医院门诊楼空调系统设计(毕业设计)

河南科技大学毕业设计I天津肿瘤医院门诊楼空调系统设计摘要本设计为天津肿瘤医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。对于候诊大厅等少数房间采用了全空气一次回风系统。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，全空气系统，风机盘管加新风系统，性能比较河南科技大学毕业设计IITHEAIR-CONDITIONINGENGINEERINGDESIGNOFTHETUMORHOSPITALOUT-PATIENTFLOORINTIANJINABSTRACTThisair-conditioningsystemsdesignfortheTianjinTumorHospitalout-patientfloordesignittobeareasonablecentralair-conditioningsystemforindoorstaffprovideacomfortableworkingenvironment.Fan-coilsystemismainlyusedair-conditionedroomsbearthecoolingloadandtheheatload,theceilingofeachroomplacementwithin1-2fan-coils.Thenewwindoffreshairthroughindependentchannelsintothefirstfan-coil,andthenmixedtogetherwithreturnairintotheroom.Newwindgeneratingunitsinstalledonceiling,eachfloortoinstallanewairunitoftheburdenofallair-conditionedroomsinthenewwindload.Theair-conditioningsystemhastheadvantageofoccupyinglessfloorspace,coolingandheatingcanbeconcentratedatthesametime,theterminaldeviceandaseparateregulatoryfunctionswitch,theroomtemperaturealonecanregulateandcontrol,andpreventcross-infectionoftheair.Thewaitinghallandafewroomsusedareturnairtotheentireairsystem.Air-conditioningsystemusesclosed-watersystems,notbecauseitapartfrompollution,saveinitialinvestment,butalsohasgreatenergy-savingeffect.Thedesignelementsinclude:hotandcoldair-conditioningloadcalculation;air-conditioningsystemandthedeterminationofproof;airsupplyandairsupplyparametersofthedetermination;selectionofair-handlingequipment;coldandheatsourceofchoiceandselectionofequipment;airflowcalculated;hydrauliccalculation;otherequipmentofchoice;thermalinsulationandanti-corrosionandvibrationandnoisereduction,andothercontent.河南科技大学毕业设计IIIKEYWORDS:air-conditioningsystems,theentireairsystem,fancoilandanewairsystem,performancecomparison.河南科技大学毕业设计IV目录前言..................................................1第一章原始资料........................................2§1.1工程概况......................................2§1.2气象资料......................................2§1.3土建资料......................................2§1.3.1外墙、内墙选型..........................2§1.3.2屋面选型................................3§1.3.3楼板选型................................3§1.3.4外围护结构校核..........................3§1.3.5其他相关资料............................4第二章负荷计算........................................5§2.1冷负荷的计算..................................5§2.1.1冷负荷的计算方法.........................5§2.1.2空调冷负荷计算..........................5§2.2湿负荷计算....................................7§2.3热负荷计算....................................8§2.3.1建筑围护结构的基本传热量................8§2.3.2附加耗热量..............................8§2.4各房间负荷的计算..............................9§2.4.1101房间冷负荷计算.......................9§2.4.2101房间热负荷的计算....................12§2.4.3101房间湿负荷的计算....................13第三章空调系统的确定及论证...........................14§3.1空调系统的确定...............................14§3.1.1空调系统的分类.........................14§3.1.2空调水系统的分类.......................14§3.2本次设计的方案...............................16§3.2.1风机盘管加新风系统.....................16§3.2.2全空气一次回风空调系统.................16河南科技大学毕业设计V§3.3方案比较论证.................................16§3.3.1一次回风、二次回风空调系统比较.........16§3.3.2定风量与变风量系统的比较...............17§3.3.3风机盘管加新风与空气-水诱导器系统的比较17§3.3.4风机盘管与新风连接方式的比较...........17§3.4结论.........................................18第四章送风状态参数及送风量的确定.....................19§4.1新风量规定...................................19§4.2风机盘管系统风量的计算.......................19§4.2.1风机盘管的夏季处理过程..................19§4.2.2风机盘管的冬季处理过程。................20§4.3全空气一次回风空调系统风量的计算.............21§4.3.1全空气一次回风系统的夏季处理过程.......21§4.3.2全空气一次回风系统的冬季处理过程.......22第五章空气处理设备的选型.............................24§5.1风机盘管的选型...............................24§5.2新风机组的选型...............................27§5.3全空气处理机组的选型.........................28第六章冷热源的选择及设备选型.........................30§6.1冷热源的选择.................................30§6.1.1冷源...................................30§6.1.2热源...................................31§6.2机组选型.....................................31§6.2.1冷水机组...............................31§6.2.2换热器.................................32第七章气流组织计算...................................34§7.1气流组织方案论证.............................34§7.1.1风口形式的确定.........................34§7.1.2气流组织形式的确定.....................34§7.2气流组织计算.................................35§7.2.1风机盘管侧送风.........................35河南科技大学毕业设计VI§7.2.2全空气系统散流器平送气流组织计算.......36§7.2.3回风口的选择计算.......................37第八章管道布置及水力计算.............................39§8.1空调水系统水力计算...........................39§8.1.1水管管径的确定.........................39§8.1.2阻力的确定.............................39§8.1.3计算步骤如下...........................40§8.1.4水系统的水力计算.......................41§8.2风管的水力计算...............................46§8.2.1风管系统...............................46§8.2.2风管水利计算的内容.................
