Apparatus and method for controlling compressors of air conditioner

Abstract

Disclosed are an apparatus and a method for controlling a plurality of compressors of an air conditioner. The apparatus comprises a counter, a timer, and a controller. The counter serves to count the number of times of operations/stoppages of the plural compressors according to loads. The timer serves to sense a time taken for the plural compressors to be operated/stopped a designated number of times counted by the counter. The controller serves to control the operations of the plural compressors based on the time sensed by the timer. The apparatus senses the time taken for the plural compressors to be operated/stopped the designated number of times, and determines whether or not a load is eliminated based on the sensed time, thereby properly controlling the operations of the compressors. Accordingly, the apparatus of the present invention reduces the consumption of power and increases air conditioning efficiency of the compressors.
