摘要
建筑冷热电联供系统(又名分布式能源)通常以能源综合利用率来评价它的节能特性。行业标准《燃气冷热电三联供工程技术规程》也明确规定系统平均能源综合利用率应大于70%。然而,由于各种原因,分布式能源系统有时达不到上述要求。本文分析了分布式能源烟气温度对余热利用的影响及如何提高分布式能源的能源综合利用率。
CCHP system （Distributed Energy System /Combined Cooling, Heating and Power） is usually evaluated on its energy-saving features by comprehensive energy utilization. Industry standard 〈gas combined cooling heating and power supply engineering and technical regulations〉 also clearly defined that average systematic comprehensive energy utilization is above 70%. But distributed energy system can＇t meet the above requirements due to all kinds of factors. The article analyzes distributed energy flue gas temperature＇s impact on waste heat utilization and discusses how to improve comprehensive energy utilization in CCHP system.
