11通風及排煙設計=1\*GB2⑴地下一層的設備機房，為了達到排風的目的應設置軸流風機，而且還要有補風機進行補風；=2\*GB2⑵在公共衛(wèi)生間內(nèi)應該設置吊頂式通風器，為衛(wèi)生間通風換氣；=3\*GB2⑶排煙口平時保持關(guān)閉狀態(tài)，當有火災信號出現(xiàn)時，閥門自行開啟，并連帶排煙風機開啟；=4\*GB2⑷在地上各層的無窗房間和走道的吊頂內(nèi)吊裝排煙風機；=5\*GB2⑸排煙風機入口的前面，安裝排煙防火閥，如果煙氣溫度到了一定值熔斷時，閥門因此而自動關(guān)閉，并連帶將排煙風機關(guān)閉；=6\*GB2⑹排煙設計時，其管道及其他附件等的制作一定選用不會燃燒的材料，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，通常來說在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)的設計和操作；=2\*GB2⑵風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，同時防止和抑制腐蝕空調(diào)風管結(jié)露。12.1.2選用保溫材料因為導熱系數(shù)對保溫材料的熱工性能影響很大，導熱系數(shù)小的保溫材料其保溫效果好。在本次設計中，保溫材料選用離心玻璃棉保溫管材（難燃B1級），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管道的防腐在本設計中，除掉非鍍鋅鋼管表面的銹之后，需要刷防銹漆對其進行保護，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，當其表面有破損時，那么破損處應先刷防銹漆再刷銀粉進行保護。

13消聲減震設計13.1消聲設計空調(diào)系統(tǒng)在運行過程中，通風機、制冷機等會產(chǎn)生的噪聲，此外，設備也會產(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)對噪聲要求高，通風系統(tǒng)的噪聲衰減是不可缺少的。管道系統(tǒng)消聲設計的基本原則如下：=1\*GB2⑴如果直接在機房內(nèi)布置消聲器，應針對其設置檢修門和風管。因為主風道內(nèi)的風速很大，如果消聲器近距離設置在風道附近，那么必會增加噪聲；=2\*GB2⑵消聲器的類型多種多樣，而對于消聲器的選擇，應按照系統(tǒng)需要的消聲量等因素綜合考慮，再根據(jù)技術(shù)經(jīng)濟對比情況去選定；=3\*GB2⑶消聲彎頭等這類消聲器在消聲設計中必不可少，要加以利用。13.2減震設計新風機組，通風機等需吊裝搭設，采用軟管連接機組與風管。為讓其更穩(wěn)固，隔振底座是必不可少的。將水泵，熱泵機組在其上固定。隔振基座質(zhì)量的決定因素取自實驗數(shù)據(jù)。泵底座采用彈簧復合減振器，管路連接靈活。由于熱泵機組重，基礎承載力不小于運行重量的1.5倍。橡膠墊或減震器底座可直接設置在機座下方。

結(jié)論本設計課題是辦公樓內(nèi)空調(diào)系統(tǒng)的設計，建筑內(nèi)主要有辦公室、會議室等功能間。設計主要包括建筑的負荷計算、空調(diào)方案的確定、設備的選型、水系統(tǒng)的設計、水力計算等。綜合運用所學知識，將專業(yè)技能運用到畢業(yè)設計中。學會分析問題、解決問題，提升了專業(yè)素養(yǎng)。按照負荷計算和各種方案的對比，確定建筑室內(nèi)選擇風機盤管加新風系統(tǒng)?？諝馓幚頇C組位于吊頂上。氣流組織選用上送下回的形式，送風口采用方形擴散器和雙層百葉送風口。在水力計算中，選擇假定流速法，并對計算結(jié)果進行了校核。系統(tǒng)在機房內(nèi)定壓通過定壓罐來完成。設計過程中考慮保溫，減震，防煙措施。由于缺少更多的實踐經(jīng)驗，本次的設計有不足之處，日后勤加學習，增強專業(yè)能力。參考文獻趙榮義,錢以明.空氣調(diào)節(jié)[M],第3版.北京:中國建筑工業(yè)出版社,2016.12：345-380唐春成.某超高層辦公樓空調(diào)系統(tǒng)設計[J].制冷,2017,36(01)：46-52孫偉.淺談設計院辦公樓空調(diào)通風系統(tǒng)工程實例[J].中國新技術(shù)新產(chǎn)品,2018,(05)：70-71孫一堅.簡明通風設計手冊[M],第2版.北京:中國建筑工業(yè)出版社,2016.3：105-120何小兵.高檔辦公樓工程項目中的節(jié)能型空調(diào)系統(tǒng)設計[J].建筑施工,2016,38(08)：1102-1104楊迎七.某辦公樓變風量空調(diào)系統(tǒng)控制設計探討[J].建筑熱能通風空調(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)設計[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)設計的幾點體會[J].中國住宅設施,2015,(03)：95-97徐猛.成都某辦公樓空調(diào)系統(tǒng)節(jié)能設計[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)設計案例分析[J].科技創(chuàng)新與應用,2016,(28)：257-258雷會玉,余曉明,朱祥政,張曉.辦公樓輻射空調(diào)系統(tǒng)方案設計[J].制冷技術(shù),2014,34(05)：72-76戴銀寶.上海某辦公樓變風量空調(diào)系統(tǒng)設計[J].建筑技術(shù)開發(fā),2016,43(02)：82-85萬海生.辦公室暖通空調(diào)系統(tǒng)節(jié)能設計[J].中華民居,2014,000(012)：29-30付剛,林佳佳.某辦公樓變風量空調(diào)系統(tǒng)設計及運行分析[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)設計分析[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)方案設計[J].科技風,2014,(20)：141-142唐雄斌.廣東某超高層辦公樓空調(diào)水系統(tǒng)設計[J].制冷與空調(diào)（四川）,2016,30(01)：33-35丁帥,孟慶龍,王博聞.變風量空調(diào)系統(tǒng)送風管道靜壓特性的實驗研究[J].流體機械,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負荷計算樓層房間面積m2最大冷負荷時刻房間最大冷負荷(含新風/全熱)W工程負荷最大值時刻(13點)的各項負荷值總冷負荷(含新風/全熱)W室內(nèi)冷負荷(不含新風/全熱)W新風冷負荷W總濕負荷kg/h新風濕負荷kg/h總冷指標(含新風)W/m2新風冷指標W/m2總濕指標kg/hm2新風量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最大冷負荷時刻房間最大冷負荷(含新風/全熱)W工程負荷最大值時刻(13點)的各項負荷值總冷負荷(含新風/全熱)W室內(nèi)冷負荷(不含新風/全熱)W新風冷負荷W總濕負荷kg/h新風濕負荷kg/h總冷指標(含新風)W/m2新風冷指標W/m2總濕指標kg/hm2新風量m3/h12313.501670.191614.12328.641285.481.461.22119.5695.220.11162.0012442.3135664.945664.941637.094027.854.563.81133.9295.220.11507.6012555.94137293.217293.211966.545326.666.035.03130.3895.220.11671.2812629.903791.543663.84816.732847.113.222.69122.5495.220.11358.801279.6501193.871153.80234.91918.881.040.87119.5695.220.11115.8012833.66134582.144582.141377.003205.143.633.03136.1395.220.11403.9212926.11134039.184039.181552.962486.222.822.35154.7095.220.11313.3213028.64133971.243971.241244.112727.133.092.58138.6695.220.11343.681314.070503.53486.6399.08387.550.440.37119.5695.220.1148.841324.380579.12559.51142.45417.070.470.39127.7495.220.1152.561331201630.491583.68441.021142.651.291.08131.9795.220.11144.0013427.5203607.63605.84985.352620.482.972.48131.0395.220.11330.2413518.5302306.932229.96465.511764.452.001.67120.3495.220.11222.361層小計1272.9113161225.6161225.6140017.81121207.8137.29114.57126.6695.220.1115274.9二層20147.94136191.576191.571626.674564.905.174.31129.1595.220.11575.2820274.68139581.799581.792470.687111.118.056.72128.3095.220.11896.1620337.3134788.014788.011236.273551.744.023.36128.3695.220.11447.6020438134873.234873.231254.833618.404.103.42128.2495.220.11456.0020525.6903178.33071.61625.382446.232.772.31119.5695.220.11308.2820626.5303282.233172.04645.832526.212.862.39119.5695.220.11318.3620726.5503284.73174.44646.322528.122.862.39119.5695.220.11318.6020827.2203367.593254.5466

文獻資料檢索的步驟與篩選利用檢索文獻資料信息是一項實踐性很強的過程，檢索的一般步驟有以下幾種。在檢索完成之后，才能對文獻資料進行篩選利用。文獻檢索是利用文獻的第一步，如何將其應用在畢業(yè)設計（論文）課題研究過程中，對檢索到的文獻資料進行認真篩選、消化和吸收是關(guān)鍵。只有經(jīng)過這個過程，才能達到查閱文獻的真正目的一一一利用文獻1、文獻資料檢索的步驟（1）明確檢索范圍從科研課題研究的中心內(nèi)容和重點出發(fā)，多方面分析課題要求和問題實質(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題發(fā)表過的全部文獻資料，還是要掌握某一地區(qū)、某一國家對某一問題發(fā)表過的全部文獻資料；二是時間范圍，明確是查找某一問題在某一年限內(nèi)發(fā)表過的文獻資料，還是獲取某一。問題從有文獻記錄以來的全部文獻資料；三是專業(yè)范圍，明確要查找什么專業(yè)的科技文獻信息，比如，電子類的還是機械類的，是理論性的還是應用性的等。（2）選擇檢索工具檢索工具有不同的分類方法，按加工文獻和處理信息的手段不同分為手工檢索工具和機械檢索工具；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。它以一個完。整的出版或收藏單位為著錄單元，一般著錄文獻的名稱、著者、文獻出處等。目錄的種類很多，對于文獻檢索來說，國家書目、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為基本著錄單位來描述文獻外表特征（如文獻題名、著者姓名、文獻出處等），無內(nèi)容摘要，是快速報道文獻信
