摘要
分布式冷热电联供系统的性能与用户的负荷特征存在密切关系,因此需要遴选与系统互动性较好的典型用户,以使分布式系统具有较好的运行效果。本文从理论上提炼了用户的3个遴选参数,并研究其影响,结果表明一般来说,负荷率、匹配系数越接近于1,冷负荷占比越小,用户使用分布式系统的节能性越好。基于3个遴选参数,本文制定了典型用户的遴选方法。借助Designbuilder软件,对我国各个气候地区各种功能的建筑进行负荷模拟,运用遴选方法最终遴选出的典型用户为北京医院、哈尔滨宾馆、上海医院、香港宾馆、香港医院。
The performance of the CCHP system is closely related to the user’s load characteristics.Therefore,it is necessary to screen typical users with good interaction with the system so that the system has a better operation effect.This paper theoretically abstracts 3 user’s selection parameters and studies their impact.The results show that in general,the closer the load factor and the matching coefficient are to 1,and the smaller the cooling load ratio,the better the energy efficiency of users using CCHP systems.Based on the three selection parameters,this paper has developed a typical user screening method.With the aid of Designbuilder software,this paper carries out load simulation of various functional buildings in various climate regions in China.And typical users selected by screening methods are Beijing Hospital,Harbin Hotel,Shanghai Hospital,Hong Kong Hotel,and Hong Kong Hospital.
