摘要
集中空调冷却水变流量是否节能存在争议,利用某项目高效空调自动控制系统构建在线实验比较平台,发现冷却水变流量系统的能效高于定流量系统;该项目实行变流量运行模式实际运行效果较好。借助制冷系统的自动控制平台对不同运行模式的能效进行比对的方法具有可行性。
It is controversial whether the variable volume cooling water system in central air conditioning saves energy. Builds an online experimental comparison platform by the high efficient air conditioning automatic control system of a project. The results show that the energy efficiency of variable volume cooling water system is higher than that of constant volume system and the actual operation effect of variable volume operation mode is better. It is feasible to compare the energy efficiency of different operation modes by the automatic control platform of the refrigeration system.
