楼宇型冷热电联供系统设计及实例分析

摘要

楼宇型冷热电联供作为建筑物新的供能系统,其有效地提高了一次能源的利用率,实现了节能减排.以湘潭市某宾馆为例,结合建筑用能需求,根据各种负荷的年负荷延续图进行冷热电联供系统配置设计,简要介绍了楼宇型冷热电联供系统的特征和设备组成,并分析了联供系统的经济性.分析结果表明,小型楼宇冷热电联供系统节能环保效果明显,具有较好的环境效益和社会效益,但在当前的市场条件下,联供系统的投资回收期较长.%Taking a hotal in Xiangtan as example,this paper briefly introduces the characteristics and equipment components of buildings type combined cooling,heating and power(CCHP) system.Combined with building energy demand,it discusses the method of CCHP system configuration from the thermoelectric ratio,operation mode and economic efficiency.In the end,a CCHP system solution is designed,and the economic efficiency of the system is analyzed.
