供暖系统毕业论文

供暖系统毕业论文摘 要随着我国城市建设事业的进展，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进展成为中大型区域集中供热系统，出现了大量住宅，综合小区的集中供热系统。集中供热在节能和环保方面有很大的优势，得到了较快的进展。本设计题目为沈阳市某小区集中供热系统外网设计. 在设计中根据建筑物的热负荷，选择所需要的热源，然后进行管网的水力计算，确定外网的管径及阻力损失。同时选择供暖系统所需要的各种必要设备如水泵，换热器等。除此之外本设计中还考虑部分小区的生活热水的供应。整个设计严格根据法律规范，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 ； 外网设计； 热负荷； 节能AbstractWith the city construct’s 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 shenyang .In this design ,I choose the heat source by the heat load of buildings.As follow I do the network’hydrulic calculating to get the dimension of network and the flow resistance. I choose the baisic equipment such as bump ,heat exchanger with these calculatings. In my design ,I supply some districts with hot water.All the designs have a strict to the bans,considering the and enconme and energy save ,in order to make the network be a high efficient.Key words:district heating network design heat Load energy save 目 录摘 要...............................................................................................................1Abstract........................................................................................................................2第1 章 绪论.......................................................................................................6第2 章 小区热负荷计算.......................................................
