医院中央空调设计论文

华北电力大学本科毕业设计（论文）I毕业设计(论文)题目郑州市某医院综合楼暖通空调系统设计院系动力工程系专业班级建环1101班学生姓名杨帆指导教师高月芬二○一五年六月华北电力大学本科毕业设计（论文）II郑州市某医院综合楼暖通空调系统设计摘要本工程为郑州市某医院空调系统设计，总建筑面积为30005m2。地上共十六层，各层层高：一层为4.5m；二至十六层为3.6m。其中有病房、手术室、诊室等。根据该工程所处的地理位置，采用冷负荷系数法详细计算逐时冷负荷，并结合工程实际情况，从高效节能，环境保护等方面加以考虑合理选择冷热源。根据房间不同功能合理采用风机盘管加独立新风系统和全空气系统，风机盘管的新风处理到室内空气焓点，新风单独送入，以达到很好的效果。对于空调的水系统和风系统全部采用假定流速法计算，采用鸿业水力计算软件进行计算。空调冷冻水系统的水管设计与采暖管路基本相同，管路要设立坡度以排除系统中空气，水系统应设定压装置，对于湿工况运行的风机盘管，设凝水排放管路。关键词：医院空调系统设计；风机盘管加独立新风系统；全空气系统；华北电力大学本科毕业设计（论文）IIITheAir-conditioningSystemDesignforaHospitalBuildinginZhengZhouAbstractThisprojectisaboutthedesignoftheair-conditioningsystemofahospitalbuildinginZhengZhoucity,thisbuildingtotalfloorisspace30000m2,thefirstfloorheightis4.5m,fromtwofloortosixteenthfloortheheightis3.6m.Thisbuildingiscomposedbysickroombedward,operatingrooms,consultingroomsandsoon.Accordingtothegeographicalpositionproject,thecoldloadcoefficientmethodisadoptedtocalculatetimingcoldload.Thewaterchillingunitforcoldsourceischosenbyconsideringengineeringpracticalsituation,energyconservation,environmentprotection.Accordingtotheroomfunction,thefreshairaddingfan-coilsystemandallairsystemisused.Inordertoformgoodperformance,theoutdoorairishandledtoenthalpypointofindoorair,andthefreshairissentintotheroomseparately.Consumedvelocitymethodisemployedinthecalculationofhydraulicandairsystem.Hongyesoftwareisadopted.Thechillwaterpipedesignoftheairconditioningissimilarwiththedesignoftheheatingwatersystem.Gradientshouldbesetuptoexcludeairfromsystem,andsetpressuredeviceforthehydraulicsystemshouldbeinstalled.Forthehumidbehavioroffan-coil,coagulatewaterdischargepipelineshouldalsobeinstalled.Keywords：Theair-conditiongingdesignforhospital;Freshairaddingfan-coilsystem;Allairsystem华北电力大学本科毕业设计（论文）目录摘要................................................................................................................................................IIAbstract.......................................................................................................................................III1工程概况......................................................................................................................................12设计依据......................................................................................................................................22.1设计任务书...............................................................................................................................22.2设计规范及标准.......................................................................................................................22.3设计计算参数...........................................................................................................................22.3.1室外气象参数........................................................................................................................22.3.2室内设计参数........................................................................................................................32.4相关参数的选取.......................................................................................................................33负荷计算......................................................................................................................................43.1冷负荷理论依据.......................................................................................................................43.1.1房间冷负荷的构成：............................................................................................................43.1.2房间湿负荷的构成：............................................................................................................43.2主要计算公式...........................................................................................................................43.2.1围护结构瞬变传热形成冷负荷的计算方法........................................................................43.2.2透过玻璃窗的日射得热引起的冷负荷................................................................................53.2.3设备散热形成的冷负荷........................................................................................................53.2.4照明散热形成的冷负荷........................................................................................................63.2.5人体散热形成的冷负荷........................................................................................................73.2.6新风冷负荷............................................................................................................................74空调系统方案的确定..................................................................................................................84.1空调系统的选取.......................................................................................................................84.1.1空调系统的划分原则............................................................................................................94.1.2方案的比较............................................................................................................................94.1.3系统的选择...................................
