3.2新风冷负荷计算3.2.1新风量的确定由文献[5]知在设计时，一般必须确定最小新风量，通常应满足以下三个要求：1)稀释人群本身和活动所产生的污染物，保证人群对空气品质的要求；2)补充室内燃烧所耗和局部排风量，保证房间的正压；3)新风量不小于上列两项之最大值，且计算所得的新风量的不应小于系统送风的10%。3.2.2新风负荷计算夏季，空调新风冷负荷按下式计算：（3.11）新风量按表3.1[1]取20m3/（h·人）。夏季：室内设计温度=26℃，相对湿度=60%；室外干球温度=35℃，湿球温度=28.3℃。通过焓湿图查室内外空气状态点的焓值。夏季：=92kJ/kg=58.9kJ/kg则夏季新风冷负荷为：=20×132×（92－58.9）/3600=24.3kW新风冷负荷为24.3kW，则总冷负荷为37.43＋24.3=61.73KW，平均冷负荷为83768÷394=157W/m2。热负荷通过软件计算为31482KW，平均冷负荷为31482÷394=79.9W/m2。3.3湿负荷计算商店由于人多，湿负荷主要是由人员散湿引起的，所以在商店的湿负荷计算中，只考虑了人员，忽略了其它散湿。查表3-15[1]，当室内温度设计为26℃时，成年男子每人散湿量为184g/h，由表3-14[1]查取群集系数=0.89。则精品商店不含新风的湿负荷为：=0.001×132×0.89×184=21.6kg/h=6g/s3.4其他房间负荷计算大厦地上共十层，地下室为停车场，消防水池等，只做防排烟设计，不做空调；第一、二、三层为大空间；四到十层为客房。空调负荷计算采用鸿业软件计算，负荷计算结果列入附表1。94 现将上节计算出的冷负荷进行逐时汇总，汇总列入附表2。94 第4章方案的比较确定4.1空气调节系统的分类（1）根据文献[7]可知按空气处理设备的集中程度分为：1）集中式系统：空气集中于机房内进行处理，房间内只有空气分配装置。需要占用一定的建筑面积。2）半集中式系统：对室内空气处理的设备分散在各个房间内，占用机房少，可以满足各个房间各自的温湿度控制要求，效率较高，但管理维修不方便，有可能有噪声影响。3）分散式系统：对室内进行热湿处理的设备全部分散在各房间内。不需要机房，不需要对空气进行分配的风道，不便维修管理，效率低。在此不考虑集分散式空调系统（2）按承担室内负荷所用的介质分为：1）全空气系统：根据[11]房间内的热湿负荷全部由经过处理的空气来承担，适用于面积较大人员较多的场所，新风调节方便，过渡季节可全新风运行，节约能源，占地面积大，风管占用较大空间，初投资和运行费用较高。2）全水系统：室内的热湿负荷全部靠水来承担，节省建筑空间，但室内空气品质不好。3）空气水系统：房间内的热湿负荷由经过处理的空气和水来共同承担。4.2空调系统的实现方式建筑内部设施齐全，功能复杂，且各房间的工作时间不尽相同，对于大堂吧、精品商店等面积较大，因此考虑采用集中式全空气系统，新风和回风通过设在房间的吊顶空调器集中处理后通过风道送入房间内，在空调器新风入口和回风入口处风别设电动调节阀，以便在过渡季节能够实现全新风运行，最大程度的利用自然界的能量，节约能源。对于总台办公室、美容美发室、客房等面积较小且人员活动较灵活，负荷不大，考虑采用风机盘管+独立新风系统实现，设备相对比较分散，而且风机盘管空调器使用灵活，各房间能够实现单独调节，卧式风机盘管可以吊顶安装，有效节省建筑空间。大堂面积较大，空间较高，人员停留时间相对较短，考虑采用喷口送风。餐厅面积较大，人员数量变化较大，用餐时间负荷达到最大值，非用餐时间人员很少，冷负荷和湿负荷都很大，且要保证室内空气不与其它房间掺混，考虑单独设空调系统，空气由设在餐厅附近机房的组合式空调器集中处理。94 4.3设计方案的比较确定方案一：由于本建筑有裙楼和塔楼，并且塔楼上有一块结构比较好的平台，可以考虑放置一些空调机组，现在国家对节能方面要求比较严格，考虑到空气源热泵比较灵活并且运行时比较节能，本建筑地处南京，南京风量比较充足，可以有效利用这个天然能源。方案二：整栋建筑采用一套独立的空调冷源，为水冷式冷水机组，负责整栋大楼的冷冻水供应，主机可以设计两到三台，将整栋系统分为几个集中区域，通过分水器和集水器送到各个区域。冬季供冷采用锅炉，和夏季采用同一套系统。方案一与方案二的主要区别就在于制冷主机的不同，方案一采用两套制冷主机对整栋建筑进行空气调节，上面采用空气源热泵运行时比较节能，但是由于空气源热泵单一机组的制冷量比较小，本次设计的冷量较大，故需要多台空气源热泵。综合考虑，最后确定本次空调设计的方案为方案二。4.4水冷式冷水机组对于水冷式冷水机组，根据压缩机的形式不同主要有活塞式、离心式、螺杆式1）活塞式：加工容易、造价较低；压力范围广，体积小，重量轻、噪声低、由于往复式运动的惯性力大，转速不能太高，单机容量较小，因此本机组广泛使用在柜式空调机组，房间空调器以及冷负荷在352KW以下的空调系统中。2）离心式：叶轮转速高，压缩机输气量大，故单机容量大，目前，单机空调制冷量通常在580KW以上，最大容量可达35000KW；与相同容量的活塞式相比，结构紧凑，重量轻，占地面积小，对于空调冷负荷很大的高层建筑特别适用；运转平稳，振动小，调节性能好；由于转速高，对材料的强度、加工精度和制造质量都提出了较高的要求，工况范围比较狭窄，不宜采用较高的冷凝温度和过低的蒸发温度。3）螺杆式：与活塞式相比，结构简单，零部件仅为活塞式的1/10，机组重量轻，易于维修；单机制冷量较大；能量调节时，冷量可以在15%~100%之间无级调节，当冷量在60%~100%之间调节时，功率和冷量几乎以相同比例变化；油处理设备复杂，要求使用分离效率很高的油分离器，单机容量<1160KW，适用于中、大型空调系统和空气热源热泵。本次设计中空调负荷为1209KW，选用水冷螺杆机组。94 第5章送风状态、送风量的确定及设备选型5.1送风量计算目前大型空间的空调形式主要有两种：即采用组合式空调机组的集中式全空气系统和新风机组+室内吊顶空调机组的半集中式空气—水系统。这里大空间采用一次回风全空气集中式空调系统，对于送风量的确定，按照计算的负荷及其散湿量来确定。客房等小面积房间采用半集中式的空调系统，用风机盘管加独立新风空调系统，对于送风量的确定，按照计算的负荷及其散湿量来确定。新风处理到与室内等焓状态点，直接送入室内。5.1.1大空间房间送风量和送风参数的确定以精品商店为示例计算：精品商店为一次回风的集中式空调系统，考虑温升，夏季新风和回风的处理过程如下所示：图5.1一次回风（夏季）处理过程在焓湿图上表示如下，夏季送风量和送风参数可按一下步骤确定：图5.2一次回风式夏季处理过程1、由第2章知商店冷负荷为Q=37.43KW，湿负荷为W=21.6kg/h=kg/s，因此热湿比为：==6238.3kJ/kg。根据送风温差（本设计中取送风温差7，送风温度）和94 确定，。在h-d图上分别查得点和点，查得58.8kJ/kg，46.6kJ/kg，因此，商店送风量为：kg/s=3.07kg/s=92042、新风量2640满足送风量的，所以新风量为0.88kg/s，一次回风量kg/s，3、在相应大气压力的h-d图上，过点做等含湿量线与相对湿度为90%相交与L点，即机器露点（℃,，）混合空气的比焓：空气处理机组处理空气所需冷量：=3.07（66.16-44.24）=67.2kW其他房间计算结果列于表5.1表5.1全空气系统处理结果房间名称冷负荷(KW)湿负荷(kg/h)送风量(m3/h)新风量(m3/h)空气处理机组提供的制冷量(KW)（1004）大堂67.2327.03121209.92650104.91（1005）大堂吧30.2810.45111713.4107048.75（1006）自助餐厅59.9320.71219968.24750119.08（2001）中餐厅160.0021.48023001.34750126.45（2002）中餐厅251.0124.31319763.55375129.61（3001）咖啡厅60.5127.49017825.55000125.74（3009）会议910.522.9654333.3147028.16（3010）250人宴会厅56.4424.25320217.46250140.425.1.2客房送风量和送风参数的确定经过风机盘管处理的回风与经过新风机组处理到室内等焓线的新风混合后送入室内，其处理流程如下：图5.3风机盘管加新风系统处理过程在焓湿图上表示如下：94

第6章气流组织设计6.1大空间房间气流组织示例计算散流器的布置应根据空调区的大小和室内所要求的参数，选择散流器的个数，一般按对称位置或梅花形布置，散流器送风面积的长宽比不宜大于1:1.5，散流器的中心线与墙的距离不宜小于1m。以精品商店为示例：精品商店(1007)空调系统散流器的设计计算，系统设计风量10000，房间面积394，空调机组吊顶布置，考虑到机组体积比较大，取吊顶高1.5，则净高3。根据资料8.3.2进行散流器送风的计算。（1）布置散流器。将空调区进行划分，空调区被划分成12个小区域，每个区域为一个散流器的服务区，散流器数量n=12。（2）选用方形散流器，散流器的喉部风速宜取2～5m/s，假定散流器喉部风速为3m/s，则单个散流器所需喉部面积为，计算如下：m选用喉部尺寸为W×H=250×250mm的方形散流器，则喉部实际风速为：散流器实际出口面积约为喉部面积的90%,则散流器的有效面积为：散流器出口风速为：（3）计算射程(6.1)则：m94

6.4回风气流设计回风口设计布置时注意以下几点：①采用侧送时，回风口宜设在送风口的同侧；采用孔板或散流器下送时，回风口宜设在下部；采用顶棚回风时，回风口与照明灯具宜组合成一整体；②=0.5～1℃的空调房间，回风口可布置在房间同一侧；③回风口的回风量应能调节，可采用带有对开式多叶阀的回风口，也可采用设在回风支管上的调节阀。④回风口不应设在射流区内或人员长时间停留的地点；⑤回风口的吸风速度按下表采用。表6.1回风口吸风速度回风口的位置吸风速度（m/s）房间上部4.0～5.0房间下部不靠近人经常停留的地点时3.0～4.0靠近人经常停留的地点时1.5～2.0用于走廊回风时1.0～1.5常用回风口的型式：单层百叶风口、固定百叶格栅风口、网板风口、篦孔和孔板风口等，本设计选用单层百叶回风口。精品商店回风量为7360，拟设4个回风口，根据吸风速度为3.0～4.0m/s，易知回风口尺寸不能小于。选择回风口尺寸为400mm×400mm，则实际吸风速度为3.5m/s。6.5送回风口尺寸选型汇总将大空间房间的计算结果列于表6.2中表6.2计算汇总表房间名称送风量m3/h风口数量（个/间）风口规格回风量m3/h风口数量（个/间）风口规格精品商店920412250×25065644400×400大堂2120996001855931000×500大堂吧1171312300×300106434600×400自助餐厅1744218300×300126924900×400中餐厅12300118300×3001825141000×400中餐厅21976318300×300143884900×400咖啡厅1782519300×300128254800×400250人宴会厅2021715400×400139674900×40094

比较分析，本设计采用两管制、闭式循环变流量系统，一至三层水管异程布置，四至十层采用同程布置，供回水立管采用异程布置。一至三层东侧空调水系统为分区一、西侧空调水系统为分区二、四至十层空调水系统为分区三。7.2.2水管选材空调水系统中，常用管材有焊接钢管、无缝钢管、镀锌钢管及PVC塑料管几种。空调冷、热水管道一般采用焊接钢管和无缝钢管，本设计中空调水系统水管材料采用热镀锌钢管；冷凝水管处于非满流状态，内壁接触水和空气，不应采用无防锈功能的焊接钢管；冷凝水为无压自流排放，若采用软塑料管会形成中间下垂，影响排放。因此，空调冷凝水管材应采用强度较大和不易生锈的镀锌钢管或排水PVC塑料管，管道应采用防结露措施；7.2.3供、回水管管径的确定1．空调水系统水流量空调机组的冷冻水流量G，kg/h，可按[2]中式1.5-6计算，如下：G=3600*Q/(c*Δt)（7.1）式中G——冷冻水流量，kg/h；Q——系统冷负荷总和，kW；c——水的比热容，取4.187kJ/(kg·℃)；Δt——供回水温差，取5℃。2．管径的确定（7.2）式中——水的密度，取1.2kg/m3；v——流速，m/s；按[1]中表9-6推荐值选用。从[1]中的第8条可知一般情况下，每1kW冷负荷每小时约产生0.4~0.8kg的凝结水，冷凝水盘的泄水支管沿水流方向坡度不宜小于0.01，冷凝水水平干管坡度不宜小于0.003.凝结水管的管径可按表7.4选择。表7.4冷凝水管管径选择表冷负荷kW≤4242～230231～400401～11001101～20002001～3500管径(mm)253240508010094 7.2.4水流动阻力的确定1、沿程阻力水在管道内的沿程阻力：（7.3）式中：——摩擦阻力系数，无因次量； ——直管段长度，m； ——管道内径，m；——水的密度，1000kg/m3； ——水流速，m/s；——单位长度沿程阻力，又称比摩阻(Pa/m)，冷水管路的比摩阻宜控制在100～300Pa/m.与气体管网一样，计算摩擦阻力系数的公式与流态有关。室内热水采暖管网、空调冷冻水管网和给水管网流动几乎都处于紊流过渡区，室外管网大多处于阻力平方区。因此，大多用公式（6.4）[4]和（6.5）[4]计算摩擦阻力系数：（7.4）（7.5）式中：—管内表面的当量绝对粗糙度m；闭式=0.2mm，开式=0.5mm，冷却水系统=0.5mm； Re——雷诺数，； ——运动粘度，(m2/s)。2、局部阻力：(7.6)式中：——局部阻力系数，见表8-5[1]，8-6[1]；——水流速,m/s。计算局部阻力的关键是确定局部阻力系数。3、水管总阻力水流动总阻力包括沿程阻力和局部阻力，即：（7.7）94

（8.1）式中：——水箱容积，L；——系统内单位水容量之和，L/kW；由表3-13[12]查得=31.2L/kW；——系统的总冷量或总热量，kW。本设计供热总量为700Kw。膨胀水箱的容积宜取1.5，按表8.9选择膨胀水箱。选择方形膨胀水箱，其参数如下表：表8.4膨胀水箱参数表水箱型式水箱型号L公称容积/m³有效容积/m³外形尺寸/mm长宽高方形10.50.6900900900溢流管排水管膨胀管信号管循环管水箱自重/kg50324020252008.4水泵选型计算冷源侧一次冷水泵的配置，宜与冷水机组相对应，采用“一泵对一机制”的方式。最不利环路：机组出水管--冷冻水泵—分水器—供水立管—十层最远端风机盘管—回水立管—集水器—机组回水管。最不利环路为地下一层到10层客房的环路，回水管与供水立管对称，经计算得供回水立管总阻力为95.1kPa，10层环路阻力71.7kPa，地下一层设备阻力约为110kPa最大的阻力损失为95.1+110+71.1=277kPa取安全系数1.1，则P=277×1.1=305kPa1)冷冻水泵的水量的计算考虑1.1的安全系数：2)冷冻水泵的选型：选用上海申银泵业的水泵两台单级单吸离心泵二台。表8.5水泵参数型号流量m3/h扬程m转速r/min电机功率kW必需汽蚀余量m重量kgSYW-80-200A121.637290018.54.02208.5冷却水系统设计8.5.1冷却塔的选型94 选择冷却塔时，根据当地的气象条件、进出水温度差、冷幅高（或进水温度）及处理水量，按冷却塔选用曲线或冷却塔选用水量表来选用。冷却塔安装应尽量选择通风良好和远离重要建筑物的位置，同时应尽量选择运转噪声较小的生产厂家，一般应控制环境噪声在55～60dB之内。按照冷水机组的冷却水量选择冷却水量，原则上冷却塔的水量要略大于冷水机组的冷却水量。1冷却水量计算冷却水量按下式确定：（8.2）式中：—冷却水量，kg/s；——冷却塔排走的热量，kW；取制冷机负荷的1.2倍；——水的比热容，取=4.19kJ/（kg·℃）；——冷却水的温升，已知此处为5℃。每台制冷机所需的冷却水量为：一机对一塔，采用两台冷却塔，冷却水量为228根据设计工艺条件，冷却塔放置在三楼的顶上。根据冷却水量、冷却水进水温度和出口温度，可选用由东莞明新玻璃纤维工程有限公司生产的低噪音形逆流式冷却塔MS-150，具体参数见表8.6：表8.6冷却塔主要参数型号冷却水量m3/h外型尺寸mm风机直径mm电机功率kW自重kg运行重kg水压kPa高度外径MS-1501203715364514702.210302450308.5.2冷却水泵的选型（1）水泵的扬程（8.3）式中：——冷却水系统中的沿程阻力和局部阻力；——冷凝器阻力；——冷却塔中水提升高度（从冷却塔盛水池到喷嘴的高差）；——冷却塔喷嘴喷雾压力，约等于5。（2）冷却水干管管径计算根据公式94 ，取=2m/s。则两台冷却塔共用干管管径为：所以选择管径为250mm，每台冷却塔进出水管径为150mm。（3）冷却水泵扬程冷却水泵扬程的组成1.冷却水系统水管路沿程阻力和局部阻力损失：为10mH2O；2.制冷机组冷凝器水阻力：为41500Pa；3.冷却塔喷头喷水压力：一般为2~3mH2O4.冷却塔（开式冷却塔）接水盘到喷嘴的高差：一般为2~3mH2O5.回水过滤器阻力，一般为3~5mH2O；综上所述，冷却水泵扬程约为26mH2O。（4）水泵选型取安全系数为1.1，则总阻力损失P=1.1×26=28.6mH2O。选用SYW-100-200A水泵二台，选用上海奥丰泵阀制造有限公司生产的卧式单级单级离心泵，泵的性能参数见表8.7：表8.7水泵参数型号流量m3/h扬程m转速r/min电机功率kW必需汽蚀余量m重量kgSYW-100-200A121.637290018.542158.6分水器和集水器计算分、集水器是为了连接通向各个环路的许多并联管道而设置的，在一定程度上起均压的作用，通过分集水器的断面流速为0.5-1.5m/s，当流量特别大时不超过4m/s。一般选用标准的无缝钢管。已知最大供水量为210m3/h，取通过分集水器的断面流速1m/s，供回水管的接管外径计算：根据国家建筑标准设计图集05K232选用DN300的分、集水器。分水器和集水器型号尺寸都相同，各有1个主管，管径为DN300mm；3个支管分别和1，94

第9章防排烟、通风系统设计9.1防排烟系统设计概述根据文献[8]可知防排烟是机械防烟、机械排烟和自然排烟的简称。机械防烟是利用鼓风机向防烟楼梯间及前室、消防电梯前室、合用前室加压送风，使楼梯间、前室、合用前室气压升高，以阻止烟气进入，为安全疏散创造安全环境。根据规定[2]，对于一类建筑和建筑高度超过32m的二类高层建筑的下列部位，应设置机械排烟设施。1）无直接自然通风，长度超过20m的内走道或虽有直接自然通风，但长度超过60的内走道。2）面积超过100m2，且经常有人停留或可燃物较多的地上无窗房间或设固定窗的房间3）不具备自然排烟条件或净高度超过12m的中庭。4）除利用窗井等开窗进行自然排烟的房间外，各房间总面积超过200m2或一个房间超过50m2，且经常有人停留或可燃物较多的地下室。1、防排烟系统设计原则1）走道与房间的排烟系统宜分开设置，房间的排烟系统宜按防烟分区布置。2）地下室需要排烟时，应设进风系统，进风量不宜小于排风量的50%。3）为了安全疏散，应合理布置排烟口，考虑烟气气流与人流方向相反。4）排烟风口应设有手动开启装置，或与感应器连锁的自动开启装置，或与消防中心遥控的开启装置等。排烟口平时为闭锁状态，并与风机连锁，一旦排烟口开启，排烟风机即自动开启。2、机械排烟系统的设计要点：排烟风机可采用普通的离心风机和专用的排烟轴流风机，其特性要求是保证在烟气温度的条件下，能连续工作30分钟。1）排烟口应设置在顶棚或靠近顶棚的墙面上。排烟口平时关闭，当发生火灾时，只开启火灾区的排烟口。排烟口应设置手动或自动开启装置，排烟口和排烟阀应与排烟风机连锁，任何一个排烟口或排烟阀开启时，排烟风机应能立即开启。2）机械排烟系统要控制简单、使用效果好。3）机械排烟风道必须采用非燃材料制作。风道内的风速不宜取值过大。4）安装在吊顶内的排烟管道，其隔热层应采用不燃材料制作，并应与可燃物保持不小于150mm的距离。94 9.2防火防烟分区的划分在建筑设计中，利用各种防火分隔设施，将建筑物的平面和空间分成若干个分区，成为防火分区。规定一类建筑、二类建筑和地下室，每个防火分区允许的最大建筑面积分别为1500m2、1000m2和500m2；当设置自动灭火系统时，上述面积可增加一倍。根据规定[2]，排烟设施的走道及净高不超过6m的房间，要求划分防烟分区。防烟分区可通过挡烟垂壁、隔墙或从顶棚下突出不小于0.5m的梁来划分。挡烟垂壁是用不燃材料制成，从顶棚下垂不小于500mm的固定或活动挡烟设施。活动挡烟垂壁在火灾时因感温、感烟或其他控制设备的作用，能自动下垂。规定每个防烟分区的面积的建筑面积不宜超过500m2，且不应跨越防火分区。9.3地下车库通风、防排烟系统设计9.3.1地下车库概况地下室层高4.9米，占地面积为6179，有车库、机房、高低压配电室、泵房、生活水池、相水池等功能房；停车库总面积为2691位于一个防火分区内，根据要求共分成两个防烟分区，防烟分区一：977，防烟分区二：1724，共设两个系统分别负责两个分区9.3.2排风量和排烟量的计算根据文献[1]中公式2-15：计算。式中——通风量（）；——通风房间体积（）；n——换气次数为了防止地下车库的有害气体的溢出，要求停车场内保持一定的负压。因此，地下车库的送风量要小于排风量。另外的5%到15%由门窗缝隙和车道等处渗入补充。换气次数由根据[4]第十一章典型公共建筑的通风设计可知，地下汽车库应设置独立的送、排风系统。排风量应按照稀释废气量计算，可参考换气次数估算。一般来说，排风量不少于6次/h，送风量不少于5次/h，本次设计中排风量按6次/h计算，排风和排烟共用风管。94 计算换气量时，根据[9]可知汽车库层高大于3m时按3m计算。将计算列于表9.1表9.1排风、排烟量计算分区面积（）排风量（）排烟量（）防烟分区一977防烟分区二17249.3.3风机选型根据风量来进行风机设备的选型，考虑1.1的系数，排风和排烟共用风管，配用双速电动机，平时低速排风运行，火灾时高速排烟运行（在地下室装置感烟装置与风机联动，发生火灾时发送信号到风机，风机调到高速档排烟），每个防烟分区由一个排烟排风系统负责，选用HTF（A）-Ⅱ系列轴流风机。选型结果列于表9.2表9.2风机选型及性能参数分区排风量（）排烟量（）风机型号防火分区一HTF（A）-Ⅱ-13防火分区二HTF（A）-Ⅱ-16风机性能参数见表9.3表9.3HTF-Ⅱ系列风机性能参数机号转速（r/min）风量（）风压（Pa）功率（KW）噪级dB（A）重量（kg）139607470860017/8≤9452065370710560318071696012023365230/15≤96740109686762912109129.3.4送风量计算根据文献[9]可知：在地下车库中设计了排风与排烟兼用系统，采用双速轴流排烟机，而利用车道进行自然送风。这种设计方式符合“节能”的原则，但车道送风要注意车道断面风速必然要小于0.5m/s,以保证进出车辆不受影响。对本设计的地下车库进行校核：车道横截面积:车库的送风量由计算取排风量的85%：94

第10章保温、消声与隔振10.1管道保温设计管道保温是节能的一个重要条件，其主要目的在于减少冷媒在输送过程中的无效热损失，并使冷媒维持一定的参数以满足需要。一般情况下，需要保温的管道有：冷水的供、回水管道；空调的送、回风管；可能在外表面结露的新风管及冷凝水管道。1）水管保温保温材料厚度可以根据环境温湿度、冷热介质温度和保温管的外径经计算求得。应该明确的是，除空气凝结水管外,其余计算的保温防结露厚度通常都不是最经济的厚度而只是满足了最低使用要求的厚度。根据《公共建筑节能设计标准》（GB50189-2005）附录C的表,热或冷热合用管道（管内介质温度5～60℃），经济绝热厚度要求如下：表10.1保温材料的选用厚度表材料空调水管DN≤4050≤DN＜100125≤DN＜250DN≥300玻璃棉35404550根据表中数据对应管外径便可确定其对应保温层厚度。2）风管保温（10.1）——防止结露的保温层最小厚度，mm；——保温材料导热系数，采用铝箔帖面的防潮离心玻璃棉，导热系数为0.035~0.05w/m2k，取0.05w/m2k；——外表面换热系数，一般为5.8~11.6w/m2℃，取8w/m2℃；——保温层外的空气露点温度，空调房间露点温度17.6℃，室外露点温度27.2℃；——管道内介质温度，对于风管取露点送风点温度16.9；——室外空气温度，需保温的管道不在室内时取室外最热月历年平均温度31.4℃。本设计取20mm，外缠玻璃布保护层，再刷两道防火涂料。94 10.2消声与隔声设计空调系统的消声和减振是空调设计中的重要一环，它对于减小噪声和振动，提高人们大额舒适感和工作效率，延长建筑物的使用年限有着极其重要的意义。噪声的控制方法主要有隔声、吸声和消声三种。本空调系统的噪声主要是风道系统中气流噪声和空调设备产生的噪声。一般而言室外噪声源是经过维护结构穿透进入的，建筑物内部的噪声、振动源主要是由于空调、给排水、电气设备后产生的，其中以空调制冷设备产生的噪声影响最大。包括其中的冷却塔、空调制冷机组、通风机、风管、风阀等产生的噪声。其中主要的噪声源是风机。风机噪声是由于叶片驱动空气产生的紊流引起的宽频带气流噪声以及相应的旋转噪声所组成，后者由转数和叶片数确定其噪声频率。为了消除或减弱各种噪声源传入室内需采取以下措施：（1）选用低噪声型风机，风机进出口均设软接，水泵与水管等用橡胶管或球形橡胶接头等柔性连接。（2）风机盘管、空调处理机组均吊装于吊顶内，可适当降低噪声；另外风机盘管带回风箱亦可降低噪声，空调机组和新风机组设置消声静压箱；（3）管道穿过空调房间的围护结构其孔洞四周的缝隙必须用弹性材料填充实心密实。10.3减振设计空调系统中的通风机、水泵、制冷压缩机是产生振动的振源。这些振动会影响人的身体健康，有时还会危及支撑结构的安全。因此，需要对震源采取隔振措施。1）水泵和水冷螺杆式冷水机组固定在隔振基座上。隔振基座用钢筋混凝土板加工而成；2）水泵的进、出口采用橡胶柔性接头同水管连接；3）空调机组和新风机组风机进出口与风管间的软管采用帆布材料制作，水管、风管敷设时，在管道支架、吊卡、穿墙处作隔振处理。94 结论这次设计的是南京市一栋大厦的中央空调系统设计，主要任务是完成整栋大楼冷负荷的计算；各楼层水系统和风系统的设计计算；系统冷冻站的设计。在设计中考虑到了各房间的不同特点对应不同的空调形式，针对不同的房间分别采用了喷口送风和侧送风、散流器平送风等不同方式。对系统消声减振做了简单的阐述。但是在设计过程中，明显觉得自己知识体系的欠缺，浪费了不少时间，设计也改了多次，像在选冷水机组的时候，刚开始是把每个房间的最大负荷进行叠加，后来经过老师指导，应该以整栋楼出现的最大冷负荷作为选型时的负荷，因为每个房间出现最大值的时间不都是一致的，这样算出来的负荷会明显变大，造成能源的浪费。总而言之，这次设计使我的设计能力有了提高，在以后工作中，我会不断努力学习，多看规范，尽自己最大的努力提高设计质量。94
