暖通空调设计_毕业设计说明书

车辆与动力工程学院毕业设计说明书I摘要本设计为哈尔滨望江集团办公楼空调系统工程设计。哈尔滨望江集团办公楼属中小型办公建筑，本建筑总建筑面积4138m2，空调面积2833m2。地下一层，地上八层，建筑高度33.9m。全楼冷负荷为191千瓦，全楼采用水冷机组进行集中供给空调方式。此设计中的建筑主要房间为办公室，大多面积较小，且各房间互不连通，应使所选空调系统能够实现对各个房间的独立控制，综合考虑各方面因素，确定选用风机盘管加新风系统。在房间内布置吊顶的风机盘管，采用暗装的形式。将该集中系统设为风机盘管加独立新风系统，新风机组从室外引入新风处理到室内空气焓值，不承担室内负荷。风机盘管承担室内全部冷负荷及部分的新风湿负荷。风机盘管加独立新风系统由百叶风口下送和侧送。水系统采用闭式双管同程式，冷水泵三台，两用一备；冷却水泵选三台，两用一备。在冷负荷计算的基础上完成主机和风机盘管的选型，并通过风量、水量的计算确定风管路和水管路的规格，并校核最不利环路的阻力和压头用以确定新风机和水泵。依据相关的空调设计手册所提供的参数，进一步完成新风机组、水泵、热水机组等的选型，从而将其反应在图纸上，最终完成整个空调系统设计。关键词：风机盘管加独立新风系统；负荷；管路设计；制冷机组：冷水机组车辆与动力工程学院毕业设计说明书IIAbstractThedesignfortheHarbinWangjiangDesignGroupofficebuildingairconditioningsystem.HarbinWangjiangGroupisasmallandmedium-sizedofficebuildingofficebuildings,thetotalfloorareaofbuildingis4138m2,air-conditionedareais2833m2.Thereareeightfloorofthebuilding,buildingheightis33.9m.Coolingloadfortheentirefloor,191kilowatts,thewholefloorusingCentralCoolingChillerstofocusontheway.Thisdesignofthemainroomofthebuildingforoffice,mostofthemisverysmall,andtheroomsarenotconnected,theselectedair-conditioningsystemshouldbeabletoachieveindependentcontrolofeachroom,consideringthevariousfactorstodeterminetheselectionoffan-coilplusfreshairsystem.Arrangementintheroomceilingfancoilunits,usingthedarkformofequipment.Setthefocusonfan-coilsystem,plusanindependentairsystem,freshairfromtheoutdoorunittodealwiththeintroductionofanewwindtotheindoorairenthalpyvalue,donotbeartheloadofindoor.Allbeartheindoorfan-coilcoolingloadandpartofitsnewrheumatoidload.Fan-coilplusanindependentairsystemsentbytheVenetianandtheundersideairdelivery.Closedwatersystemwithadual-trackprogram,threecold-waterpump,dual-useaprepared;coolingpumpsthreeelections,onepreparedbydual-use.Inthecoolingloadcalculationbasedonthecompletionoftheselectionofhostandfancoilunits,andairvolume,thecalculationofwater,thewindpipeandwaterpipestodeterminethespecificationsoftheroadandchecktheresistancetothemostdisadvantagedandthelooptodeterminethepressureheadnewfansandpumps.Basedontherelevantmanualsprovidedbyair-conditioningdesignparameters,andfurthercompletionofthenewairunits,waterpumps,hotwaterunits,suchastheselection,whichwillbereflectedintheirdrawings,thefinaldesignoftheentireair-conditioningsystemKeywords:PAU+FCUsystems;load;pipelinedesign;refrigerationmachine；Chillers车辆与动力工程学院毕业设计说明书III目录摘要...................................................................IAbstract................................................................II目录..................................................................III1设计依据..............................................................11.1设计任务书.......................................................11.2建筑平面图和剖面图...............................................11.3国家主要规范和行业标准：.........................................11.4哈尔滨市设计计算参数：...........................................11.4.1室外计算参数...............................................11.4.2室内计算参数...............................................11.4.3其他设计参数...............................................11.5建筑围护结构的热工性能...........................................21.5.1外墙.......................................................21.5.2内墙.......................................................31.5.3屋面.......................................................41.5.4外门.......................................................41.5.5外窗.......................................................41.6设计范围：.......................................................51.7设计原则：.......................................................52负荷计算..............................................................62.1空调冷负荷的计算.................................................62.1.1外墙冷负荷与屋面冷负荷：....................................62.1.2玻璃窗瞬变传热引起的冷负荷：...............................62.1.3透过玻璃窗进入的日射得热引起的冷负荷：.....................72.1.4照明散热引起的冷负荷：.....................................72.1.5人员散热引起的冷负荷：.....................................72.2调热负荷的计算：................................................122.3空调湿负荷的计算：..............................................143系统选择.............................................................153.1冷热源选择：....................................................153.1.1选择冷热源系统的基本原则：................................153.1.2冷热源系统方案的比较......................................153.1.3冷热源系统方案的确定......................................163.2空调系统的选择..................................................163.2.1空调系统设计的基本原则....................................163.2.2空调系统方案的比较........................................173.3空调系统方案的确定：............................................184新风负荷的计算.......................................................194.1新风量的确定....................................................19车辆与动力工程学院毕业设计说明书IV4.2空调新风冷负荷的计算：..........................................195空气处理设备的选择...................................................215.1风机盘管的选择：................................................215.1.1风机盘管处理过程..........................................215.1.2风机盘管的选取............................................225.1.3风机盘管的布置................
