关于多次泵冷水系统输送能效比计算及评判的探讨

The Discussion on the calculation and Evaluation about the energy efficient ratio of cool water transportation system by the multiple pumps

本文就<《公共建筑节能设计标准》广东省实施细则>(DBJ15-51-2007)中冷水系统输送能效比的计算公式不能满足复杂系统输送能效比的计算,结合工程实例,介绍了多级泵系统输送能效比的计算方法及判定依据。

The formula for calculation the energy efficient ratio of cool water transportation system could not satisfy the complex system in the< Implementation of《Design standard for energy efficiency of public buildings》in Guangdong Province>(DBJ15-51-2007),in this paper,with an engineering example,introduced the calculation and evaluation about the energy efficient ratio of the multi-stage pump.
