本科毕业设计正文1前言本次设计的对象为某酒店中央空调系统，地点在舟山。随着改革开放的深入，作为第三产业的旅游业获得较大的发展。与之相应，高层酒店建筑在全国各地普遍兴建。除新建大批项目之外，对老酒店的改建、改造也相继大踏步地进行。高层酒店建筑普遍内外装饰华丽，使用功能齐全，并普遍装有全年性舒适空调。高层酒店齐全的使用功能，对空调系统也提出了更为复杂的要求。如果空调系统不能很好的满足要求，达到各功能分区的室内舒适性空调设计参数，就将导致酒店不能达到预定等级，影响酒店声誉，并直接关系到客源和酒店的经济效率。此外，酒店的空调能耗非常大，约占酒店建筑能耗的60%，酒店空调系统的节能将直接关系到经营成本。总之空调系统的优劣对酒店经营的重要性是不言而明的。客房是酒店建筑的重要组成部分，是酒店经营的主体。客房面积一般约占建筑总面积的30%～45%，所以必须有一个适当灵活的调节范围，能够满足不同客人对于温湿度的不同要求。公共用房和康乐中心是对于酒店功能的补充和完善。酒店的公共用房和康乐中心不仅为住酒店客提供服务，而且也为非住店客人提供服务。因此酒店的公共用房通常布置在大楼的底层几层。公共部分和康乐中心的人员密度大，建筑内部散热量大，其装设空调的容量比客房大。76 本科毕业设计正文2建筑概况及工况设定本次设计是的建筑是位于美丽的海滨城市舟山的一个商务酒店。该建筑是一个五层的酒店，第一层是用于一个KTV的公共娱乐场所，2-5层则是用于客房，客房是该酒店的主要的组成部分，一般约占建筑总面积的45%。该建筑各层的具体面积如表1：表2-1建筑面积表客房（）KTV（）一层810二层810三层810四层810五层810根据图纸上的测量，一层层高为3.9m,二-五层层高均为3.6m（包括楼板厚度）。76

本科毕业设计正文4设计方案的确定4.1确定空调系统由于1层是一个KTV格局与2~5层相同都是小空间的格局，所以该酒店整个的运用风机盘管加独立新风的方式进行调控。此种空调方式是现在公认的最普遍便、最适用于客房这种小空间使用的方式，它不仅布置灵活、运行费用低，各个房间还能单独地进行调节。与全空气系统相比更加节约了建筑空间，它的机组定型化、规格化，易于选择型号，更加易于安装。而该酒店的空间也是最适宜应用这种空调方式，所以我们选择了这种风机盘管加独立新风的方式。而该空气调节方式的处理方式是新风承担较大湿负荷，使室内风机盘管尽可能在析湿量小的工况下运行，对于卫生要求和运行安全较为有利。该设计新风不承担室内冷负荷，选用新风处理到室内状态的等焓线。4.2确定水系统空调水系统如果选用两管制变流量系统，夏季供冷与冬季供热利用同一对管路。这样，既节省管道占用空间又大大节约了管道造价。但也存在不足，即不能同时在不同地方供冷和供热；不能再过度季或冬季提供内区供冷周边区供热，难以适应房间负荷的各种变化，不能满足实际运行需要。空调水系统如果改为四管制可以克服以上缺点，但这种水系统的管道设备比起两管制几乎要增加一倍，不但管道设备占用空间大，而且造价大大增加，运行费用也有所提高，且既要开启制冷机又要开启供热锅炉。经过反复的比较，结合酒店的具体情况，结合实际情况相结合最终采取了分区两管系统.风机盘管的冷冻水供、回水温度一般取7℃/12℃，温差为5℃。风机盘管凝结水管的泄水坡度，不宜小于0.01。风机盘管水系统水平管段和坡度的最高点，应设排气装置。风机盘管安装在顶棚中，送风在前部，回风口在下部或后部。76 本科毕业设计正文5负荷计算在室内外热、湿扰量作用下，某一时刻进入一个恒温恒湿房间内的总热量和湿量称为在该时刻的得热量和得湿量。当得热量为负值时称为耗（失）热量。在某一时刻为保持房间恒温恒湿，需要向房间供应的冷量称为冷负荷；相反，为补偿房间失热而需要向房间供应的热量称为热负荷；为维持室内相对湿度所需由房间出去或增加的湿量称为湿负荷。得热量通常包括以下几个方面：（1）由于太阳辐射进入的热量和室内外空气温差经维护结构传入的热量；（2）人体、照明设备、各种工艺设备及电气设备散入房间的热量[2]。5.1负荷计算公式瞬变传导得热和冷负荷当忽略窗户热容时，则各阶谐波的温度波衰减度均为,相位延迟，对应于室内外空气温度的多阶谐波展开式的瞬变传热得热量为公式中——n阶室外空气温度的波幅，℃。相应的冷负荷公式中，——房间对n阶窗户传导得热中辐射扰量的衰减度和相位延迟，deg;F——窗户面积，。日射得热和冷负荷日射得热量分成两部分：直接射透到室内的太阳辐射热和被玻璃吸收的太阳辐射热传向室内的热量。日射得热取决于很多因素，从太阳辐射方面来说，辐射强度、入射角均依纬度、月份、日期、时间的不同而不同。为了方便计算，可先确定厚度为3mm的普通平面玻璃作为“标准玻璃”。在特定的内外表面放热系数（和）条件下，得出我国40个城市夏季九个不同朝向的单位面积日射得热量，称之为日射得热因数，既。对于非标准玻璃，以及不同遮阳设施，采用修正的办法，即公式中——窗玻璃的遮挡系数；——窗内遮阳设施的遮阳系数。当把日射得热因数用实用调和分析整理成谐波形式后，日射得热可表示为公式中——n阶日射得热因数谐波的波幅。76 本科毕业设计正文相应的冷负荷公式中，——房间对n阶窗户日射得热中辐射扰量的衰减度和相应延迟，deg。外墙和屋顶将公式写成以下形式公式中——计算时间，h;——维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，即温度波作用于维护结构外表面的时间，h；K——维护结构传热系数，；F——维护结构计算面积，；——作用时刻下，维护结构的冷负荷计算温差，简称负荷温差。负荷温差按照外墙和屋面的传热衰减系数进行分类。维护结构愈厚、重（热容量愈大），则v值愈大，值愈小；维护结构愈轻、薄（热容量愈小），则v值愈小，值愈大。值在0与1之间变化。当维护结构时，由于结构具有较大的惰性对与外界扰量反应迟钝，从而使负荷温差的日变化很小，为了简化计算，可按平均负荷温差计算冷负荷[3]。墙体外表面的日射吸收率取，如有必要按不同的值查取负荷温差时，可按下式对表列负荷温差进行修正：某值的负荷温差公式中——表列0（水平）朝向的负荷温差，℃。在工程计算时，作为安全考虑，一般可不进行修正。窗户按前述可知，窗户应将瞬变传导得热和日射得热形式的冷负荷分开计算。窗户瞬变传导得热形式的冷负荷公式中——表列0（水平）朝向的负荷温差，℃。因传导负荷只与气温有关，故按最热月的日较差分区。窗户热容小，传热系数较大，故负荷温差按日较差0.5℃。当所计算的城市室外平均气温与制表地点不同时，应适当修正。F为窗口面积。窗户日射得热形成的冷负荷公式中——窗的有效面积系数；单层钢窗0.85，双层钢窗0.75；单层木窗0.7，双层木窗0.6；76 本科毕业设计正文——地点修正系数；——计算时刻时，透过单位窗面积的太阳总辐射形成冷负荷，简称负荷强度，。照明设备散热一层是KTV用面积指标法进行计算，取负荷概算指标为15。二层为客房用面积指标法进行计算，有一个办公室，取负荷概算指标为为60，其他的都为客房，取负荷概算指标为15。三到五层为客房用面积指标法进行计算，取负荷概算指标为15。工艺设备散热电动设备是指由电动机拖动的生产工艺设备。不论这些生产工艺设备怎么样工作的，电动机消耗的电能最终也必定变成热能。用于用电设备的电能也最终会变成热能散出。如果没有局部通风设备排热，就会向室内散热[4]。本设计的空调房间内所安装的电子设备主要是电脑、电视、音响等，其散热形成的冷负荷：公式中——电子设备的功率，KW；——利用系数，——负荷系数；　　　　　　　　——同时使用系数，　　　——效率；　　　　　　　　　　　　　CLQ——设备和用具散热冷负荷系数，人体散发的冷负荷人体散热冷负荷计算公式：公式中——不同室温和劳动性质成年男子小时潜热散热热量，W；——室内全部人数；——群集系数。表5-1西窗瞬时传热冷负荷计算时刻8:009:0010:0011:0012:0013:0014:0015:0016:004.25.26.27.18.08.69.19.39.632.8836.344.953.661.369.174.378.680.482.9该酒店用单层钢窗，它的传热系数K=3。表5-2西窗日射得热冷负荷计算时刻8:009:0010:0011:0012:0013:0014:0015:0016:0046.959.972.981.986.9141.9249.9341.9391.952.88132.3172.7210.1236250.4408.8719.99841128.8西外窗总和168.6217.6263.7297.4319.5483.1798.510651211.876

本科毕业设计正文6房间新风量与送风量的确定室内余热量（即室内冷负荷）为Q(W)，余湿量为W（）。为了消除余湿余热，保持室内空气状态为N,送入G（）的空气；其状态为O.当送入空气吸收余热Q和余湿W后，由状态O(、)变为状态N（、）而排出，从而保证室内空气状态[3]。根据查资料选定送风温差之后，即可按以下步骤确定送风状态和计算风量：（1）在h-d图上找出室内空气状态点N；根据算出的Q和W求出热湿比，在通过N点画出过程线；根据所取定的送风温差求出送风温度，等温线与过程线的交点O即为送风状态点；根据计算送风量。这样就能确定送风量了。既然在处理空气时大多数场合要利用相当一部分回风，所以，在夏、冬季节混入的回风量愈多，使用的新风量愈少，就愈显得经济。但实际上，不能无限制的减少新风量，一般规定，空气系统中新风占送风量的百分数不应低于10%。确定新风量的依据有下列三个因素：（1）卫生要求在实际工作中，一般可按规范确定：不论每人占房间体积多少，新风量按大于等于30人）采用；对于人员密度的建筑物，如采用空调的体育馆、会场，每人所占的空间较少（不到10）但停留时间短，可分别按吸烟或不吸烟的情况，新风量以7~15人）计算。由于此类建筑物按此确定的新风量占总风量的百分比可达30%~40%，从而对冷量影响很大，所以确定新风量时耀十分谨慎。（2）补充局部风量当空调房间内有排风柜等局部排风装置时，为了不使车间产生负压，在系统中必须有相应的新风量来补充排风量。（3）保持空调房间的“正压”要求为防止外界环境空气（室外的或相邻的空调要求较低的房间）渗入空调房间，干扰空调房间内温湿度或破坏室内洁净度，需要在空调系统中用一定量新风来保持房间的正压（即室内大气压力高于外界环境压力）。在实际工程设计中，对于绝大多数场合来说，当按照新风量不足总风量的10%，也按10%来计算，以确保卫生和安全[5]。76

本科毕业设计正文（一）选定送风口型式，确定紊流系数a；布置送风口位置，确定射程x。（二）选取送风温差，计算送风量和换气次数。送风温差及换气次数与室温允许波动范围有关。（三）确定送风口的出流速度。送风口的出流速度是根据以下两条原则确定的：1.应使回流平均速度小于工作区的允许流速。工作区允许速度根据工艺要求而定，在一般情况下可按0.25m/s考虑。2.在空调房间内，为防止风口的噪音，限制送风速度在2~5m/s范围内。7.1一层气流组织计算以房间1为例送风口采用双口百叶风口，紊流系数，风口布置在房间宽上风口中心距顶板0.5m,为房间净高的0.5/3.9=0.128＜0.3属于贴附射流，射流的射程x=5.4-0.5=4.9m。根据规范要求选定送风温差为7℃，计算送风量并校核换气次数。次/h确定送风速度，假定送风速度取射程x的轴心温差送风口面积为：风口尺寸为m面积当量直径为校核贴附长度查得，贴附长度其余房间如该房间计算，计算过程省略。表7-1一层气流组织计算表FLnfAr76

本科毕业设计正文9水管水力计算流体输配官网水力计算的主要目的是根据要求的流量分配，确定管网的各段管径（断面尺寸）和阻力，求得管网特性曲线，为匹配管网动力设备准备好条件，进而确定动力设备（风机、泵等）的型号和动力消耗。本次的水力计算采用假定流速法。假定流速法的特点是，先按技术经济要求选定管内流速，再结合所需输送的流量，确定管道断面尺寸，进而计算管道阻力，得出需要的动力。假定流速法适用于动力未知的情况[6]。具体步骤如下：（1）绘制管网轴测图，对各管段进行编号，标出长度和流量，确定最不利环路;（2）合理确定最不利环路各管段的管内流体速度;（3）根据各管段的流量和确定的流速，确定最不利环路各管段的断面尺寸;（4）计算最不利环路各管段的阻力;（5）平衡并联管路，这是保证流量按要求分配的关键;（6）计算管网的总阻力，求取管网特性曲线;（7）根据管网特性曲线，所要求输送的总量以及所输送流体的种类、性质等诸因素，综合考虑为管网匹配动力设备，确定动力设备所需的参数;首先初步估算以确定供回水管布管方式。然后根据工程设计上采用的数值：,；,；,；，。用这种假定流速法，去查管道水力计算表得管径和比摩阻。本次设计采用的水管为塑料管[9]。76

本科毕业设计正文10.2膨胀水箱的选取当空调水系统为闭式系统时，为使系统中的水因温度变化为引起的体积膨胀给予余地，以及有利于系统中空气的排除，在管路中应连接膨胀水箱。为保证在机械循环系统中，膨胀水箱应接在水泵的吸入侧，水箱标高应至少高出系统最高点1。膨胀水箱的容积是由系统中水容量和最大的水温变化幅度决定的，可由下式计算：式中——膨胀管有效容积，即从信号管到溢流管之间高差内的容积；——水的体积膨胀系数，=0.0006;——最大的水温变化值，45－6＝39（℃）；——膨胀水箱的水容量，即系统中管道和设备内总容水量，查得=1.3所以，。选择方形膨胀水箱THX-1型。表10-2膨胀水箱的规格尺寸水箱形式型号公称容积()有效容积()外形尺寸()水箱自重高方形10.50.61900900900156.310.3冷水机组的选取冷水机组是一种能够制造低温水（冷冻水）的设备，可以为空气处理机提供冷源。制冷机的冷却方式有风冷或水冷式两种。风冷式是利用风扇强制进行冷却，而水冷式则是利用水来冷却机组的。大型的冷水机组多采用水冷式，而本酒店采用风冷式是冷水机组。总的冷负荷为各层冷负荷之和Q=22.54+29.44+27.59+27.59+27.59=136.05kW，采用一台LSF161M型冷水机组。表10-3冷水的规格尺寸机组型号制冷量冷凝风机外形尺寸LSF161M161数量功率转速长宽高44*2.296015003650240076 本科毕业设计正文11消声防火隔振11.1消声空调系统的主要噪声源是通风机。通风机的噪声大小和叶片形式、片数、风量、风压等因素有关。风机噪声是由叶片驱动空气产生的湍流引起的宽频带气流噪声，以及相应的旋转噪声所组成[12]。空调系统出了风机为主噪声源外，风道内气流流速、压力的变化，以及管壁和管内障碍物也会引起气流噪声。在高速风道中，这种噪声不容忽视。除此之外，还有电动机和空调设备噪声。噪声的消除主要采用消声器。消声器是由吸声材料按不同的消声原理设计而成的。除了在风道上采用消声器之外，在风管末端送风口上，也可有效的设置消声构件，并与风口相结合，称为各种形式的消声风口。11.2防火1柜式空调器进出空调机房及风管穿越防火墙处均设置了70.动作防火阀，要求防火阀与空调器风机联锁。2空调风、水管保温均采用阻燃型保温材料。3娱乐中心上空设置12台HTF-10#双速高温排烟风机，下设280动作防火阀，要求防火阀强度能满足排烟风机重量。防火阀与风机联锁。平时开低档作排风换气用，火灾开高档作排烟用。76 本科毕业设计正文11.3隔振隔振设计包括设备的基础隔振和管道隔振。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。例如转动的风机和压缩机所产生的振动，可直接传给基础，以弹性波的形式，由机器基础研房屋机构传到室内，又以噪声的形式出现，称为固体声。可以用非刚性连接，来削弱有机器传给基础的振动，即在振源和基础之间设避震构件，如弹簧避震器、橡皮、软木等，是振动得以衰减[13]。通风机，空调机组，热泵均做防震处理。把设备安装在混凝土板上，用防震材料支撑该板，防震材料采用生软木，混凝土板的重量为设备重量的2~3倍，其尺寸应该比设备的底座大50%以上，而且必须使设备的中心于混凝土板的重心小于30cm。12小结空调系统的设计中存在的问题：1计算负荷的时候对于负荷面积指标、湿负荷指标以及人流密度等的选取可能有不确切之处；2气流组织中的一些校核有些未达到要求，由于误差较小就忽略不计了；3风管和水管的局部阻力系数有些选取的不太确切；4风管和水管的阻力平衡水力计算都未进行，由于尝试计算阻力平衡后，阻力都不平衡且算出来的数值与标准相差甚远，故采用加阀门的方式来解决阻力平衡，就不进行阻力平衡的计算。76
