贵州大学本科毕业论文（设计）第115页邻室和楼下房间均为空调房间，室温均相同，所以在计算负荷时可以不考虑墙壁传热。外窗参数:选择6mm厚度单层铝合金框架玻璃窗，尺寸为2400mm×2400,2100mm×2400mm、1200mm×1500mm,900×1200两种，传热系数K=3.3W/()，内遮阳系数Cn=0.5，地点修正系数：南面北面，东面和西面，，遮挡系数。 贵州大学本科毕业论文（设计）第115页1.负荷计算1.1负荷计算基本公式内墙、內窗、地板等其邻室为空调房间时，其室温基数差小于3℃时，不计算冷负荷。所以负荷计算时，室温基数差小于3℃的都不用考虑楼板和内墙的传热。1.1.1外墙、屋顶的瞬变传热的冷负荷根据《实用供热空调设计手册》得，在日射和室外气温综合作用下，外墙和屋面瞬变传热引起的逐时冷负荷可按式2.1计算。（公式2.1）式中：计算时间，h；围护结构表面受到周期为24h谐性温度波作用，温度波传到内表面的时间延迟，h；温度波的作用时间，即温度作用于围护结构外表面的时刻，h；——围护结构传热系数，；围护结构计算面积，m2；——作用时刻下，围护结构的冷负荷计算温度，简称冷负荷温度，℃；——负荷温度地点修正值，℃；——室内设计温度，℃。1.1.2内围护冷负荷由于相邻空间通风良好，临室发热量很少，仅由于温差形成内围护冷负荷，属于稳定传热，根据参考资料[1]可得计算公式2.2。（公式2.2）式中：——围护结构传热系数，； 贵州大学本科毕业论文（设计）第115页围护结构计算面积，m2；——夏季空调室外计算日平均温度，℃；——室内设计温度，℃。1.1.1外窗玻璃瞬变传导得热形成的的冷负荷在室内外温差的作用下,玻璃窗瞬传热形成的冷负荷可按式2.3计算。（公式2.3）式中：——窗玻璃的传热系数，；——窗的计算面积，m2；——计算时刻下的冷负荷温度，℃；——地点修正系数，℃；——室内设计温度，℃；a——窗框修正系数。1.1.2玻璃窗日射得热形成的冷负荷透过玻璃窗进入室内的日射得热形成的逐时冷负荷按式2.4计算。（公式2.4）式中：——窗的构造修正系数；——地点修正系数；——内遮阳系数；——计算时刻下，透过有内遮阳设施窗玻璃太阳辐射的冷负荷强度，。1.1.3设备散热冷负荷（公式2.5）式中：F——空调区面积，m2。 贵州大学本科毕业论文（设计）第115页qf——电器设备功率密度，W/m2。1.1.1灯光照明散热形成的冷负荷白炽灯散热形成的冷负荷按照式2.6计算。（公式2.6）式中：同时使用系数，由于缺少实测数据，取=0.6～0.8；——计算时刻，h；——开灯时刻，h；——从开灯时刻算起到计算时刻的持续时间，h；——时刻灯具显热散热的冷负荷系数；——照明灯具所需功率，缺少数据时，可根据空调使用面积推算功率指标W。1.1.2人体散热形成的冷负荷人员的冷负荷包括人员显热和潜热部分，显热部分需要进行逐时计算，而潜热由于变化范围较小，按稳定传热计算。根据参考资料得：a.人体显热形成的计算时刻冷负荷按照公式2.7计算公式。（公式2.7）式中：——不同室温和劳动性质时一名成年男子小时显热散热量，W；计算时刻空调区内的总人数；——群集系数；——计算时刻，h；——人员进入空调区的时刻，h；——从人员进入空调区的时刻算起到计算时刻的持续时间h；——时刻人体显热散热的冷负荷系数。b.人体散湿形成的潜热冷负荷（W）计算公式：（公式2.8）式中：——不同室温和劳动性质时一名成年男子小时潜热散热量，W； 贵州大学本科毕业论文（设计）第115页计算时刻空调区内的总人数；——群集系数。1.1.1空调新风冷负荷（公式2.9）式中：GW——新风量hw——室外焓值KJ/Kghn——室内焓值KJ/Kg1.2夏季冷负荷计算由于个房间设计温度一样，所以负荷计算时不考虑个房间之间的传热，即不用计算内墙的冷负荷。房间1001的围护结构负荷计算如下：北外墙总面积：F=4.4m×7.2m-1.5m×1.8m=28.98㎡北外窗总面积：F=1.5m×1.8m=2.7㎡西外墙总面积：F=7.2m×7.2m=51.84㎡（1）外墙冷负荷由资料查得外墙各系数，W/(),,。查得作用时刻时的北外墙负荷温差的逐时值，按式：算出外墙的逐时冷负荷。(2)内墙负荷：=1.7828.8×(32.5-26)=333.2W1.2.1十层冷负荷表2.1外墙冷负荷北外墙冷负荷（W）时刻τ9：0010：0011:0012:0013:0014:0015:0016:0017:00

贵州大学本科毕业论文（设计）第115页1.工况分析1.1夏季工况分析（1）、根据室内空气hn线、新风处理后机器露点的相对湿度和风机温升可定出新风处理后的机器露点L和温升后的K点。（2）、确定机器露点L和考虑温升后的状态点K，从N点引hN线，取温升为1.5℃的，使KL线段与等焓线h线和=90%线分别交于K、L，连接，在h-d图上读得L点焓值为=60.5，是新风在新风机组内实现的冷却减湿过程。图3.1空气处理过程1.1.1送风量确定已知1001房间室内状态点N为：,,=61KJ/Kg，=13.7g/Kg。冷负荷Q=2323.9W，湿负荷为W=2109=218g/h=0.0606g/s。所以热湿比ε=Q/W=2323.9/0.0606=26274，送风温差为6度，采用机器露点送风，送风状态点=55KJ/Kg,=20℃。总送风量为：G=Q/(hn-ho)=2323.9/(61-55)=387.3g/s=1394.4kg/h=1162m3/h（1）、按卫生要求：客房共2人，新风量每人每小时30m³，所以每小时向办公室房间供给的新风量为=60m³。（2）、按补充局部排风：因为没有局部排风装置，所以=0. 贵州大学本科毕业论文（设计）第115页（3）、按保持空调房间的“正压”要求：取送风次数n=1，则：=1×7.2×4×7.2=207.4m³=+=207.4m³=0.1G=116.2m³取、、中的最大值为=223.5m³，所以新风百分比：m%=207.4÷1162=17.8%>10%满足要求。同理可得其他各房间风量,如表3.1。表3.1各房间新风量房间号新风量（g/s）新风量（m³/h）总风量（g/s）总风量（m³/h）新风比门厅138.2414.744413320.31房间20146.07138.2365.81097.40.13房间20246.07138.2336.11008.30.14房间20346.07138.2336.11008.30.14房间20446.07138.2365.81097.40.13房间205344.0010322377.57132.50.14房间206120.00360938.72816.00.13房间20746.07138.2400.61201.70.12房间301216.006481182.63547.80.18房间30286.33259621.41864.30.14房间303216.006481182.63547.80.18房间304168.005041017.23051.60.17房间305168.005041017.23051.60.17房间4-5-01103.67311824.32472.90.13房间4-5-0269.13207.4549.51648.60.13房间4-5-0369.13207.4549.51648.60.13

贵州大学本科毕业论文（设计）第115页1.空调方案确定和设备选型1.1空调系统的分类方案确定空调系统按负担室内空调负荷所用介质分类，可分为全空气系统、全水系统、空气-水系统和冷剂式系统。一、全空气系统是指室内空调负荷全部由处理过的空气负担。系统适用性：1、建筑空间大，易于布置风道；2、室内温、湿度、洁净度控制要求严格；3、负荷大或潜热负荷大的场合。二、全水系统是指室内空调负荷全部由水来负担。系统适用性：1、建筑空间小，不宜于布置风道；2、不需通风换气的场所。三、空气-水系统是指室内空调负荷由空气和水共同负担。1、室内温、湿度要求一般的场合；2、层高较低的场合；3、冷负荷较小、湿负荷也较小的场所。四、冷剂式系统是指空调房间负荷由制冷剂直接承担。1、空调房间布置分散；2、要求灵活控制空调使用时间；3、无法集中设置冷热源。 贵州大学本科毕业论文（设计）第115页全空气一次回风系统的空调机组送风量是恒定的，系统的夏季冷量由室内冷负荷、新风负荷和再热负荷组成，对于送风温差无严格要求的舒适性空调，如采用大温差送风即露点送风的一次回风系统，可不需要消耗再热量，因此可节省能耗。但送风温差过大，往往会造成送风口解霜现象，为避免此类现象的发生，采用一次回风空调系统需利用再热来解决送风温差受限制的问题，即为了保证必须的送风温差，一次回风系统在夏季需要再热，从而产生冷热抵消的现象风机盘管加新风系统是空气-水系统的一种主要形式，也是我国民用建筑中采用最普遍的一种空调方式，它的投资少，使用灵活和节省建筑空间等优点被广泛应用于各类建筑中。该系统具有以下特点：本设计为培训中心，通过对上述空调系统的分析，本设计采用空气-水系统。新风系统的形式采用分楼层水平式，每层设置新风系统，采用风机盘管加新风系统，新风处理方式不一样，对室内空气品质有很大的影响。风机盘管加新风系统的空气处理方式有：（1）新风处理到室内状态的等焓线，不承担室内负荷；（2）新风处理到低于室内空气的焓值，并低于室内空气的含湿量，承担部分室内负荷。这里选用不承担室内冷负荷方案，在每层的空调机房处设置一新风处理机组，负担新风负荷，新风不与风机盘管回风混合，新风口单独送风。1.1.1水系统表4.1系统方案比较类型特征优点缺点闭式管路系统不与大气相接触，仅在系统最高点设置膨胀水箱。设备腐蚀小，不需克服静水压力，水泵压力，功率低，系统简单。与蓄热水池连接较复杂。开式管路系统与大气相通。与蓄热水池连接较简单。易腐蚀，输送能耗大。同程式供回水干管中的水流方向相同，经过每一管路的长度基本相等。水量分配，调度方便，便于水力平衡。需设回程管，管道长度增加，初投资稍高。 贵州大学本科毕业论文（设计）第115页续表类型特征优点缺点异程式供回水干管中的水流方向相反，经过每一管路的长度不相等。不需设回程管，管道长度较短，管路简单，初投资稍低。水量分配，调度较难，水力平衡较麻烦。两管制供热，供冷合用同一管路系统。管路系统简单，初投资省。无法同时满足供热和供冷的要求。三管制分别设置供冷、供热管路与换热器，但冷热回水的管路共用。能同时满足供冷、供热的要求，管路系统较四管制简单。有冷热混合损失，投资高于两管制，管路系统布置较简单。四管制供冷、供热的供、回水管均分开设置，具有冷、热两套独立的系统。能灵活实现同时供冷或供热，没有冷、热混合损失。管路系统复杂，初投资高，占用建筑空间较多。单式泵冷、热源侧与负荷侧合用一组循环水泵。系统简单，初投资省。不能调节水泵流量，难以节省输送能耗，不能适应供水分区压降较悬殊的情况。变水量系统中的供回水温度保持定值，负荷变化时，通过改变供水量的变化来适应。输送能耗随负荷的减少而降低；配管设计，可以考虑同时使用系数，管径相应减少；水泵容量、电耗相应的减少。系统复杂；必须配备自控设备。

贵州大学本科毕业论文（设计）第115页1.房间的气流组织计算1.1气流组织计算采用散流器平送气流组织形式，径向贴附散流器，送出的气流为贴附于顶棚的射流，回风口布置在房间下部。因散流器服务的长宽比大于1.25时，采用矩形散流器。散流器中心与侧墙的距离不小于1m。房间尺寸为7.2×4×3.6（长×宽×高），（以901房间为例）。（1）、按两个散流器布置，则散流器所对应的Fn=4×3.6=14.4㎡，水平射程分别为2m及1.8m,平均取=1.9m,垂直射程=3.6-2=1.6m.（2）、设送风温差=6℃，因此总送风量为L=1743.5×3.6÷（1.2×1.01×6）=863.1m³/h换气次数：n=863.1÷（7.2×3.6×4）=8.3l/h按照两个散流器布置，每个散流器的送风量为=863.1/2=431.55m³/h（3）、散流器出风速度选定为3.0m/s，这样：=431.55÷（3.0×3600）=0.04㎡（4）、检查，根据式5.1得到。（公式5.1）式中：=1.41；——根据0.1/=0.1=0.95，查图5-13，按=1.9/1.6=1.188查得=0.49；

贵州大学本科毕业论文（设计）第115页1.1.1空调水系统的设计原则关于空调系统的设计方案，应考虑其坡度，本设计定为0.003，水管材料低压系统，管径不大于50mm时，采用焊接钢管；大于50mm的用无缝钢管。冷凝水管采用塑料管，不宜采用焊接钢管；管道需要保温，保温前刷两道防锈底漆。1.1.2水管的水力计算冷冻水管路设计计算步骤：1）绘制空调系统轴测图，并对各管段进行编号、标注长度和风量。2）根据各房间的的冷负荷，计算各管段的流量公式为：（公式6.1）式中：G—管段流量，，；Q—房间的冷负荷，kw；c—水的比热容，取4.19kJ/kg﹒℃；—水的密度，取1000kg/m3；—供回水温差，℃，查=5℃3）管径的确定根据假定的流速和确定的流量计算出管径公式为：（公式6.2）再根据给定的管径规格选定管径，由确定的管径计算出管内的实际流速，公式为：（公式6.3）4）阻力计算ⅰ.沿程阻力计算公式为：（公式6.4）式中：R—单位管长的摩擦阻力，Pa/m；L—直管段长度，mⅱ.局部阻力计算公式为:（公式6.5）式中：—局部阻力系数，由《实用供热空调设计手册》得到。

贵州大学本科毕业论文（设计）第115页1.1膨胀水箱大小的计算对于空调水系统为闭式系统时，为使系统中的水因温度变化而引起的体积膨胀的余地，以及有利于系统的空气的排除，所以在系统中设置一个膨胀水箱，连接在水泵的吸入侧，也即在排水管道上，本设计采用闭式水箱。膨胀水箱的容积由下式计算：（公式7.3）式中：Vp——膨胀管有效容积。即从信号管到溢流管之间高差内的容积（m3）；α——水的容积膨胀系数，取0.0006L/℃；Δt——最大的水温变化值（℃），取30℃。Vs——膨胀水箱系统的水的容量，即系统中管道和设备内总水容量。Vs可以按照经验值计算，按照供冷时每立方米为1.3升计算，由实际建筑面积为8997.12m3，可以估算出Vs=11696.3L，代入上式中Vp=0.21m³。选择方形膨胀水箱。表7.4膨胀水箱尺寸公称容积m30.5外形尺寸mm水箱配管的公称直径mm有效容积m30.61长宽高溢流管排水管膨胀管信号管循环管水箱自重kg156.39009009004032252020 贵州大学本科毕业论文（设计）第115页1.空调系统的消声、保温、防腐、减振与防火排烟1.1空调系统的消声空调系统中的主要噪声源是通风机。通风机噪声的产生和许多因素有关，尤其与叶片形式、片数、风量、风压等参数有关。风机噪声是由叶片上紊流而引起的宽频带的气流噪声以及相应的旋转噪声，后者可由转数和叶片数确定其噪声的频率。在通风空调所用的风机中，按照风机大小和构造不同，噪声频率大约在200～800Hz（即主要噪声处于低频范围内）。所以，可以在新风机组出口处安装一个共振型消声器以达到消除低频噪声的目的。空调系统的噪声源除风机外，还有由于风管内气流压力变化引起钢板的振动而产生的噪声。尤其当气流遇到障碍物（如阀门）时，产生的噪声更大。在高速风管中这种噪声不能忽视，而在低速系统中，由于管内风速的选定已考虑了声学因素所以可不必计算。此外，由于出风口风速过高也会有噪声产生，所以在气流分布中都适当限制出风口的风速。1.2空调系统的保温和防腐1.2.1保温的类型保热：热水系统，蒸汽管道等；保冷：新风系统风管，冷冻水供回水管等；1.2.2 保温的目的（1）为了避免空调系统因冷、热损耗大，造成经济上的不合理；（2）为了避免由于冷、热损失，使介质温度达不到要求温度，因而不能保证室内参数；（3）为了避免当管道穿过室内参数要求严格的空调房间，而管道散出的冷热量对室内参数影响不利； 贵州大学本科毕业论文（设计）第115页（4）为了避免管道的冷表面结露。1.1.1空调系统使用的保温材料常用的保温材料有：岩棉、离心玻璃棉、橡塑海绵、阻燃聚乙烯泡沫塑料、硬质聚氨酯泡沫塑料等.表8.1常用保温材料参数种类密度kg/m3导热系数w/m-K吸水率g/100cm2透湿系数g/m2-s-Pa防火性能参考价格元/m2备注岩棉1000.03883.31.3x10-5不燃烧板材600管壳900防水防腐性较差离心玻璃棉480.03-0.03825(%随重量增加)4x10-5不燃烧棉毡750管壳1250-橡塑海绵870.0380.4-阻燃性FV-0级11000-

贵州大学本科毕业论文（设计）第115页空调系统的噪声除了通过空气传播到室内外，还能通过建筑物的结构和基础进行传播。而要削弱由机器传给基础的振动，只能消除它们之间的刚性连接。即在振源和它的基础之间安设避振构件（如弹簧减振器或橡皮、软木等），可使从振源传到基础的振动得到一定程度的减弱。1.1空调设计与防火排烟空调工程中，火灾时风道成为烟气扩散通路的情况时有发生，由于空调直接连接于房间与房间之间，所以传播烟气的危险性很大。另外，风道的断面积比电气或给排水配置要大，也是容易引起烟气传播的因素。建筑物一旦起火，要立即使用各种消防设施，隔绝新鲜空气的供给，同时切断燃烧的部位等。因为消防灭火需要一定的时间，当采取了以上措施后，仍不能灭火时，为确保有效的疏散通路，必须具备防烟措施。为了防止火灾扩大，在建筑设计中需对空调建筑进行防火，可根据房间用途和性质的不同对建筑物设置防火墙、防火门、防火卷帘等设备。在一般的建筑物中，我们可以在出风口上安装防火阀，所以，在该栋宿舍楼中，在新风机组出口的地方安装上70℃的防火阀即可。
