XX市人民医院门诊楼空调工程设计Air-conditioningDesignforNanningMunicipalPeople'sHospitaloutpatientbuiding院系名称：XXXXX班级：建环XX学号：XXXX学生姓名：XXXXX指导教师：XXXXXXXX年XX月论文编号：（XXXXXXXXX）I摘要本设计为南宁市人民医院门诊楼中央空调工程设计。在负荷计算的基础上，通过方案比较，采用了风机盘管加独立新风和全空气两种空调系统形式。风机盘管为卧式暗装，新风不承担室内负荷；全空气系统为一次回风系统，室内送风采用散流器下送方式。新风从墙洞引入，再由各层的新风机组集中处理，然后输送到各室内。冷冻水由冷冻机房的冷水机组供应，采用了闭式同程两管制水系统。水管用泡沫橡塑保温，风管采用离心玻璃棉。工程设计中考虑了消声、减振措施。关键词：中央空调，风机盘管加新风系统，全空气系统IIAbstractThedesignofNanningPeople'sHospitaloutpatientbuildingairconditioningwasdesigned.Onthebaseofcoolingload,heatingandmoistureloadcalculation,primaryairfan-coilsystemandallairsystemareadoptedbywayoftechnicalandeconomicanalysis.Thefreshairdoesn’tundertakeindoorloadanddeliversairthroughdoubledeflectiongrilleaftermixingthereturnairinthehorizontalrecessedfancoil.Thereturnairisharnessedonetimebytheairhandlingunitintheallairsystemandthehandledairisdeliveredthroughdoubledeflectiongrillebysidewallairsupply.Thefreshairissuppliedbyholeorshaftandhandledbythefreshairhandlingunit.Thechilledwaterwhichisaclosedtwo-pipedirectreturnwatersystemissuppliedbytherefrigeratingplantroom.Thethermalinsulationmaterialofwaterpipeandairductarefoamplasticsandcentrifugalglasswoolrespectively.Measuresofnoiseelimination,damp,firepreventionandsmokeextractionisconsideredduringthedesign.KeyWords:airconditioning,primaryairfan-coilsystem,allairsystem.III目录摘要...................................................................IABSTRCT...............................................................II1工程概况...........................................................11.1原始资料...........................................................11.2计算参数...........................................................11.2.1基本气象参数...................................................11.2.2室外计算参数...................................................11.2.3室内设计参数...................................................11.3动力资料：.........................................................21.4土建资料...........................................................22负荷计算...........................................................32.1围护结构瞬变传热形成冷负荷的计算方法...............................32.1.1外墙和屋面瞬变传热引起的冷负荷.................................32.1.2内墙,楼板等室内传热维护结构形成的瞬时冷负荷....................32.1.3外玻璃窗瞬变传热引起的冷负荷...................................42.1.4透过玻璃窗的日射得热引起的冷负荷...............................42.2设备散热形成的冷负荷...............................................42.3照明散热形成的冷负荷...............................................52.4人体散热形成的冷负荷...............................................52.5新风冷负荷.........................................................53空调方案的确定....................................................83.1空调方案的分类.....................................................83.1.1按空气处理设备的集中程度分为...................................83.1.2按承担室内负荷所用的介质分为...................................83.2空调方案的比较.....................................................83.3空调系统形式确定.................................................104确定风量、送风状态点及选型计算................................124.1风机盘管加独立新风系统............................................124.1.1夏季室内新风量的确定..........................................124.1.2新风处理状态的确定，总风量及风机盘管风量的确定................134.1.3风机盘管选型..................................................164.1.4新风机组的选型................................................17IV4.2全空气系统........................................................175风管水力计算.....................................................206水管水力计算.....................................................226.1水系统形式的分类..................................................226.1.1按管道数目分..................................................226.1.2开式和闭式....................................................226.1.3按环路分......................................................226.1.4按流量来分....................................................226.2水系统形式的确定..................................................226.2.1计算基本公式：................................................236.2.2凝结水管路系统的设计..........................................236.3水力计算方法......................................................246.4风机盘管水系统设计应注意的问题....................................267冷冻站的设计.....................................................277.1制冷机组的选择....................................................277.1.1各种制冷机的优缺点比较表......................................277.1.2制冷机的性能系数（COP）.......................................287.2冷却塔的选择......................................................307.3分集水器的选择....................................................317.4膨胀水箱的选择....................................................317.5冷冻水泵的选择....................................................327.6冷却水泵的选择....................................................337.7补水泵的选择......................................................337.8其它辅助设备的选择...............................................347.8.1软水箱和软水器的选择.........................................348空调系统噪声和保温的控制........................................348.1噪声源及控制与减震设计............................................348.2管道保温处理...........................................
