一次泵/二次泵变流量系统能耗分析

Energy consumption analysis of primary pump and primary-secondary pump systems with variable flow rate

以上海通用汽车有限公司制冷站为例,比较了一次泵和二次泵变流量系统的能耗,结果表明,一次泵系统的耗电量仅为二次泵系统的68%。

Taking the refrigeration station of Shanghai GM Co. Ltd. as an example, compares the energy consumption between primary pump and primary-secondary pump systems with variable flow rate. The result shows that the electricity consumption of primary pump system is only 68% of that of the primary-secondary pump system.
