【正文】 摘 要 本設(shè)計為武漢 某 院門診樓空調(diào)系統(tǒng)設(shè)計，擬為之設(shè)計合理的中央空調(diào)系統(tǒng)，為室內(nèi)人員提供舒適的工作環(huán)境。 系統(tǒng)主要采用風(fēng)機(jī)盤管承擔(dān)空調(diào)房間的冷負(fù)荷與熱負(fù)荷，每個房間的吊頂內(nèi)安置一到二個風(fēng)機(jī)盤管。新風(fēng)則由新風(fēng)機(jī)組處理后通過獨立的新風(fēng)管道先送入風(fēng)機(jī)盤管，再與回風(fēng)混合一起送入房間。新風(fēng)機(jī)組吊頂安裝，每一層樓安裝一臺新風(fēng)機(jī)組負(fù)擔(dān)該層所有空調(diào)房間的新風(fēng)負(fù)荷。該空調(diào)系統(tǒng)的優(yōu)點是占用建筑面積少，可集中供冷和供熱；同時各末端裝置有獨立的開關(guān)和調(diào)節(jié)功能，各房間的溫度可獨自調(diào)節(jié)與控制，并且防止了空氣的交叉感染?？照{(diào)水系統(tǒng)采 用閉式系統(tǒng) ,因為它除了不易污染 ,節(jié)省初投資外 ,還具有很大的節(jié)能效果。 本次設(shè)計的建筑對象位于武漢市 ,該建筑的樓層結(jié)構(gòu)為地上八層，總建筑面積約為 6500 m2，其中設(shè)計空調(diào)面積 4500m2，空調(diào)總冷負(fù)荷為 660kw，單位面積冷指標(biāo)為 146W，單位面積熱指標(biāo)為 110W。 本設(shè)計內(nèi)容包括：空調(diào)冷熱負(fù)荷計算；空調(diào)系統(tǒng)的確定及論證；送風(fēng)狀態(tài)參數(shù)及送風(fēng)量的確定；空氣處理設(shè)備的選型；冷熱源的選擇及設(shè)備選型；氣流組織計算；水力計算；其他設(shè)備的選擇；保溫與防腐以及減振和消聲等內(nèi)容。 關(guān)鍵字： 空調(diào)系統(tǒng)； 風(fēng)機(jī)盤管加新風(fēng)系統(tǒng)； 性能比較； 末 端設(shè)備 ABSTRACT This airconditioning systems design for the Wuhan Tumor Hospital outpatient floor design it to be a reasonable central air conditioning syste m for indoor staff provide a fortable working environment. Fancoil system is mainly used airconditioned rooms bear the cooling load and the heat load, the ceiling of each room placement within 1 2 fancoils. The new wind of fresh air through independent channels into the first fancoil, and then mixed together with return air into the room. New wind generating units installed on ceiling, each floor to install a new air unit of the burden of all airconditioned rooms in the new wind load. The airconditioning system has the advantage of occupying less floor space, cooling and heating can be concentrated at the same time, the terminal device and a separate regulatory function switch, the room temperature alone can regulate and control, and prevent cross infection of the air. Airconditioning system uses closedwater systems, not because it apar t from pollution, save initial investment, but also has great energysaving effect. Thedesign of the building object is located inWuhanCity,basement floor eight layers with a total construction area of about 6500, the total airconditioning cooling load fo r the 660KW, per unitarea of cold indicators 146W, unit area heat index of 110W. The design elements include: hot and cold airconditioning load calculation。 airconditioning system and the determination of proof。 air supply and air supply parameters of the determination。 selection of airhandling equipment。 cold and heat source of choice and selection of equipment。 airflow calculated。 hydraulic calculation。 other equipment of choice。 thermal insulation and anticorrosion and vibration and noise reduction, and other content. KEYWORDS: airconditioning systems。 fan coil and a new air system。 performance parison。 Terminal equipment . 目 錄 前 言 ........................................................................................................ 1 1 原始資料 ............................................................................................. 3 工程概況 ............................................................................................ 3 氣象資料 ............................................................................................ 3 2 負(fù)荷計算 ............................................................................................. 3 冷負(fù)荷的計算 ................................................................................... 3 冷負(fù)荷的計算方法 ....................................................................... 4 空調(diào)冷負(fù)荷計算 ............................................................................. 4 濕負(fù)荷計算 ....................................................................................... 8 熱負(fù)荷計算 ....................................................................................... 8 各房間負(fù)荷的計算 ........................................................................... 9 101 房間冷負(fù)荷計算 ..................................................................... 9 102 房間熱負(fù)荷的計算 ............................................................... 11 102 房間濕負(fù)荷的計算 ............................................................... 12 3 空調(diào)系統(tǒng)的確定及論證 ................................................................. 13 空調(diào)系統(tǒng)的確定 ............................................................................. 13 空調(diào)系統(tǒng)的分類 .......................................................................... 13 空調(diào)水系統(tǒng)的分類 ..................................................................... 13 本次設(shè)計的方案 ............................................................................. 16 風(fēng)機(jī)盤管加新風(fēng)系統(tǒng) ................................................................. 16 方案比較論證 ................................................................................. 16 風(fēng)機(jī)盤管加新風(fēng)與空氣 水誘導(dǎo)器系統(tǒng)的比較 ....................... 16 風(fēng)機(jī)盤管與新風(fēng)連接方式的比較 ............................................. 17 結(jié)論 .................................................................................................. 18 4 送風(fēng)狀態(tài)參數(shù)及送風(fēng)量的確定 ................................................... 18 新風(fēng)量規(guī)定 ..................................................................................... 18 風(fēng)機(jī)盤管系統(tǒng)風(fēng)量的計算 ............................................................. 19 風(fēng)機(jī)盤管的夏季處理過程 ......................................................... 19 風(fēng)機(jī)盤管的冬季處理過程。 ..................................................... 20 5 空氣處理設(shè)備的選型 ..................................................................... 21 風(fēng)機(jī)盤管的選型 ............................................................................. 21 新風(fēng)機(jī)組的選型 .......................................................................... 26 6 冷熱源的選擇及設(shè)備選型 ............................................................ 28 冷熱源的選擇 ................................................................................. 28 冷源 . ............................................................................................. 28 機(jī)組選型 .......................................................................................... 29 7 氣流組織計算 .........................................................................
