冷热电联产系统性能评价指标研究

Studying of Evaluation Methods of Combined Cold,Heat and Power System

根据冷热电联产系统的供能特点,在比较分析联产系统性能评价指标的基础上,提出了用当量电效率来评价联产系统的性能的方法。文章用一次能源利用率、火用效率和当量电效率对冷热电联产系统的性能进行了分析,结果表明当量电效率具有合理、可行性和简单实用的特点。

Equivalent power efficiency was established to evaluate the performance of Combined Cold, Heat and Power （CCHP） system according to energy supply of CCHP, based on the analysis of different evaluation methods for CCHP. Primary Energy Rate （PER）, exergy efficiency and equivalent power efficiency were used to evaluate the performance of a combined cold, heat and power system. The results show that the evaluation method of equivalent power efficiency is feasible and simple.
