摘要(Abstract):

针对空调变水量设计中常用的二次泵系统 ,利用典型负荷分布图对二次侧水泵的 4种配置形式进行年运行费用分析 ,利用技术经济方法对投资回收年限进行比较。结果表明 ,多泵并联变速运行空调水系统具有很好的节能优势
The annual operation cost(AOC) of four secondary pump configurations was analysed under the typical load profiles The payback years of multiple parallel variable speed pumping system was calculated using the techno-economic method.The conclusion analysis showed that the parallel pumping system is an energy efficient variable water volume(VWV) system.
