广州某商场离心式冷水机组能耗分析与运行优化

Energy Consumption Analysis and Operation Optimization of Centrifugal Chillers for a Shopping Mall in Guangzhou

针对广州某商场集中空调系统节能改造需求,分析了空调系统中设备能耗及能效现状,选定系统中离心式冷水机组进行节能改造。通过对机组运行数据采集及分析,发现机组存在蒸发温度、电子膨胀阀开度控制异常等问题,结合现场实地机组测试,对机组节能运行提出建议。

In response to the energy-saving transformation needs of a centralized air-conditioning system in a shopping mall in Guangzhou,the energy consumption and energy efficiency of the equipment in the air-conditioning system were analyzed,and the centrifugal chiller in the system was selected for energy-saving transformation.Through the collection and analysis of unit operation data,it is found that the unit has problems such as evaporation temperature and electronic expansion valve opening control abnormality.Combined with on-site field unit tests,suggestions are made for energysaving operation of the unit.
