摘要
在国家建筑节能设计标准中的耗电输热比HER的基础上结合一次能耗率和分析方法引申得到一次能源消耗输热比法PEHR和比法ER,并根据对电动水源热泵区域供热系统PEHR和ER指标的不同控制要求,得到了系统的最大作用范围.热水的供回水温差越小,PEHR和ER值越大,系统的最大作用范围越小.当热泵制热性能系数和热泵供水温差一定时,PEHR和ER的控制值越大,电动热泵的作用范围也越大,相同PEHR和ER的控制值时,a值越大,系统的供热范围越小.
On the basis of the ratio of electricity consumption to transferred heat quantity （EHR） propagated in the national building energy efficiency design standard, combining pri- mary energy consumption rate and exegetic analysis methods, the index of primary energy consumption ratio of heating supplied （PEHR） and exegetic ratio （ER） were established. According to the requirements of the control PEHR and ER indexes of the water source heat pump district heating system driven by electricity, the maximum heating range was obtained. The results showed that PEHR and ER control values increase with the decrease of the supply and return hot water temperature difference and cause the heating range decrease, when the coefficient of the heat pump and the supply and return hot water temperature difference are certain, the greater PEHR and ER control values, the more extensive reasonable heating range. The heating range will get smaller when the value a increase under certain PEHR and ER control values.
