1、 摘 要 随着我国城市建设事业的发展，以及国家对于能源与环境保护的要求，供暖系统的规模从单幢采暖系统发展成为中大型区域集中供暖系统，出现了大量住宅，公共建筑的集中供暖系统。集中供暖在节能和坏境保护方面都有很大的优势，发展速度很快。 本设计题目为青海省西宁市世家馨城综合楼的集中供暖设计，在设计中 包括室内外设计参数的确定、供暖热负荷的计算、供暖系统方案的选定、散热器类型的选定及供暖系统水力计算。 选择供热系统需要的各种必要的设备和水泵等。整个设计严格按照规范，充分考虑技术，经济同时关注节能，使整个热网有一个较高 的效率。 关键词： 区域供热 ,热负荷 ,散热器 ,热网，系统 ABSTRACT W
2、ith the city constructs developing and energy save and environment require,the heating systems have changed from single heating to district heating.So many district heating system come out in many north cities in China. My design title is the heating network designing of xining .In this design ,manu
3、al of heating system mainly includes indoor and outdor parameters,calculation of heat load,choice of heating system,decision of the type of radiator and definite diameters of water pipe through calculation of water power. I choose the basic equipment such as bump,heat exchanger with these calculatings.In my design, I supply some districts with hot water .All the designs have a stict to the bans,considering the and enconme and energy save,in order to make the network be a high efficient.
