市政与环境工程系MUNICIPALANDENVIRONMENTALENGINEERINGDEPARTMENT-I-前言随着社会的不断进步，科学技术的发展，以及人们生活水平的不断提高，空调技术在促进国民经济和科学技术的发展、提高人们的物质文化生活水平等方面都起着重要的作用。空气调节是为满足生活、生产要求,改善劳动卫生条件,用人工的方法使室内空气温度、湿度、洁净度和气流速度达到一定要求的技术。本设计为吉林省长春市民航宾馆舒适性空调设计，根据建筑本身的要求及空调各系统的特点，本设计采用风机盘管加独立新风系统。风机盘管加新风系统各个房间可独立调节，相互影响不是很大，是目前广泛采用的方式。房间噪声太大，舒适性就会下降，为了降低噪声，新风机组处设置静压箱。本设计制冷设备选用风冷螺杆式冷水机组。风冷机组在装配性能上除具备水冷式螺杆机组系列的一般特征外，其最大的优点是不需要水冷却系统，只要是通风良好的地方便可以使用。风冷机组不需要配备冷却水泵、冷却塔等辅助设备，可大量节省材料及工程安装费用，甚至不需要设置机房。可广泛用于宾馆、酒楼、商场、学校、医院、办公室等各类工业与民用建筑环境空调系统。展望21世纪空调行业的发展，必将是走向一个稳步的可持续发展的道路。可持续性发展意味着资源持续利用、生态环境得到保护和社会均衡发展。其中能源是一项主要的资源，全国电力资源很紧缺，降低空调系统中的电能消耗是本设计中优先考虑的问题，在选择设备时，在满足各个指标的情况下，选择了功率相对较小的设备，以使电能消耗降低到相对较低状态。本设计主要目的是运用学过的基础理论和专业知识及实习中接触到的实例并结合相关的数据，将理论和实际有机结合起来。市政与环境工程系MUNICIPALANDENVIRONMENTALENGINEERINGDEPARTMENT-II-PrefaceWiththeconstantprogressofthesociety,thedevelopmentofscienceandtechnology,andconstantlyimprovethelivingstandardsofpeople,airconditioningtechnologyinpromotingthenationaleconomyandthedevelopmentofscienceandtechnology,improvepeople'smaterialandculturallifelevelplaysanimportantrolein.Airconditioningisthelife,tomeetproductionrequirements,improvingoccupationalhealthconditions,theuseofartificialmethodsofindoorairtemperature,humidity,cleanlinessandairflowvelocityreachesacertaintechnicalrequirements.ThedesignfortheJilinProvince,ChangchunCitycivilaviationguesthousecomfortableair-conditioningsystemdesign,accordingtothebuildingitselfandthecharacteristicsofairconditioningsystem,thisdesignadoptfan-coilunitplusfreshairsystem.Fancoilplusfreshairsystemineachroomcanbeadjustedindependentlyofeachother,theimpactisnotgreat,iscurrentlywidelyusedways.Theroomistoonoisy,comfortwillfall,inordertoreducenoise,airsupplyunitisarrangedatthestaticpressurebox.Thedesignofrefrigerationequipmentselectionforaircooledscrewchiller.Aircooledunitsintheassemblyperformancewiththeexceptionofwater-cooledscrewchillerseriesofgeneralcharacteristics,itsbiggestadvantageisneednotwatercoolingsystem,aslongasitistheplacewithgoodventilationcanuse.Aircooledunitsdonotneedtobeequippedwithcoolingwaterpump,coolingtowerandotherauxiliaryequipment,cansavealotofmaterialsandinstallationcosts,evendoesnotneedtosetuptheroom.Canbewidelyusedinhotels,restaurants,shoppingmalls,schools,hospitals,市政与环境工程系MUNICIPALANDENVIRONMENTALENGINEERINGDEPARTMENT-III-officeandothertypesofindustrialandcivilconstructionenvironmentofairconditioningsystem.Lookintotwenty-firstCenturythedevelopmentofair-conditioningindustry,tobeasteadypathofsustainabledevelopment.Sustainabledevelopmentmeansthatthesustainableutilizationofnaturalresources,ecologicalenvironmentprotectionandsocialdevelopment.Whichenergyisoneofthemainresources,nationalelectricpowerresourceisscarce,reduceairconditioningsysteminelectricityconsumptionisthedesignofpriority,whenselectingequipment,tomeetthevariousindicatorsofthesituation,choosepowerofarelativelysmallequipment,inordertomaketheelectricpowerconsumptionisreducedtoarelativelylowstate.Themainpurposeofthisdesignistheuseoflearnedbasictheoryandprofessionalknowledgeandpracticeintocontactwiththeexampleandcombiningwiththerelateddata,integratetheoryandpractice.市政与环境工程系MUNICIPALANDENVIRONMENTALENGINEERINGDEPARTMENT-IV-目录前言..............................................................IPreface..........................................................II第1章原始资料...................................................11.1工程名称及概况...............................................................................................11.2气象资料...........................................................................................................11.3动力资料...........................................................................................................21.4土建资料...........................................................................................................21.5其它参数...........................................................................................................3第2章负荷计算...................................................42.1热负荷计算.......................................................................................................42.1.1空调房间冬季热负荷计算......................................................................42.2冷负荷计算.......................................................................................................4房间冷负荷的构成..............................................................................................42.2.1外围护结构瞬变传热形成的冷负荷.........................................................42.2.2透过玻璃窗的日射得热引起的冷负荷.....................................................62.2.3人体散热形成冷负荷和散湿量.................................................................62.2.4照明散热形成的冷负荷.............................................................................82.2.5湿符合的计算...........................................................................................14第三章送风量及送风状确定态....................................223.1气流组织设计.................................................................................................223.1.1散流器下送气流组织设计.........
