1、I 摘 要 关键词： 采暖 给水 排水 消防 设计 此项设计为沈阳市某办公楼楼室内采暖、给排水系统工程设计，题目来源于 实际工程 ,目的在于通过合理的设计使该建筑达到为人们提供舒适的生活和工 作环境。 该建筑为六层建筑。采暖系统设计设置了一个系统。为了使系统水环路的水 力平衡易于调节,采用上供下回同程式。采暖系统设计包括：首先对此建筑物进 行采暖热负荷计算，然后合理选择散热器并进行系统水力计算， 水力计算采用等 温降法,最后确定此系统的循环水量和入口压差，满足室内温度的要求。 建筑内部给水系统分为生活给水系统和消防给水系统。 生活给水系统采用下 行上给式，通过设计秒流量和系统水力计算，确定各管
2、段的管径使入口处的水量 和水压达到使用要求。该建筑为多层建筑，根据建筑物的性质按消防规范要求， 合理布置室内消火栓。消火栓给水系统设了两个入口及两个消防水泵接合器，同 时设消防水箱并贮存 10min的消防用水量。 排水系统通过设计秒流量和系统水力 计算，从而确定横支管、排出管和立管的管径和坡度，保证污废水能顺畅的排到 室外。 II Abstract Key words：Heating Supply water Drain off water Fire control Design The topic of this graduation project is the heating and t
3、he drainage system for a comprehensive officing building of Shen yang. Through the rational design the building will provide comfortable living and working environment for people. The building is six floors.The heating system contains one systems. To make the hydraulic power of systematic water cycl
4、e balance and easy to regulate, we adopted supply from the top to the bottom. Heating system design contains that first calculating heating hot lead of the building and then choosing radiaton reasonably, and do systematic water power calculating that adopted lower law to calculate.Finally, make sure
5、 the yield of circulation water and the entry pigeonhole difference of this system.Then meet the requirement for indoor temperature. The water supply system of the building inside is divided into life supply water system and fire control supply water system.The system of life water supply adopts the
6、 way of up-down set,and makes the water yield,and water pressure accord with requirements by designing the flow per second and system hydraulic calculation.And can decide the pipe diameter. This building is low structure .According to the nature of the building and fire-control norm. Assign the indoor fire hydrant rationally .The fire-fighting system adopts two entries and two water pump adapters of fire-control. water tank is set up on the top floor with water consumption of 10min.
