中央空调系统设计方案.doc -- 6 元

毕业设计中文摘要本次设计为某疾病控制中心办公楼中央空调系统设计。该办公楼坐落于上海，为六层办公建筑，地下一层是机房和车库，一层至六层是办公用楼。通过空调方案的优缺点及适用场合的比较，结合本工程实际情况及实际设计资料（经济效益、环境效益），本次设计采用风机盘管加独立新风的半集中式空调系统，并在此基础上进行空调风、水系统及冷水机房的设计，本设计选用的冷水机组为YSBABAS05CCE型冷水机组。在设计过程中，主要做的工作有，空调系统的空调方案比较、空调系统冷负荷及湿负荷的计算、空调系统系统布置、空调设备及附件选择、空调系统水力计算、通风系统的设计和布置。最后绘制出清晰明确的工程图纸。因本人水平有限，设计中难免存在缺点和错误，恳请各位老师批评指正。关键词空调风机盘管机组负荷等毕业设计外文摘要TitleTheAirConditioningRefrigerationEngineeringDesignforACenterforDiseaseControlAbstractThisistheairconditioningrefrigerationengineeringdesignforaCenterforDiseaseControl.Thebuildingislocateystemsandchillerplantdesignonthebasisoftheairconditioning.ThedesignusestheYSBABAS05CCEtypewaterchillingunit.Inthedesignprocess,themainworkoftheairconditioningsystemhaveairconditioningschemecomparison,airconditioningcoolingloadofthesystemandmoistureloadcalculation,airconditioningsystemarrangement,airconditioningequipmentandaccessories,airconditioningandventilationsystemofthehydrauliccalculationofthedesignandlayout.Finallydrawoutaclearengineeringdrawings.Becauseofmylimited,designofexistingshortcomingsanderrorsunavoidably,yourteachercorrect.KeywordsAirconditioningFanCoilunitloadetc.本科毕业设计第I页共II页目录1引言...................................................................12设计概况...............................................................22.1概况.................................................................22.2本毕业设计课题任务的要求.............................................22.3设计原始资料.........................................................33空调系统负荷计算.......................................................33.1外墙和屋顶传热形成的逐时冷负荷.......................................33.2通过外窗得热形成的冷负荷.............................................53.3通过玻璃窗户进入室内的太阳辐射热形成的逐时冷负荷.....................63.4人体散热形成的冷负荷和散湿量.........................................83.5照明散热形成的冷负荷.................................................84划分空调系统及确定空调方案.............................................94.1空调系统的划分原则...................................................94.2空调系统方案的确定..................................................105空调系统的选择计算....................................................125.1风机盘管加新风系统选型计算..........................................125.2新风机组的选型......................................................145.3风机盘管机组的选型..................................................155.4采用吊式空调机组....................................................175.5风量计算............................................................185.6制冷机组的选型设计..................................................205.6.1制冷机台数与制冷范围..............................................205.6.2制冷机的节能性、环保性及投资运行费................................225.6.3制冷机的选型......................................................22本科毕业设计第II页共II页6空调系统的风道设计....................................................266.1确定空调房间的气流组织..............................................266.1.1气流组织介绍......................................................266.1.2送风口、回风口的选择..............................................296.2风管的布置..........................................................306.3风管的水力计算......................................................306.3.1风管的计算方法、原则..............................................316.3.2系统的管内流速....................................................316.3.3风管的计算........................................................326.3.4风道计算说明......................................................337空调水系统设计........................................................377.1选择水系统形式......................................................377.2选择管材和管道直径..................................................377.3水系统管路的布置....................................................387.4空调水量计算及泵扬程................................................387.5冷却水系统..........................................................417.6冷凝水系统..........................................................427.7水系统附件..........................................................427.8水系统的定压及其设备................................................437.9分集水器............................................................448空调系统的消声、防振与空调建筑的防火排烟等的设计......................448.1空调系统的消声......................................................448.2空调系统的隔振......................................................458.3空调系统的防火排烟..................................................458.4空调系统的爆冷、保温................................................45结论.....................................................................46致谢.....................................................................47参考文献.................................................................48
