北京市住宅采暖及小区换热站设计

摘要随着社会经济的不断发展，居民的生活水平质量也有所提高，人们不再单纯地追求住宅的实用性和安全性，还对住宅的美观性和舒适性有了更高的要求，所以居民越来越重视住宅的供暖设计问题。本设计的题目是北京市住宅采暖及小区换热站设计，本次设计建筑共11层，建筑高度为33米，采用的是地板辐射采暖的采暖方式。我所设计的目标是住宅楼，采用分户计量热水供暖系统，供回水温度为55/45°C。水-水热交换系统共分2个系统，地板高区采暖系统：供热面积9万m:地板低区采暖系统：供热面积10万m。地板供暖是以温度不高于60℃的热水作为热源，在埋置于地板下的盘管系统内循环流动，加热整个地板，通过地面均匀地向室内辐射散热的一种供暖方式。它对地面装饰材料有透热方面的要求。通过设计过程熟悉供暖设计的程序、内容和基本原则，学习设计的方法步骤，进一步提高运算、制图和使用资料的能力，巩固所学的知识，培养这些知识解决设计问题的能力。关键词：地板采暖：小区换热站：设备选型ABSTRACTWith the continuous development of the social economy,the quality of living of residents hasalso improved,people no longer simply pursue the practicality and safety of the residence,but alsohave higher requirements for the beauty and comfort of the residence,so residents pay more andmore attention to the heating design of the residence.The title of this design is the design of Beijing residential heating and residential heatexchange station,this building has a total of 11 floors,the building height is 33 meters,and theheating method of floor radiant heating is adopted.The target of my design is a residential building,with a metered hot water heating system with a supply and return water temperature of 55/45C.Water-water heat exchange system is divided into 2 systems,floor high area heating system:heatingarea of 90,000 square meters;Floor low area heating system:heating area of 100,000 square meters.Floor heating is a heating method that uses hot water with a temperature of not higher than 60 C asa heat source,circulates in the coil system buried under the floor,heats the entire floor,and evenlyradiates heat to the room through the ground.It has heat permeable requirements for floordecoration materials.Through the design process,be familiar with the procedures,contents andbasic principles of heating design,learn the method steps of design,further improve the ability ofcalculation,drawing and use data,consolidate the knowledge learned,and cultivate the ability ofthese knowledge to solve design problems.Keywords:floor heating;Community heat exchange station;Equipment selection目录第1章设计资料...…1.1地暖设计题目....1.2设计任务和目的....11.3设计原始资料....…11.3.1建筑概况...11.3.2气象资料.......11.3.3围护结构资料......…。.................2第2章住宅供暖热负荷计算....32.1室内设计温度的确定....32.2地板供暖热负荷计算....·…42.2.1围护结构的耗热量..…42.2.2围护结构附加修正耗热量...............52.2.4冷风渗透耗热量：6第3章热水供暖系统方案确定及计算123.1地暖盘管设计方式...............123.1.1加热管的布置.....123.1.2分集水器.......123.2户内采暖管道布置方式.....…123.3盘管材质确定...….133.4盘管间距的确定........3.5地面表面温度校核........第4章地面辐射供暖水力计算..........164.1低温热水系统的加热管及分集水器系统设计.............164.2低温热水系统的加热管水力计算....…164.21确定户内管径（供回水干管、地暖盘管）..…164.2.2确定管径（供回水立管）....184.2.3户内环路阻力计算.....194.3并联环路的立管不平衡率计算...20第5章换热站的选型及计算....215.1换热站基本信息....……….215.2循环水泵的选择......215.2.1循环水泵的选择原则.....215.2.2循环水泵参数的确定225.3补水泵选型及计算235.3.1选取原则..235.3.2补水泵的计算...245.4软化水箱的选择......245.5换热器的选型及计算265.5.1换热器基本信息.265.5.2换热器的选型及计算265.5.3设计选用要点285.6换热站内管径的计算...285.6.1换热站管道管径计算28参考文献…30致谢..31附录1部分围护结构基本耗热量计算表32附录2部分冷风渗透耗热量计算表...36第1章设计资料1.1地暖设计题目本设计的题目是北京市住宅采暖及小区换热站设计，本建筑共11层，建筑高度为33米，采用的是地板辐射采暖的采暖方式。我所设计的目标是住宅楼，采用分户计量热水供暖系统，供回水温度为55/4
