1北京理工大学珠海学院2016届本科生毕业设计长沙某医院洁净空调系统设计长沙某医院洁净空调系统设计摘要本设计为湖南省长沙市某医院大楼洁净空调系统设计，本着为医院提供经济适用的方案、为医疗提供洁净的操作环境为原则。该医院共两层，层高3.2m，面积4322㎡，拟洁净区域采用分散式全空气系统，非洁净区域采用风机盘管加独立新风系统，每一个末端装置都设置调节系统和电源开关，此方案可以独立独自调节与控制各房间的温度、湿度，占用面积少，亦可实现集中供冷。设计内容：查找建筑物平面建筑图，搜集当地气象相关资料；用天正暖通把建筑信息及房间信息输入，对每间房间的冷负荷和湿负荷进行计算；接下来是确定适合本工程的系统方案并规划好空调系统分区，计算好之后根据计算结果选择末端装置与空调机组，接下来选择冷冻水系统，布置空调水路并进行水管水力计算，更新水管管径，控制并联管道不平衡率，随后选择气流组织，布置风管并进行风管水力计算，更新风管管径，最后选择机房设备并进行布置。本设计经过认真严谨的计算、校核及设计，达到了空调设计的标准。关键词：洁净空调；全空气系统系统；风机盘管。2北京理工大学珠海学院2016届本科生毕业设计DesignofcleanairconditioningsysteminahospitalinChangshaAbstractThisdesignisacleanair-conditioningsystemforahospitalbuildinginChangsha,HunanProvince.Itisbasedontheprincipleofprovidingeconomicalandapplicableschemeforhospitalandcleanoperatingenvironmentformedicaltreatment.Thehospitalhastwofloors,aheightof3.2m,anareaof4322㎡,theproposedcleanareausesadecentralizedfullairsystem,theuncleanareausesafancoilplusanindependentfreshairsystem,eachenddeviceisequippedwitharegulatingsystemandpowerswitch,thisschemecanindependentlyadjustandcontrolthetemperatureandhumidityofeachroom,occupylessarea,canalsoachievecentralizedcooling.DesignContent:Findthebuildingplan,collectthelocalmeteorologicaldata;inputthebuildinginformationandroominformationwithTianzhengHVAC,calculatethecoolingloadandwetloadofeachroom;Nextistodeterminethesystemplansuitableforthisprojectandplantheairconditioningsystempartition,afterthecalculation,selecttheterminaldeviceandairconditioningunitaccordingtothecalculationresult,thenselectthechilledwatersystem,arrangetheairconditioningwaterwayandcarryonthewaterpipehydrauliccalculation,updatethepipediameter,controltheimbalancerateofparallelpipe,thenselecttheairfloworganization,arrangetheairductandcarryontheairducthydrauliccalculation,updatetheairductdiameter,finallyselectthemachineroomequipmentandcarryontheairconditioningunit,thenselectthechilledwatersystem,arrangetheairconditioningwaterwayandcarryonthewaterhydrauliccalculation,thenselecttheairfloworganization,arrangetheairductandcarryontheairducthydrauliccalculation,updatetheairductdiameter,finallyselectthemachineroomequipmentandcarryontheairconditioningunit.Layout.Thedesignthroughcarefulandrigorouscalculation,checkanddesign,tomeettheairconditioningdesignstandards.3北京理工大学珠海学院2016届本科生毕业设计Keywords:Cleanairconditioning;allairsystem;fancoil.目录1建筑资料...........................................................................................................11.1气象参数............................................................................................................11.2建筑概况及工况设定........................................................................................12空调系统的负荷计算.......................................................................................32.1冷负荷计算.........................................................
