热水供暖供热系统耗电输热比应用探讨

Use of an energy efficiency index in hot water heating systems

分析了热水供暖供热系统的节能指标———耗电输热比 (EHR)应用中的若干问题 ,给出了适用于多种热源和热用户形式的EHR理论值的计算公式 ,以及针对不同的设计供回水温差及循环水泵效率的修正系数。

Analyses some issues in practice of using EHR, an index indicating the electric power consumed for transporting a unit of heat amount, provides a formula for predicting its values under design conditions for diversified heat sources and heat users and their correction factors for the temperature differences between supply and return water and for the pump efficiency.
