摘要
建立了二次泵变流量空调冷水系统输送能耗及输送能效比的计算模型。以成都地铁4号线某集中冷站为工程实例,针对不同的二次环路设置方案,分别计算分析其冷水系统的全年输送能耗值及其输送能效比。结果表明,按照地铁车站输送管道阻力大小分别设置二次环路相对于沿集中冷站向隧道两端各设置一个二次环路的方案,其冷水系统全年输送能耗的节省率为24.75%,输送能效比降低率为32.48%。
A calculation model of pumping energy consump- tion and pumping energy efficiency ratio of variable volume in the secondary pump water system is established. One central cooling station on Chendu metro Line 4 is taken as an example, the annual energy consumption and energy efficiency ratio are calculated under different strategies of secondary circuits. The result shows that the annual pumping energy consumption is about 24.75% when the secondary circuits are set separately on both ends of the tunnel, and the decrement pumping energy efficiency ratio is about 32. 48%.
