摘　　要：某采用磁悬浮空调制冷机组制冷的中央空调系统在冷负荷增加条件下加载启动机组时,存在系统功率突增和突降现象。本文通过分析机组和输配系统各组成部分耗电功率及系统效率的变化情况,同时对比实验模拟工况,分析项目现场运行逻辑和控制的合理性,给出精细化运行调节方案。The studied central air conditioning system that uses magnetic levitation air conditioning refrigeration units experienced sudden increase and decrease of system power when the start-up unit is loaded under the condition of increasing cooling load.This paper analyzed the variations in power consumption and system efficiency of each component of the unit and transmission and distribution system,and compared the simulated working conditions of the experiment.In addition,the rationality of the operation logic and control of the project site was analyzed,ultimately providing a refined operating adjustment scheme.
