摘要
运用以电量为基准的供热过程的性能评价指标,建立了热电联产供热到用户的当量性能系数(ECOP)和供热煤耗率(b_h)的通用数学模型。对应分析比较其他供热方式,进行了实例计算分析,结果表明热电联产供热在合理供热半径内有很好的节能效果。在远离热电厂的地区,热泵供热更合理。
According to the index of evaluating performance of heat supply based on electricity, this paper presents general mathmatics models of equivalent cofficient of performance (ECOP) and fuel consumption rate of heat supply (b_h) which can be calculated from CHP plant to users. The paper analyzes and compares width various heating processes. The results show that cogeneration heating system will have the excellent energy-saving effect in the reasonable radius of heat supply. But far from CHP plant, heat pump is better.
