i南京技师学院综合教学楼空调工程设计摘要本工程为南京技师学院综合教学楼空调工程设计，该工程是集餐厅、报告厅、会议室、办公室、教室和实验室等各种功能间为一体的综合教学楼。建筑一共有十一层，其中一层的层高为4.5m，二层到十一层层高为3.6m。根据房间功能，全楼采用集中供给空调方式，其中冷热源机组采用两台直燃型溴化锂吸收式制冷机组，夏季供冷，冬季供热，还可以提供其他生活方面的供热，做到一机多用，机房设置在地下室。根据各不同功能房间，将该集中系统分为二种空调送风方式，高大空间如餐厅、报告厅等采用全空气系统，新风直接从室外引进与回风混合（一次回风）后送风；办公室，会议室等采用了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，风机盘管承担室内全部冷负荷及部分的新风湿负荷。全空气系统选用圆型散流器平射流形式，而风机盘管加独立新风系统有百叶风口侧送和散流器平送的形式。空调水系统只设有一个系统。采用闭式双管式，水平异程垂直同程式，冷水泵三台，两用一备；冷却水泵选三台，两用一备。关键词：直燃型溴化锂吸收式制冷机组；全空气系统；风机盘管加新风系统；水系统河南科技大学毕业设计iiNANJINGINSTITUTEOFCOMPREHENSIVETEACHINGBUILDINGOFTECHNICIANSAIR-CONDITIONINGENGINEERINGABSTRACTThisprojectissynthesizestheclassroombuilding’sairconditioningengineeringdesignforNanjingTechnicianInstitute,thisprojectisthecollectiondiningroom,thereporthall,theconferenceroom,theoffice,theclassroomandthelaboratoryandsoonduringeachkindoffunctionisabodycomprehensiveclassroombuilding.Theconstructionsaltogetherhave11,thefirstbuildingheightis4.5m,twoto11building’sheightsare3.6m.Accordingtotheroomfunction,theentirebuildingselectsthecentralismsuppliesairconditioningmethod,inwhichcoldheatsourceunitusestwostraighttoburnthelithiumbromideabsorptiontyperefrigerationunit,summersuppliescoldly,thewinterheats,butalsomayprovideotherlifeaspectheating,achievesonemachinemultipurpose,theengineroomestablishesinthebasement.Accordingtoeachdifferentfunctionroom,dividingintothiscentralismsystemtwoairconditioningblastway,thebigspatiallikediningroom,thereporthallandsoonusetheentireairsystem,thenewatmospheredirectlyafterreturntothewindmixfromoutdoorintroduction(onetimetoreturntowind)toblowof;Theoffice,theconferenceroomandsoonusedtheairblowerserpentinedtoaddtheindependentnewatmospheresystem,thenewatmosphereunitprocessesfromoutdoorintroductionnewatmospheretotheroomintheairenthalpyvalue,theairblowerserpentinedundertakesintheroomcompletelythecoldloadandthepartnewrheumatismload.Theentireairsystemselectsthecircletodrifttheflat-trajectoryfiremanifoldtype,buttheairblowerserpentinedaddstheindependentnewatmospheresystemtohavetheformwhichthedriedbeancurdgustyareasidedeliversanddriftsdeliversevenly.Theairconditioning河南科技大学毕业设计iiiaqueoussystemonlyisequippedwithasystem.Assoonasusescloseddoublebarrel-like,theleveldifferentregulationverticalsameformula,coldwaterpumpthree,thedualpurposeprepares;Assoonasthecoolingwaterpumpchoosesthree,thedualpurposetoprepare.KEYWORDS;Straightburnsthelithiumbromideabsorptiontyperefrigerationunit，Entireairsystem，Theairblowerserpentinedaddsthenewatmospheresystem，Aqueoussystem河南科技大学毕业设计iv目录前言..................................................................................................................1第1章原始资料...............................................................................................3§1.1室外气象资料............................................................................................3§1.2室内设计参数............................................................................................3§1.3土建资料....................................................................................................4第2章负荷计算...............................................................................................7§2.1冷负荷......................................................................................................7§2.2热负荷..................................................................................................17§2.3湿负荷计算............................................................................................18§2.4新风负荷计算........................................................................................19第3章空调系统方案的确定..........................................................................20§3.1空调系统分类...........................................................................................20§3.2空调系统方案论证....................................................................................22§3.3空调水系统...............................................................................................23第4章送风状态及送风量的确定..................................................................26§4.1全空气一次回风送风处理过程以及送风参数计算................................26§4.2风机盘管加新风的送风处理过程以及送风参数计算..............................29第5章空调设备的选择..................................................................................33§5.1风机盘管的选择.......................................................................................33§5.2新风机组的选择.......................................................................................37§5.3空调机组的选择.......................................................................................38第6章冷热源.................................................................................................41§6.1冷热源选择...............................................................................................41§6.2制冷机组的选择.......................................................................................43第7章气流组织确定及计算..........................................................................45§7.1空调房间气流组织.............................................
