PAGE 天津市天馨苑小区36#楼采暖工程设计 Heating Project design for No.36 Building in Tianxinyuan District of Tianjin 摘 要 本次设计为天津市天馨苑小区36#楼采暖工程设计和小区换热站工艺设计。其中采暖设计包括热负荷计算，采暖系统方案的确定和采暖系统水力计算；换热站设计包括换热站规模的确定、设备的选型计算和换热站的工艺布置及相关计算。36#楼的建筑面积为7863㎡，采暖热负荷114kW，采暖系统形式为地板辐射采暖，热媒设计参数为45/35℃，户内盘管管材选用管径为20mm的聚丁烯（PB）管。换热站供热规模为13万㎡，设计总负荷为4.2MW。一次热网热水由地热供热站提供，设计参数为71/38℃，二次网热水参数为温度45/35℃。换热站内设置两组BBR50型板式换热器，每组承担70%的总热负荷；循环水泵选择三台，型号为KL(W)-125-160A，两用一备；补水泵选择两台，型号为KL(W)-40-125。在设计过程中，查阅了大量的参考资料，采用了目前常用的设备和新的技术，并对建筑节能给予关注。 关键词：集中供热；地板辐射采暖；换热站；设计 ABSTRACT It is a design for Tianjin tianxinyuan 36 # Building heating engineering ,including the design for the Tianjin tianxinyuan 36 # Building heating project and district heating exchange station, The heating design contains heating heat load calculations, heating systems and the heating systems to determine the program of hydraulic calculation; Heat exchange station design takes brief introdunction ,exchange station equipment selection, process of calculation and heat transfer station layout and calculations. 36 # floor covers the area of 4732 square meters, heating loads of 100kW, thermal media set parameters of 45/35 ℃, heating system in the form of radiant floor heating, pipe diameter is 12mm. The total heat load of station design is 4.2MW, heat transfer area covers 12 million square meters, the heating network design parameters for the heating medium is 71/38 ℃, the second network parameters for the heating medium temperature is 45/35 ℃. Heat transfer stations choose two type BBR50 plate heat exchanger from energy-saving Equipment Co. Ltd Beijing Hua Yixin, each takes 70% of the heat load; three KL(W)-125-160A-type circulating pump from Kaili water pump, two KL(W)-40-125-type pumps from Kaili Third Pump. In design process,I have looked up a large number of references, using the commonly used equipment and new technology, Key words: central heating; floor heating system; heat exchange station; design 目 录 TOC \o 1-2 \h \z \u 第
