Abstract
A method for controlling multiple compressors for use in an airconditioner is disclosed. In the airconditioner having N compressors, the method sequentially and equally operates the N compressors using a two-dimensional matrix which prevents only a specific compressor from among the N compressors from being repeatedly operated, arranges rows and columns of the two-dimensional matrix to allow all compressors to be alternately operated according to the number of operating compressors from among all compressors, and stochastically operates and stops the N compressors using the two-dimensional matrix. As a result, the method controls the N compressors to be equally operated without overlapping operation times of the N compressors, and alleviates fatigue of the compressors, resulting in equally longer lifetimes of the N compressors.
