摘要本设计为武汉某院门诊楼空调系统设计，拟为之设计合理的中央空调系统，为室内人员提供舒适的工作环境。系统主要采用风机盘管承担空调房间的冷负荷与热负荷，每个房间的吊顶内安置一到二个风机盘管。新风则由新风机组处理后通过独立的新风管道先送入风机盘管，再与回风混合一起送入房间。新风机组吊顶安装，每一层楼安装一台新风机组负担该层所有空调房间的新风负荷。该空调系统的优点是占用建筑面积少，可集中供冷和供热；同时各末端装置有独立的开关和调节功能，各房间的温度可独自调节与控制，并且防止了空气的交叉感染。空调水系统采用闭式系统,因为它除了不易污染,节省初投资外,还具有很大的节能效果。本次设计的建筑对象位于武汉市,该建筑的楼层结构为地上八层，总建筑面积约为6500m2，其中设计空调面积4500m2，空调总冷负荷为660kw，单位面积冷指标为146W，单位面积热指标为110W。本设计内容包括：空调冷热负荷计算；空调系统的确定及论证；送风状态参数及送风量的确定；空气处理设备的选型；冷热源的选择及设备选型；气流组织计算；水力计算；其他设备的选择；保温与防腐以及减振和消声等内容。关键字：空调系统；风机盘管加新风系统；性能比较；末端设备ABSTRACTThisair-conditioningsystemsdesignfortheWuhanTumorHospitalout-patientfloordesignittobeareasonablecentralair-conditioningsystemforindoorstaffprovideacomfortableworkingenvironment.Fan-coilsystemismainlyusedair-conditionedroomsbearthecoolingloadandtheheatload,theceilingofeachroomplacementwithin1-2fan-coils.Thenewwindoffreshairthroughindependentchannelsintothefirstfan-coil,andthenmixedtogetherwithreturnairintotheroom.Newwindgeneratingunitsinstalledonceiling,eachfloortoinstallanewairunitoftheburdenofallair-conditionedroomsinthenewwindload.Theair-conditioningsystemhastheadvantageofoccupyinglessfloorspace,coolingandheatingcanbeconcentratedatthesametime,theterminaldeviceandaseparateregulatoryfunctionswitch,theroomtemperaturealonecanregulateandcontrol,andpreventcross-infectionoftheair.Air-conditioningsystemusesclosed-watersystems,notbecauseitapartfrompollution,saveinitialinvestment,butalsohasgreatenergy-savingeffect.ThedesignofthebuildingobjectislocatedinWuhanCity,basementflooreightlayerswithatotalconstructionareaofabout6500,thetotalair-conditioningcoolingloadforthe660KW,perunitareaofcoldindicators146W,unitareaheatindexof110W.Thedesignelementsinclude:hotandcoldair-conditioningloadcalculation;air-conditioningsystemandthedeterminationofproof;airsupplyandairsupplyparametersofthedetermination;selectionofair-handlingequipment;coldandheatsourceofchoiceandselectionofequipment;airflowcalculated;hydrauliccalculation;otherequipmentofchoice;thermalinsulationand
