliability thereof by reducing a data communication amount between the microcomputers, and implementing a simple circuit construction. The apparatus for controlling an air conditioner comprising: a converter for converting an alternating current voltage (ACV) into a direct current voltage (DCV), and boosting the DCV; a smoothening unit for smoothening the DCV from the converter; an inverter for converting the smoothened DCV into an ACV; and a motor, comprises: a supplementary microcomputer for controlling a valve for controlling a refrigerant flow inside a pipe of the air conditioner and a relay for controlling a current flow by receiving a control signal; and a main microcomputer for entirely controlling the air conditioner with the real-time controlling unit of the air conditioner and the supplementary microcomputer. |
