Abstract
Disclosed are an apparatus and a method for controlling the operation of an air conditioner, in which one or more compressors are operated so that the total refrigerant compression capacity of the operating compressors is variably changed according to a cooling or heating load to be eliminated, and an opening degree of an electronic expansion valve is controlled between minimum and maximum values set according to the total refrigerant compression capacity of the operating compressors, thus stably operating the air conditioner and preventing the refrigerant in a liquid state from being introduced into the compressors and the compressors from overheating.
