摘要
首先介绍了建筑物多联供系统传统技术评价指标,针对燃料电池联供系统的部分负荷优势,指出了传统的技术评价指标不能体现系统的年运行工况、运行时间的不足,提出了动态评价指标这一概念,将传统的静态技术评价指标改进为动态第一定律效率和动态第二定律效率两类指标,并在此基础上提出了年一次能耗因子和年二次能耗因子两个新指标,进而对FC-CCHP系统的地区适用性进行了分析,结果表明:运用新的技术评价指标可以更合理、准确地评价系统的性能,且所提出的技术评价指标亦具有一定的外延性,可以运用到以其他发电设备为原动机的建筑冷热电联供系统中,为建筑联供系统的合理科学评价提供了理论指导。
Firstly, the conventional technical evaluation index were introduced and it＇ s insufficiency was indicated, and then, the concept of dynamic evaluation method was proposed which could describe the fuel cell part load advantages. The conventional index was ameliorated to dynamic first law efficiency and dynamic second law efficiency , and the annual primary energy gene and annual second energy gene were defined, and the applicability was analyzed in different region, the results indicate that the new technical index could evaluate the system more correctly, and the technical evaluation index could be used to cogeneration system powered by other electric generation devices. The research work can be used as the guidance for scientific and reachable evaluation of cogeneration systems.
