某办公综合楼暖通空调设计

XXXX大学毕业设计(论文)专业建筑环境与设备工程专业班级10建环2班学生姓名XXX学号1020302021课题南京市某办公综合楼暖通空调设计指导教师2014年6月12日摘要本设计为南京市某办公综合楼空调设计，建筑地下一层，地上十二层。地下一层为设备房和停车库，地上一层为营业大厅，二层为会议室，三层为餐厅，四至十二层为办公场所。根据建筑功能特点，选取全空气系统和风机盘管+独立新风系统的空调方式，对于会议室等大空间采用全空气系统，接待，办公等较小的空间就用风机盘管+独立新风系统，独立新风+风机盘管的空调方式是由风机盘管承担室内冷负荷，而新风负荷由各层新风机组来承担，新风通过新风机组处理到与室内等焓值的状态，直接送入房间。公共卫生间设置排气系统，冷水机组布置在地下一层机房内。针对地下一层的实际使用情况，系统设计了排风方案，采用机械进风和机械排风系统。关键词：风机盘管加新风系统空调水系统排风排烟系统AbstractThedesignofairconditioningdesignandconstructionofaNanjingofficialbuildingis12layers,includingthebasementroomsfortheequipmentandstoragerooms.Thefirstflooris,numbertwoismeetingroom，numberthreeisdiningroom，Numberfourtotwelveforthe0ffices。Accordingtoconstructionfeatures,toselecttheentireairsystemandairsystemwithfancoilandindependent,andtoselectafullyintegratedairsystemforthebigmeetingroom,officeandothersmallspaceonthediskwithfanPipe+independentairsystemistheproperselection.Independentfreshairandfancoilfancoilair-conditioningmodeisbornebytheindoorcoolingload,andthenewwindloadfromthefloorsbearsthenewairunits.Thenewairhandlingunitthroughthefreshairmakesittotheenthalpyandinteriorspaceandotherstate,whichisdirectlyintotheroom.Thepublicbathroomaresettingexhaustsystem.Waterchillersaresetinthebasementoftheengineroomlayout.Forthepracticaluseofthebasement,theventilationsystemdesignprogramsareusedwiththemechanicalventilationandmechanicalventilationsystem.KeyWords：Airdistributionprimaryairfan-coilsystemandindependentAirconditionwatersystemLineupthebreezerowsmokesystem目录第1章工程概况...................................................................................................................11.1工程名称.....................................................11.2地理位置.....................................................11.3气象参数.....................................................11.3.1夏季参数...............................................11.3.2冬季参数...............................................11.4建筑概况.....................................................1第2章设计依据及基础数据........................................................................................22．1设计依据....................................................22．2基础数据....................................................22.2.1土建资料...............................................22.2.2室内设计标准...........................................32.2.3建筑热工数据...........................................52.2.4动力及冷热源条件.......................................5第3章负荷计算...................................................................................................................53.1空调冷负荷...................................................53.1.1空调冷负荷计算方法.....................................63.1.2空调湿负荷............................................103.1.3空调冷负荷汇总........................................123.2空调热负荷..................................................123.2.1空调热负荷计算方法....................................123.2.2空调热负荷汇总........................................14第4章冷热源工艺设计.................................................................................................154.1方案拟订...................................................154.1.1备选方案..............................................154.1.2机组初选型............................................164.2方案比较....................................................164.2.1技术性比较............................................174.3确定方案...................................................174.4冷热源设备选型..............................................184.4.1冷水机组选型计算......................................184.5水泵选型....................................................184.5.1冷冻水泵选型..........................................194.5.3补水泵选型............................................194.5.4热水循环泵............................................194.6冷却塔选型..................................................194.7其他设备选型................................................204.7.1定压、补水装置........................................204.7.3水处理装置............................................21第5章空调系统设计...................................................................................................215.1系统方案....................................................225.1.1空调方式..............................................235.2空气处理及设备选型.........................................245.2.2风机盘管加新风系统....................................255.3空调风系统设计..............................................255.3.1多联机加新风系统......................................255.3.2风机盘管加新风系统....................................265.4空调水系统设计..............................................285.4.1水系统形式及布置......................................285.4.2空调水系统............................................295.4.3空调冷凝水系统........................................305.4.4空调水系统水力计算....................................305.4.5空调冷凝水系统的计算..................................305.5气流组织....................................................315.5.1气流组织的形式........................................325.5.2气流组织计算..........................................335.6消声减震....................................................375.6.1消声.
