本科論文目錄TOC\o"1-2"\h\z\u2519摘要 ⑶風(fēng)機風(fēng)量大，噪聲大要求衛(wèi)生條件嚴(yán)格的房間，目前較少采用此種方式本設(shè)計為酒店的空調(diào)系統(tǒng)設(shè)計所以對空氣品質(zhì)的要求較高，但是全水系統(tǒng)和冷劑系統(tǒng)卻只能消除室內(nèi)的余熱和余濕[5]，無法達到改良室內(nèi)空氣質(zhì)量的作用，所以在此次的建筑空調(diào)設(shè)計時不予選用。綜上所述，本酒店采用風(fēng)機盤管加新風(fēng)系統(tǒng)，風(fēng)機盤管的新風(fēng)供給方式用單設(shè)新風(fēng)系統(tǒng)獨立供給室內(nèi)。3.3空調(diào)方案的確定該酒店采用風(fēng)機盤管加新風(fēng)系統(tǒng)，占空間少，使用也較靈活。因為該酒店房間類型繁多，各房間冷熱負荷并不相同，可以各房間進行個別的調(diào)節(jié)。每層設(shè)有新風(fēng)機組，可以由同層的新風(fēng)機組送入室內(nèi)。在采用風(fēng)機盤管空調(diào)方式時，如果水管漏水或冷水管產(chǎn)生凝結(jié)水，易對電器設(shè)備產(chǎn)生安全隱患，因此要求確保管道的安裝質(zhì)量。

4系統(tǒng)設(shè)備選型4.1設(shè)計計算4.1．1夏季送風(fēng)狀態(tài)點和送風(fēng)量=1\*GB2⑴新風(fēng)量的確定確定新風(fēng)量的依據(jù)有下列三個因素[6]：①稀釋人群產(chǎn)生的污染物，保證空氣品質(zhì)的要求；②補充局部排風(fēng)量；③保持空調(diào)房間維持正壓。公式為：（4-1）式中：n空調(diào)房間內(nèi)的總?cè)藬?shù)；gw新風(fēng)量標(biāo)準(zhǔn)，即單位時間內(nèi)每人所需的新風(fēng)量，m3/h·人。=2\*GB2⑵夏季送風(fēng)狀態(tài)點和送風(fēng)量的確定[7]綜合考慮能效，選擇處理后的新風(fēng)和風(fēng)機盤管處理過的空氣混合后送入室內(nèi)的方案。新風(fēng)不負擔(dān)室內(nèi)負荷，新風(fēng)處理到室內(nèi)焓值，風(fēng)機盤管處理到點L2，混合到O點一并送入房間，i-d圖上的處理過程如圖4.1所示。圖4.1新風(fēng)與風(fēng)機盤管送風(fēng)混合后送入時的空氣處理過程以7001客房01為例：已知室內(nèi)外參數(shù)tN=25℃，=55%，tW=29.0℃，tWs=26.3℃查得iN=55.5kJ/kg，iw=81.5kJ/kg，由iN=55.5kJ/kg，=95%確定點L1，tL1=20℃，iL1=55.5kJ/kg。在i-d圖中，過N點作ε線與=90%相交，即得送風(fēng)狀態(tài)點O。to=18℃，io=47.5kJ/kg，送風(fēng)溫差=25-18=7℃?？傦L(fēng)量G=Q/(iN-io)=422.5m3/h。換氣次數(shù)定義為房間通風(fēng)量和房間體積的比值，即：（4-2）則7001客房01換氣次數(shù)n=422.5/(22×3.0)=6.4＞5.24，所以符合換氣次數(shù)要求。由于滿足衛(wèi)生的新風(fēng)量Gw1=100m3/h＞總風(fēng)量的10%。則7001客房的最小新風(fēng)量取兩者中的較大值，即Gw=120m3/h。新風(fēng)負荷計算公式：（4-3）則7001客房01的新風(fēng)負荷為Qw=512W風(fēng)機盤管風(fēng)量計算公式：（4-4）則風(fēng)機盤管風(fēng)量為GF=322.5m3/h連接點L1及點O并延長至L2點，使/(Gw/GF),則iL2=io-(iL1-io)GW/GF=46.4kJ/kg則風(fēng)機盤管冷量：（4-5）各房間計算同理。4.2設(shè)備選型4.2．1風(fēng)機盤管的選型根據(jù)風(fēng)機盤管風(fēng)量以及所承擔(dān)的冷量對風(fēng)機盤管進行選型。選用美的品牌臥式暗裝風(fēng)機盤管，型號及性能參數(shù)如表4.1和表4.2所示。表4.1各房間風(fēng)機盤管選型及數(shù)量樓層房間房間面積風(fēng)機盤管數(shù)量1層1001[銀行外]65FP-6821002[銀行內(nèi)]109.01FP-5121003[酒樓大堂]361.82FP-6831004[服務(wù)臺]47.88FP-5111005[財務(wù)室]10.61FP-3411006[商務(wù)中心]8.04FP-3412層2001[餐廳]590.23FP-8592002[廚房]67.95FP-5123層3001[客房]19.03FP-3413002[客房]19.03FP-3413003[客房]19.03FP-3413004[客房]19.03FP-3413005[客房]-3009[客房]23.28FP-3413010[套房]23.28FP-3423011[套房]23.28FP-3423012[套房]15.1FP-3423013[客房]-3019[客房]15.1FP-3413020[客房]20.8FP-3413021[客房]78.6FP-3413022[客房]39.2FP-3413023[客房]39.2FP-3414層-7層4001[客房]-4004[客房]19.03FP-3414005[客房]-4011[客房]23.28FP-3414012[客房]-4019[客房]15.1FP-3414020[客房]20.8FP-3414021[客房]-4027[客房]22.1FP-341表4.2風(fēng)機盤管參數(shù)型號機組形式送風(fēng)量m3/h機外余壓Pa馬達功率W電源V/Ph/Hz制冷量Kw鏈接管道尺寸供回冷凝FP-34臥式暗裝3403047220/1/501.8DN15DN20FP-51臥式暗裝5103062220/1/502.7DN20DN20FP-68臥式暗裝6803072220/1/503.6DN20DN20FP-85臥式暗裝8503080220/1/504.5DN25DN20FP-102臥式暗裝10203092220/1/505.4DN25DN20FP-136臥式暗裝136030115220/1/507.2DN25DN20FP-204臥式暗裝204030155220/1/5010.8DN32DN254.2．2新風(fēng)機的選型新風(fēng)機機組的選型同風(fēng)機盤管，即通過新風(fēng)量及新風(fēng)冷量進行選型，新風(fēng)機組在各個區(qū)域布置一臺，參數(shù)如表4.3所示。表4.3新風(fēng)機組參數(shù)機組編號新風(fēng)量m3/h機外余壓Pa馬達功率W電源V/Ph/Hz制冷量Kw風(fēng)機類型安裝方式臺數(shù)HDK-0330002100.55220/1/5033.6離心式吊裝2HDK-0550002101.039.02HDK-0775003502.047.02

6水系統(tǒng)的設(shè)計6.1水系統(tǒng)方案的確定6.1．1兩管制水系統(tǒng)的特點兩管制水系統(tǒng)是采用同一套供回水管路，冬季供熱水、夏季供冷水。由運行人員依據(jù)需要實行供熱與供冷的轉(zhuǎn)換。系統(tǒng)簡單、一次性投資少，但不能同時供冷水和供熱水。正因為該設(shè)計空調(diào)精度要求不是很高，故采用兩管制[12]。6.1．2閉式系統(tǒng)的特點=1\*GB2⑴水泵揚程僅需克服循環(huán)阻力，與樓層數(shù)無關(guān)僅取決于管路長度和阻力[13]；=2\*GB2⑵循環(huán)水不易受污染，管路腐蝕情況比開式系統(tǒng)好；=3\*GB2⑶需要設(shè)回水池，但要設(shè)一個膨脹水箱。膨脹水箱盡量接至靠近入口的回水干管。6.1．3同程和異程系統(tǒng)的選擇同程式系統(tǒng)供回水干管中的水流方向相同，經(jīng)過每一管路的長度相等，水量分配調(diào)度方便，便于水力平衡，費用高[14]；異程式系統(tǒng)不需設(shè)回程管，管道長度較短，管路簡單，費用低，水力平衡較困難。本設(shè)計客房區(qū)域選用同程式系統(tǒng)，其它采用異程系統(tǒng)。6.1．4一次泵變流量系統(tǒng)的選擇依據(jù)=1\*GB2⑴定水量系統(tǒng)中循環(huán)水量為定值，夏季和冬季分別采用兩個不同的定水量，一旦負荷變化，調(diào)節(jié)制冷量和供、回水溫度[15]。定水量系統(tǒng)簡單，不需要變水量定壓控制。通過閥門改變表冷器的水量，用戶之間不相互干擾，運行較穩(wěn)定[16]。缺點是水量均按最大負荷確定的，且最大負荷出現(xiàn)時間很短，即使在最大負荷時，各朝向的峰值也不會在同一時間內(nèi)出現(xiàn)，因此水泵無效能耗很大。=2\*GB2⑵變流量系統(tǒng)保持供水溫度在一定范圍內(nèi)，一旦負荷變化，需改變供水量。變流量系統(tǒng)的負荷越少水泵能耗越少，所以水泵運行能量可大為降低，經(jīng)濟性較高。但需要利用供、回水壓差進行流量的控制，自控系統(tǒng)復(fù)雜。=3\*GB2⑶本次設(shè)計采用一次泵變流量系統(tǒng)，其原理如下：在系統(tǒng)處于設(shè)計狀態(tài)下，所有設(shè)備都滿負荷運行，壓差旁通閥開度為零，這時壓差控制器兩端接口處的壓力差為零。當(dāng)末端負荷變小時，末端的兩通閥關(guān)小，使末端設(shè)備中冷凍水的流量按比例減少，從而使被調(diào)參數(shù)保持在設(shè)計值范圍內(nèi)。=4\*GB2⑷二次泵變流量系統(tǒng)雖然能節(jié)省冷凍水泵的耗電量，但經(jīng)濟性較差，自控要求比較高，所用空間也較大。6.1．5水系統(tǒng)方案的確定本設(shè)計采用兩管制、閉式、一次泵變流量系統(tǒng)，各層水管同程或異程布置。為保證負荷變化時系統(tǒng)能有效、可靠節(jié)能的運行，設(shè)置兩臺冷凍水泵，一用一備；風(fēng)機盤管供回水管上均設(shè)有調(diào)節(jié)閥，依據(jù)負荷的變化靈活的調(diào)節(jié)[17]。為防止管網(wǎng)因雜質(zhì)和結(jié)垢而造成水路堵塞影響使用，在冷凍回水口上設(shè)Y型過濾器。冷凍水管采用焊接鋼管，冷凝管采用鍍鋅鋼管，管道保溫前刷兩道防銹底漆。6.2供回水管路設(shè)計計算步驟設(shè)計計算步驟如下：=1\*GB2⑴繪制軸測圖，并對管段進行編號同時標(biāo)注出長度和風(fēng)量。=2\*GB2⑵根據(jù)各房間冷負荷，計算管段流量：（6-1）=3\*GB2⑶管徑的確定根據(jù)假定的流速和確定的流量計算出管徑：（6-2）再根據(jù)給定的管徑規(guī)格選定管徑，由確定的管徑計算出管內(nèi)的實際流速：（6-3）=4\*GB2⑷阻力計算①沿程阻力計算（6-4）②局部阻力計算（6-5）③總阻力（6-6）6.3供回水水力計算供回水水力計算利用假定流速法，本次設(shè)計以四層為例進行設(shè)計計算：水力計算結(jié)果如表6.1和表6.2所示，各樓層的水力計算表如附錄2所示。表6.1分支1最不利路徑水力計算表最不利阻力74227Pa最不利環(huán)路立管1樓層1編號Q(W)G(kg/h)L(m)D(mm)υ(m/s)R(Pa/m)ΣξΔPy(Pa)ΔPj(Pa)ΔP(Pa)不平衡率V25800.8108.451.554247810200.00%V25800.8108.451.554247810200.00%E1339005830.81.6500.73159.342.225658132583880.00%F43.12500.77175.870.1548305780.00%FG123750064501.75500.81193.210.1339333720.00%FG11402006914.43.01500.87220.720.1664387020.00%FG104200072242.02500.91240.070.1486415270.00%FG9438007533.62.78500.95260.210.1723457680.00%FG8456007843.21.01500.99281.170.1283493320.00%FG7474008152.82.02650.6284.730.1171191900.00%FG6492008462.44.83650.6590.940.1439214600.00%FG55100087720.35650.6797.370.13423570.00%FG4528009081.62.81650.69104.020.1293243170.00%FG37980013725.63.55651.05229.540.1815558700.00%FG28160014035.20.53651.07239.631.51278659920.00%F20.79800.8108.451.5864785640.00%F43.39500.77175.870.1597306270.00%FH123750064501.78500.81193.210.1343333760.00%FH11402006914.42.71500.87220.720.1598386360.00%FH104200072242.3500.91240.070.1552415940.00%FH9438007533.62.8500.95260.210.1729457740.00%FH8456007843.20.73500.99281.170.1205492540.00%FH7474008152.81.99650.6284.730.1169191880.00%FH6492008462.45.13650.6590.940.1467214870.00%FH55100087720.33650.6797.370.13223540.00%FH4528009081.62.54650.69104.020.1264242880.00%FH37980013725.63.83651.05229.540.1879559340.00%FH28160014035.20.25651.07239.63361172917900.00%F20.64800.8108.450700700.00%表6.2立管1樓層四水力計算表最不利阻力72186Pa最有利阻力32701Pa樓層內(nèi)不平衡率54.70%編號Q(W)G(kg/h)L(m)D(mm)υ(m/s)R(Pa/m)ΣξΔPy(Pa)ΔPj(Pa)ΔP(Pa)不平衡率F20.79800.8108.451.5864785640.00%FG28160014035.20.53651.07239.631.51278659920.00%FG37980013725.63.55651.05229.540.1815558700.00%FG4528009081.62.81650.69104.020.1293243170.00%FG55100087720.35650.6797.370.13423570.00%FG6492008462.44.83650.6590.940.1439214600.00%FG7474008152.82.02650.6284.730.1171191900.00%FG8456007843.21.01500.99281.170.1283493320.00%FG9438007533.62.78500.95260.210.1723457680.00%FG104200072242.02500.91240.070.1486415270.00%FG11402006914.43.01500.87220.720.1664387020.00%FG123750064501.75500.81193.210.1339333720.00%F43.12500.77175.870.1548305780.00%FG142700046447.47500.58103.421.5772257102931.60%F42.89500.5590.771.62632385010.00%FG1672001238.40.06250.56218.721.51323424712.90%FG175400928.82.95250.42127.550.137693850.00%FG183600619.22.61200.5257.150.1672126850.00%FG191800030962.85400.65177.141.55053188230.00%FG20162002786.41.81400.59145.090.1263172800.00%FG21144002476.82.91320.72260.160.1756267820.00%FG22126002167.22.41320.63201.90.1487205060.00%FG23108001857.62.43320.54150.890.1367143820.00%FG24900015481.35320.45107.160.1144101540.00%FG2572001238.41.2250.56218.720.1262162780.00%FG265400928.83.21250.42127.551.64091405500.00%FG273600619.21.85200.5257.151.54751856600.00%FG2845007743250.3590.931.52739136452.70%F20.64800.8108.450700700.00%FH28160014035.20.25651.07239.63361172917900.00%FH37980013725.63.83651.05229.540.1879559340.00%FH4528009081.62.54650.69104.020.1264242880.00%FH55100087720.33650.6797.370.13223540.00%FH6492008462.45.13650.6590.940.1467214870.00%FH7474008152.81.99650.6284.730.1169191880.00%FH8456007843.20.73500.99281.170.1205492540.00%FH9438007533.62.8500.95260.210.1729457740.00%FH104200072242.3500.91240.070.1552415940.00%FH11402006914.42.71500.872

結(jié)論本設(shè)計通過空調(diào)冷熱負荷的計算、空調(diào)系統(tǒng)的劃分與系統(tǒng)方案的確定、設(shè)備選型、風(fēng)系統(tǒng)設(shè)計計算、水系統(tǒng)設(shè)計計算后經(jīng)比較得出結(jié)論：因該設(shè)計的建筑類型為酒店，所以對內(nèi)部的空氣品質(zhì)要求較高，但是全水系統(tǒng)和冷劑系統(tǒng)卻只能消除室內(nèi)的余熱和余濕，無法達到改良室內(nèi)空氣質(zhì)量的作用，所以在此次的建筑空調(diào)設(shè)計時不予選用。經(jīng)系統(tǒng)方案的比較得出本酒店適合采用風(fēng)機盤管加新風(fēng)系統(tǒng)的空調(diào)系統(tǒng)形式。風(fēng)管選用矩形風(fēng)管，易于加工，安裝方便，具有一定的機械強度和良好的防火性能且氣流阻力較小。水系統(tǒng)采用兩管制、閉式、一次泵變流量系統(tǒng)，水泵的選擇首先要滿足最高運行工況的流量和揚程，使水泵的工作狀態(tài)點處于高效率范圍，并保留一定的富余量，本次設(shè)計水泵采用一用一備，總共兩臺，選用臥式離心變頻冷凍泵。進行水泵的配管布置時安裝軟性接管，有利于降噪，出口裝止回閥并在水泵的吸入管和壓出管上應(yīng)分別設(shè)進口閥和出口閥，便于水泵排空系統(tǒng)內(nèi)的存水，方便檢修。本設(shè)計采用膨脹水箱定壓，壓力穩(wěn)定、系統(tǒng)簡單，基本不用管理。這次設(shè)計的系統(tǒng)選定僅適用于酒店類建筑，設(shè)備選型及具體的機組型號僅適用于同樣負荷下的空調(diào)系統(tǒng)，由于缺少更多的實踐經(jīng)驗，本次的設(shè)計有不足之處，日后勤加學(xué)習(xí)，爭取更加完善。
