【摘要】 对北京建筑工程学院新校区供热负荷及其变化规律进行了分析与计算,对不同的热源方案进行优化选择.针对高校不同功能的建筑在采暖时间上的差异,采用分时分区、二级泵变频的供暖方式,在无人停留时段采取值班采暖模式.分析表明,分时分区、变频供热能获取显著的节能效果,从而提高学校集中供热系统的经济效益、环境效益.更多还原

【Abstract】 The heating load of BUCEA and its variation are calculated and analysed,and the different heat source programs are selected in the paper.Because different functions of the university buildings have different heating time,the time-sharing partitions,the frequency heating method,and the heating mode in very few users time are used.Analysis showed that taking the time-sharing district,frequency conversion heating method could obtain significant energy savings and increase the economic and environmental benefits of the central heating systems in universities.更多还原
