本科論文沈陽(yáng)城市學(xué)院畢業(yè)設(shè)計(jì)（論文）目錄TOC\o"1-2"\h\z\u20481摘要 [20]。分水器是為了幫助空調(diào)區(qū)的流量調(diào)節(jié)和分配，也有利于系統(tǒng)的維護(hù)和運(yùn)行。在選擇集、分水器時(shí)，應(yīng)能使通過(guò)集管的水量保持在0.5～0.8m/s范圍內(nèi)流動(dòng)。集分水器通常選擇管徑在DN200～DN500范圍內(nèi)的無(wú)縫鋼管。本設(shè)計(jì)中選用的是管徑為DN200的無(wú)縫鋼管。10.3安裝閥門球閥、截止閥、蝶閥等是在水系統(tǒng)中常用到的，閥門的選擇應(yīng)適應(yīng)系統(tǒng)的承受水的壓力的能力，至于閥門的型號(hào)，要保持和連接管的管徑一致。如果需有規(guī)定數(shù)量的調(diào)節(jié)水流量時(shí)，選用平衡閥，它還進(jìn)行測(cè)量、關(guān)閉和排放污水。閥門的設(shè)置一般在以下地點(diǎn)：=1\*GB2⑴每個(gè)壓力表的與管子交接處；=2\*GB2⑵每個(gè)支路的出入口、排水管及排氣管上；=3\*GB2⑶熱交換器、加熱器等的進(jìn)出水管；=4\*GB2⑷手動(dòng)操作的旁通閥、雙通閥的兩側(cè)閥口處等。

11通風(fēng)及排煙設(shè)計(jì)=1\*GB2⑴地下一層的設(shè)備機(jī)房，為了達(dá)到排風(fēng)的目的應(yīng)設(shè)置軸流風(fēng)機(jī)，而且還要有補(bǔ)風(fēng)機(jī)進(jìn)行補(bǔ)風(fēng)；=2\*GB2⑵在公共衛(wèi)生間內(nèi)應(yīng)該設(shè)置吊頂式通風(fēng)器，為衛(wèi)生間通風(fēng)換氣；=3\*GB2⑶排煙口平時(shí)保持關(guān)閉狀態(tài)，當(dāng)有火災(zāi)信號(hào)出現(xiàn)時(shí)，閥門自行開(kāi)啟，并連帶排煙風(fēng)機(jī)開(kāi)啟；=4\*GB2⑷在地上各層的無(wú)窗房間和走道的吊頂內(nèi)吊裝排煙風(fēng)機(jī)；=5\*GB2⑸排煙風(fēng)機(jī)入口的前面，安裝排煙防火閥，如果煙氣溫度到了一定值熔斷時(shí)，閥門因此而自動(dòng)關(guān)閉，并連帶將排煙風(fēng)機(jī)關(guān)閉；=6\*GB2⑹排煙設(shè)計(jì)時(shí)，其管道及其他附件等的制作一定選用不會(huì)燃燒的材料，排煙管道一定要注意防火、隔熱，并且要與易燃燒的物質(zhì)控制一定的距離，通常來(lái)說(shuō)在150mm范圍之外。

12管道的保溫與防腐12.1管道的保溫12.1.1保溫目的=1\*GB2⑴讓系統(tǒng)冷量和熱量能夠更有效的被利用，降低能量損失，確?？照{(diào)的設(shè)計(jì)和操作；=2\*GB2⑵風(fēng)道表面的溫度高于或等于附近的空氣溫度，讓表面上有露水，加速傳熱，同時(shí)防止和抑制腐蝕空調(diào)風(fēng)管結(jié)露。12.1.2選用保溫材料因?yàn)閷?dǎo)熱系數(shù)對(duì)保溫材料的熱工性能影響很大，導(dǎo)熱系數(shù)小的保溫材料其保溫效果好。在本次設(shè)計(jì)中，保溫材料選用離心玻璃棉保溫管材（難燃B1級(jí)），厚度為40mm。12.1.3保溫水管的厚度空氣凝結(jié)水管厚度6mm，冷熱水管的厚度如表12.1所示。表12.1冷熱水管保溫厚度水管管徑保溫厚度mm≤4050―100125―25035404512.2管道的防腐在本設(shè)計(jì)中，除掉非鍍鋅鋼管表面的銹之后，需要刷防銹漆對(duì)其進(jìn)行保護(hù)，如果管道采用明裝，其表面需要涂銀粉，如果管道是鍍鋅鋼管，當(dāng)其表面有破損時(shí)，那么破損處應(yīng)先刷防銹漆再刷銀粉進(jìn)行保護(hù)。

13消聲減震設(shè)計(jì)13.1消聲設(shè)計(jì)空調(diào)系統(tǒng)在運(yùn)行過(guò)程中，通風(fēng)機(jī)、制冷機(jī)等會(huì)產(chǎn)生的噪聲，此外，設(shè)備也會(huì)產(chǎn)生噪聲傳播到房間內(nèi)，影響生活和工作環(huán)境。如果空調(diào)房間內(nèi)對(duì)噪聲要求高，通風(fēng)系統(tǒng)的噪聲衰減是不可缺少的。管道系統(tǒng)消聲設(shè)計(jì)的基本原則如下：=1\*GB2⑴如果直接在機(jī)房?jī)?nèi)布置消聲器，應(yīng)針對(duì)其設(shè)置檢修門和風(fēng)管。因?yàn)橹黠L(fēng)道內(nèi)的風(fēng)速很大，如果消聲器近距離設(shè)置在風(fēng)道附近，那么必會(huì)增加噪聲；=2\*GB2⑵消聲器的類型多種多樣，而對(duì)于消聲器的選擇，應(yīng)按照系統(tǒng)需要的消聲量等因素綜合考慮，再根據(jù)技術(shù)經(jīng)濟(jì)對(duì)比情況去選定；=3\*GB2⑶消聲彎頭等這類消聲器在消聲設(shè)計(jì)中必不可少，要加以利用。13.2減震設(shè)計(jì)新風(fēng)機(jī)組，通風(fēng)機(jī)等需吊裝搭設(shè)，采用軟管連接機(jī)組與風(fēng)管。為讓其更穩(wěn)固，隔振底座是必不可少的。將水泵，熱泵機(jī)組在其上固定。隔振基座質(zhì)量的決定因素取自實(shí)驗(yàn)數(shù)據(jù)。泵底座采用彈簧復(fù)合減振器，管路連接靈活。由于熱泵機(jī)組重，基礎(chǔ)承載力不小于運(yùn)行重量的1.5倍。橡膠墊或減震器底座可直接設(shè)置在機(jī)座下方。

結(jié)論本設(shè)計(jì)課題是辦公樓內(nèi)空調(diào)系統(tǒng)的設(shè)計(jì)，建筑內(nèi)主要有辦公室、會(huì)議室等功能間。設(shè)計(jì)主要包括建筑的負(fù)荷計(jì)算、空調(diào)方案的確定、設(shè)備的選型、水系統(tǒng)的設(shè)計(jì)、水力計(jì)算等。綜合運(yùn)用所學(xué)知識(shí)，將專業(yè)技能運(yùn)用到畢業(yè)設(shè)計(jì)中。學(xué)會(huì)分析問(wèn)題、解決問(wèn)題，提升了專業(yè)素養(yǎng)。按照負(fù)荷計(jì)算和各種方案的對(duì)比，確定建筑室內(nèi)選擇風(fēng)機(jī)盤管加新風(fēng)系統(tǒng)。空氣處理機(jī)組位于吊頂上。氣流組織選用上送下回的形式，送風(fēng)口采用方形擴(kuò)散器和雙層百葉送風(fēng)口。在水力計(jì)算中，選擇假定流速法，并對(duì)計(jì)算結(jié)果進(jìn)行了校核。系統(tǒng)在機(jī)房?jī)?nèi)定壓通過(guò)定壓罐來(lái)完成。設(shè)計(jì)過(guò)程中考慮保溫，減震，防煙措施。由于缺少更多的實(shí)踐經(jīng)驗(yàn)，本次的設(shè)計(jì)有不足之處，日后勤加學(xué)習(xí)，增強(qiáng)專業(yè)能力。參考文獻(xiàn)趙榮義,錢以明.空氣調(diào)節(jié)[M],第3版.北京:中國(guó)建筑工業(yè)出版社,2016.12：345-380唐春成.某超高層辦公樓空調(diào)系統(tǒng)設(shè)計(jì)[J].制冷,2017,36(01)：46-52孫偉.淺談設(shè)計(jì)院辦公樓空調(diào)通風(fēng)系統(tǒng)工程實(shí)例[J].中國(guó)新技術(shù)新產(chǎn)品,2018,(05)：70-71孫一堅(jiān).簡(jiǎn)明通風(fēng)設(shè)計(jì)手冊(cè)[M],第2版.北京:中國(guó)建筑工業(yè)出版社,2016.3：105-120何小兵.高檔辦公樓工程項(xiàng)目中的節(jié)能型空調(diào)系統(tǒng)設(shè)計(jì)[J].建筑施工,2016,38(08)：1102-1104楊迎七.某辦公樓變風(fēng)量空調(diào)系統(tǒng)控制設(shè)計(jì)探討[J].建筑熱能通風(fēng)空調(diào),2017,36(08)：56-59劉亮.蕪湖市某辦公樓地源熱泵空調(diào)系統(tǒng)設(shè)計(jì)[J].安徽建筑,2016,23(02)：211-213李欣煜.某高層辦公樓空調(diào)系統(tǒng)設(shè)計(jì)的幾點(diǎn)體會(huì)[J].中國(guó)住宅設(shè)施,2015,(03)：95-97徐猛.成都某辦公樓空調(diào)系統(tǒng)節(jié)能設(shè)計(jì)[J].制冷與空調(diào)（四川）,2016,30(02)：229-231周懷改.北京某數(shù)據(jù)中心辦公樓暖通空調(diào)設(shè)計(jì)案例分析[J].科技創(chuàng)新與應(yīng)用,2016,(28)：257-258雷會(huì)玉,余曉明,朱祥政,張曉.辦公樓輻射空調(diào)系統(tǒng)方案設(shè)計(jì)[J].制冷技術(shù),2014,34(05)：72-76戴銀寶.上海某辦公樓變風(fēng)量空調(diào)系統(tǒng)設(shè)計(jì)[J].建筑技術(shù)開(kāi)發(fā),2016,43(02)：82-85萬(wàn)海生.辦公室暖通空調(diào)系統(tǒng)節(jié)能設(shè)計(jì)[J].中華民居,2014,000(012)：29-30付剛,林佳佳.某辦公樓變風(fēng)量空調(diào)系統(tǒng)設(shè)計(jì)及運(yùn)行分析[J].制冷與空調(diào)（四川）,2015,29(02)：162-165何高明.中山市某辦公樓空調(diào)系統(tǒng)設(shè)計(jì)分析[J].供熱制冷,2011,000(010)：64-66裴娜,王莉,陳博文.某辦公樓VRV空調(diào)系統(tǒng)方案設(shè)計(jì)[J].科技風(fēng),2014,(20)：141-142唐雄斌.廣東某超高層辦公樓空調(diào)水系統(tǒng)設(shè)計(jì)[J].制冷與空調(diào)（四川）,2016,30(01)：33-35丁帥,孟慶龍,王博聞.變風(fēng)量空調(diào)系統(tǒng)送風(fēng)管道靜壓特性的實(shí)驗(yàn)研究[J].流體機(jī)械,2017,45(1)：66-71ZhuangXL,WuC.Savingenergywhenusingairconditionersinoffices-Behavioralpatternanddesignindications[J].InternationalJournalofEnergyResearch,2014,76(5)：661-668ZhengQianFeng,ChongChaoPan.TheCentralAir-ConditioningEnergySavingSystem[J].AdvancedMaterialsResearch,2016,6(4)：71-79附錄1負(fù)荷計(jì)算樓層房間面積m2最大冷負(fù)荷時(shí)刻房間最大冷負(fù)荷(含新風(fēng)/全熱)W工程負(fù)荷最大值時(shí)刻(13點(diǎn))的各項(xiàng)負(fù)荷值總冷負(fù)荷(含新風(fēng)/全熱)W室內(nèi)冷負(fù)荷(不含新風(fēng)/全熱)W新風(fēng)冷負(fù)荷W總濕負(fù)荷kg/h新風(fēng)濕負(fù)荷kg/h總冷指標(biāo)(含新風(fēng))W/m2新風(fēng)冷指標(biāo)W/m2總濕指標(biāo)kg/hm2新風(fēng)量m3/h一層10124.2703164.333066.35755.342311.012.622.18126.3495.220.11291.24102370.47046192.3345522.5610246.0235276.5439.9633.34122.8895.220.114445.6410314.5401829.331767.79383.281384.511.571.31121.5895.220.11174.4810439.77135086.055086.051299.113786.944.293.58127.8995.220.11477.2410539.44135042.045042.041286.533755.524.253.55127.8495.220.11473.2810639.26135022.025022.021283.653738.384.233.53127.9295.220.11471.1210740.34135172.575172.571331.353841.224.353.63128.2295.220.11484.0810825.8303195.623088.35628.792459.562.792.32119.5695.220.11309.9610925.5503160.983054.87621.972432.902.762.30119.5695.220.11306.6011025.6103168.413062.05623.432438.612.762.30119.5695.220.11307.3211110.901348.521303.25265.341037.911.180.98119.5695.220.11130.8011225.9603211.714734.181410.023324.173.773.14135.6195.220.11418.9211384.99010856.210467.202374.378092.849.177.65123.1695.220.111019.8811476.961310005.9410005.942677.737328.218.306.93130.0195.220.11923.5211519.2802430.782348.98513.111835.862.081.74121.8395.220.11231.361166.380789.32762.82155.31607.510.690.57119.5695.220.1176.561174.130510.95493.80100.54393.260.450.37119.5695.220.1149.561184.370578.05558.47142.36416.120.470.39127.8095.220.1152.441198.97131618.251618.25764.11854.130.970.81180.4195.220.11107.6412018.4602283.832207.16449.381757.781.991.66119.5695.220.11221.5212126.32134064.64064.601558.382506.222.842.37154.4395.220.11315.8412234.91134734.184734.181410.023324.173.773.14135.6195.220.11418.92（續(xù)表）樓層房間面積m2最大冷負(fù)荷時(shí)刻房間最大冷負(fù)荷(含新風(fēng)/全熱)W工程負(fù)荷最大值時(shí)刻(13點(diǎn))的各項(xiàng)負(fù)荷值總冷負(fù)荷(含新風(fēng)/全熱)W室內(nèi)冷負(fù)荷(不含新風(fēng)/全熱)W新風(fēng)冷負(fù)荷W總濕負(fù)荷kg/h新風(fēng)濕負(fù)荷kg/h總冷指標(biāo)(含新風(fēng))W/m2新風(fēng)冷指標(biāo)W/m2總濕指標(biāo)kg/hm2新風(fēng)量m3/h12313.501670.191614.12328.641285.481.461.22119.5695.220.11162.0012442.3135664.945664.941637.094027.854.563.81133.9295.220.11507.6012555.94137293.217293.211966.545326.666.035.03130.3895.220.11671.2812629.903791.543663.84816.732847.113.222.69122.5495.220.11358.801279.6501193.871153.80234.91918.881.040.87119.5695.220.11115.8012833.66134582.144582.141377.003205.143.633.03136.1395.220.11403.9212926.11134039.184039.181552.962486.222.822.35154.7095.220.11313.3213028.64133971.243971.241244.112727.133.092.58138.6695.220.11343.681314.070503.53486.6399.08387.550.440.37119.5695.220.1148.841324.3805

文獻(xiàn)資料檢索的步驟與篩選利用檢索文獻(xiàn)資料信息是一項(xiàng)實(shí)踐性很強(qiáng)的過(guò)程，檢索的一般步驟有以下幾種。在檢索完成之后，才能對(duì)文獻(xiàn)資料進(jìn)行篩選利用。文獻(xiàn)檢索是利用文獻(xiàn)的第一步，如何將其應(yīng)用在畢業(yè)設(shè)計(jì)（論文）課題研究過(guò)程中，對(duì)檢索到的文獻(xiàn)資料進(jìn)行認(rèn)真篩選、消化和吸收是關(guān)鍵。只有經(jīng)過(guò)這個(gè)過(guò)程，才能達(dá)到查閱文獻(xiàn)的真正目的一一一利用文獻(xiàn)1、文獻(xiàn)資料檢索的步驟（1）明確檢索范圍從科研課題研究的中心內(nèi)容和重點(diǎn)出發(fā)，多方面分析課題要求和問(wèn)題實(shí)質(zhì)，一般從三方面考慮：一是區(qū)域界限，要清楚是取得某一一問(wèn)題發(fā)表過(guò)的全部文獻(xiàn)資料，還是要掌握某一地區(qū)、某一國(guó)家對(duì)某一問(wèn)題發(fā)表過(guò)的全部文獻(xiàn)資料；二是時(shí)間范圍，明確是查找某一問(wèn)題在某一年限內(nèi)發(fā)表過(guò)的文獻(xiàn)資料，還是獲取某一。問(wèn)題從有文獻(xiàn)記錄以來(lái)的全部文獻(xiàn)資料；三是專業(yè)范圍，明確要查找什么專業(yè)的科技文獻(xiàn)信息，比如，電子類的還是機(jī)械類的，是理論性的還是應(yīng)用性的等。（2）選擇檢索工具檢索工具有不同的分類方法，按加工文獻(xiàn)和處理信息的手段不同分為手工檢索工具和機(jī)械檢索工具；按照載體形式不同分為書本式檢索工具，磁帶式檢索工具，卡片式、縮微式、膠卷式檢索工具；按照著錄格式的不同可將檢索工具分為以下四種類型：①目錄型檢索工具。目錄型檢索工具是記錄具體出版單位、收藏單位及其他外表特征的工具。它以一個(gè)完。整的出版或收藏單位為著錄單元，一般著錄文獻(xiàn)的名稱、著者、文獻(xiàn)出處等。目錄的種類很多，對(duì)于文獻(xiàn)檢索來(lái)說(shuō)，國(guó)家書目、聯(lián)合目錄、館藏目錄等尤為重要②題錄型檢索工具題錄型檢索工具是以單篇文獻(xiàn)為基本著錄單位來(lái)描述文獻(xiàn)外表特征（如文獻(xiàn)題名、著者姓名、文獻(xiàn)出處等），無(wú)內(nèi)容摘要，是快速報(bào)道文獻(xiàn)信
