【正文】 h, like the airconditioning system row of wind entire heat recovery, summer uses the heat of condensation the hygienic hot water supply and so on, all is to the system Leng Re recycling use, obviously raised the airconditioning system energy use factor. Third, the existence question and the countermeasure must realize the airconditioning system energy conservation to fall consume, has already met many mature requirements, but simultaneously also has many problems to wait for the solution: 1st, passes the airconditioning system warmly the design management question as mentioned above, the airconditioning system design has the important influence to the airconditioning system energy conservation. Not only however often cannot obtain some design departmention reality and designs the personnel enough to take, to cause the design construction the system at the beginning of to invest in a big way, the movement energy consumption quite is also astonishing, has surpassed the national standards greatly. According to actual, some public building air conditioning energy consumption occupies constructs the total energy consumption 60%.Therefore, we have the necessity to suggest the government related functional departments strengthens to passes the air conditioning design project warmly the management, may entrust the correlation technology department like academic society and so on to carry on the strict examination to the design paper document, to had not achieved the national related energy conservation standard the design forbid strictly the construction construction. 2nd, passes the airconditioning system warmly the movement management question besides the design, we discovered the movement management is also playing the vital role. Some unit39。 management for saving energy Along with the economical rapid development, the energy and the environment question are day by day incisive. May foresee, this kind of condition in also will be able to appear from now on, and will be able to be day by day serious. First, passes the air conditioning domain energy conservation warmly the importance and the feasibility along with society39。參考文獻[1].建筑工程常用數(shù)據(jù)系列手冊編寫組. 暖通空調(diào)常用數(shù)據(jù)手冊[S],北京:中國建筑工業(yè)出版社,2002,50114.[2].北京規(guī)劃委員會、北京市建設委員會. 北京市地方標準公共建筑節(jié)能設計標準,20050701實施.[3].陸亞俊、馬最亮、鄒平華. 暖通空調(diào)[M],中國建筑工業(yè)出版社,2002,1521.[4].萬建武. 空調(diào)工程[M],科學出版社,2005,87.[5].路詩奎、姚壽光. 空調(diào)制冷專業(yè)課程設計指南[M],化學工業(yè)出版社,2005,131.[6].馬最良、姚楊. 民用建筑空調(diào)設計[M],北京:化學工業(yè)出版社,2003,177182.[7].[M],北京:化學工業(yè)出版社2007,10,43.[8].陸耀慶. 實用供熱空調(diào)設計手冊[S],北京:中國建筑工業(yè)出版社,1987.[9].付祥釗、王岳人. 流體輸配管網(wǎng)[M],中國建筑工業(yè)出版社,2001,94.[10].陸亞俊. 暖通空調(diào)[M],中國建筑工業(yè)出版社,2001.[11].[S],中國建筑工業(yè)出版社,1995.[12].《高層民用建筑設計防火規(guī)范》,中國計劃出版社.[13].何耀東、何青. 中央空調(diào)[M],冶金工業(yè)出版社,1998,120.[14].李先洲、李景田. 暖通空調(diào)規(guī)范實施手冊[S],中國建筑工業(yè)出版社,1999,432.[15].尉遲斌. 實用制冷與空調(diào)工程手冊[S],機械工業(yè)出版社,1998,245.外文文獻:About passes the airconditioning system warmlythe energy conservation questionUdonis Haslem abstract: Passes the airconditioning system to occupy the important position warmly in the construction energy conservation, is playing the vital role, the energy conservation technology research development and the utilization is passes the airconditioning system, the building system energy conservation foundation warmly, the government functional departments39。此保溫材料價格低,但很多產(chǎn)品質(zhì)量難于保證,且施工條件差,建筑物裝修過程中易將外覆鋁箔損壞,引起凝結(jié)水滴漏。第八章 管道的保溫及防腐 風管的保溫及防腐 保溫目的、熱量的利用率,避免不必要的冷、熱損失,保證空調(diào)的設計運行參數(shù);,防止其表面溫度可能低于或等于周圍空氣的露點溫度,使表面結(jié)露,加速傳熱;同時可防止結(jié)露對風道的腐蝕。 補水水泵的選擇根據(jù)選型原則,選擇兩臺冷凍水泵(一用一備)。1)水泵流量的確定單臺冷水機組的冷卻水額定水流量為90m 3/h ,即25L/s。4.水泵的出水管上應裝有溫度計和壓力表,以利檢測。根據(jù)《中央空調(diào)設計實訓教程》[1]附錄,選用三臺IS10080125型水泵,其流量為60m 3/h,轉(zhuǎn)速為1450r/min。最不利環(huán)路中并聯(lián)空調(diào)末端裝置中水壓損失最大者是四層右環(huán)路新風機組,它的水壓降=61KPa= H20。2)水泵揚程H 的確定水泵揚程H 按下式計算:H =水泵所承擔的供回水管網(wǎng)最不利環(huán)路為四層右環(huán)路管路。~ m/s范圍確定。由于補水量為整個系統(tǒng)總水量的1%左右,=,故選取北京市萬事泰得電子及能源有限公司生產(chǎn)的分體化系列WT400型高頻電子水垢處理器,技術(shù)參數(shù)如下:處理水量400 m3/h 功率350W 接口方式φ300法蘭尺寸規(guī)格A:1180mm Bφ325 C720mm D160mm 冷卻塔的設計工況和選型冷卻塔冷卻水量可按下式計算: (73) 式中:W——冷卻塔水量m3/h;Q——冷凝器的散熱量,kW;△T——冷卻水進出口溫差(℃),壓縮式制冷機△t=5℃,吸收式制冷機△t=8℃;——水的比熱容,kJ/(kg.℃),(Kg m3/h之間,多選用逆流式。必須有足夠的新水補充。冷卻塔中水與空氣的換熱方式之一是,通過水表面的空氣與水直接接觸,通過接觸傳熱和蒸發(fā)散熱,把水中的熱量傳輸給空氣。ZXLR35型機組主要參數(shù)如下:名義制冷量349KW 蒸發(fā)器進出水溫127℃ 蒸發(fā)器側(cè)冷凍水流量60 m3/h 蒸發(fā)器側(cè)壓力降83kPa 蒸發(fā)器側(cè)進出水管徑100㎜ 冷凝器進出水溫3240℃冷凝器側(cè)冷卻水流量90m3/h 冷凝器側(cè)壓力降82kPa冷凝器側(cè)進出水管徑,125㎜外形尺寸:長3060㎜,寬1735㎜,高1805㎜其所需要的冷凍水量為:[15] m3/h (72)式中:——系統(tǒng)總的制冷量;C——熱水的比熱,2.考慮制冷劑氟利昂對大氣臭氧層的危害和禁用實踐,R11, R12為制冷劑的制冷機應禁止使用。冷水機組根據(jù)冷卻介質(zhì)的不同,又分為水冷式冷水機組和風冷式冷水機組兩大類。 風冷制冷機組年耗電費用=(壓縮機耗電量+風機耗電量)運行時間/年電價 水冷制冷機組年水費=(總循環(huán)水換水次數(shù)+補水量總循環(huán)水量運行時間/年)水價 水冷制冷機組年耗電費用=(壓縮機耗電量+冷卻塔風扇耗電量+冷卻水泵耗電量)運行時間/年電價 本建筑物地處北京市,水源基本充足。 空調(diào)冷凝水管估算表冷負荷Kw≤7~18~100100~176177~598管徑DN2025324050第七章 中央空調(diào)系統(tǒng)冷熱源設計 概述冷熱源是空調(diào)系統(tǒng)的核心部分。 冷凝水系統(tǒng)的確定風機盤管機組在運行時產(chǎn)生的冷凝水,必須及時排走,排放凝結(jié)水的管路的系統(tǒng)設計中,應注意以下幾點:(見文獻[11]P168)1)。根據(jù)流量與管徑確定實際流速ν=G/178。4)根據(jù)各管路的實際情況,列出各管段局部阻力管件名稱,由文獻[9]P74查得各管段的局部阻力部件和局部阻力系數(shù)。同理可查得其他管段的管道尺寸及單位長度摩擦力,見水力計算表。以二層右環(huán)路新風機組為例:主要計算步驟如下:,見下圖,標出管段長度和各送風點的風量。同理可對其他辦公室進行氣流組織計算,散流器具體布置見風管平面圖衛(wèi)生間排風衛(wèi)生間排風換氣次數(shù)為10次/小時,每個衛(wèi)生間選用松下FV—24CHL1C型照明換氣扇一臺,其風量為207m3/h,排風管直徑為100 mm。)189。/4+H178。1. 選用圓形散流器,布置2個散流器,即散流器個數(shù)n=2.2. 選取喉部風速=3m/s,計算得喉部面積=Q/(n)=(32)= ,選用喉部尺寸為φ250的圓形散流器,則喉部實際風速為=[2()178。對室溫允許波動范圍有要求的空調(diào)房間主要采用前三種。 新風機組選型[5]層序號型號風量m3/h 冷量 kw水量L/s水阻力KPa電機轉(zhuǎn)速r/min離心風機數(shù)量外形尺寸LBH mm一層左環(huán)LWHA03333001430113441223475二層左環(huán)LWHA0333300 1430113441223475二層右環(huán)LWHA0232300 1430113441070475三層左環(huán)LWHA03333001430113441223475三層右環(huán)LWHA02323001430113441070475四層左環(huán)LWHA03333001430113441223475四層右環(huán)LWHA02323001430113441070475第五章 風口及氣流組織設計 氣流組織的重要性氣流組織設計是空調(diào)系統(tǒng)設計的一個重要環(huán)節(jié),它直接影響著空調(diào)系統(tǒng)的使用效果。.所以此房間的最小新風量為=305+= 風機盤管選型計算以101辦公室為例:1.計算風機盤管風量:===179。h)],本設計取30;——單位建筑面積每小時所需的最小新風量[m/
