Abstract:
A method and a system for controlling peak power in a multi-air conditioner are provided to equally maintain cooling of a plurality of rooms and efficiently manage energy by turning on and off multi-compressors in accordance with total power energy and turning off all compressors if total power energy exceeds peak power energy. Peak power energy and reference power energy are predetermined at a central controller(S1). Usable power energy range is divided into certain ranges and multi-stage levels are predetermined by the certain ranges(S2). A compressor on/off command for each compressor is set to turn off some multi-compressors while turning on the rest of multi-compressors by levels(S3). The central controller calculates total power energy of a multi-air conditioner(S4). The central controller judges whether the calculated total power energy is above the predetermined peak power energy(S5). If so, the central controller turns off all compressors(S7). If not, the central controller judges the level of the reference power energy based on the calculated total power energy(S6). The central controller turns off some compressors related to the judged level while turning on the rest of compressors to supply compressed refrigerant to a plurality of indoor units through the operating compressors(S8).
