            摘要:

            为了辨析各影响因素与综合能效间的关系,给出了计算系统综合能效的量纲一表达式。结果表明,能源转换技术水平、冷热电需求结构、本地可再生能源利用及系统配置方案是影响系统综合能效的关键因素。以夏季工况为例展示了如何通过综合能效分析确定系统配置方案,并给出了几种典型配置下的综合能效水平。

            Abstract:

            In order to analyse the relationship between the energy efficiency level and influencing factors, proposes a universal comprehensive efficiency formula for multi-energy system. The results show that energy conversion technical level, local renewable energy resource and system configuration are the key factors which can influence the energy efficiency. Then with the case study, illustrates the way to optimize multi-energy system design through energy efficiency analysis and proposes the energy efficiency levels of several typical configurations.
