Abstract

The present invention discloses an operation control method for a unitary air conditioner. The present invention improves the load response capabilities of compressors by operating them at three-stages of the maximum operation, minimum operation and intermediate operation using one or more compressors, and improves the energy efficiency and the amenity by determining the three-stage operation mode based on the previous operation status.
