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。 本次設(shè)計(jì)的建筑對(duì)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(jì)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。該空調(diào)系統(tǒng)的優(yōu)點(diǎn)是占用建筑面積少，可集中供冷和供熱；同時(shí)各末端裝置有獨(dú)立的開關(guān)和調(diào)節(jié)功能，各房間的溫度可獨(dú)自調(diào)節(jié)與控制，并且防止了空氣的交叉感染。新風(fēng)則由新風(fēng)機(jī)組處理后通過獨(dú)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。 摘 要 本設(shè)計(jì)為武漢 某 院門診樓空調(diào)系統(tǒng)設(shè)計(jì)，擬為之設(shè)計(jì)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(gè)房間的吊頂內(nèi)安置一到二個(gè)風(fēng)機(jī)盤管。新風(fēng)機(jī)組吊頂安裝，每一層樓安裝一臺(tái)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?？照{(diào)水系統(tǒng)采 用閉式系統(tǒng) ,因?yàn)樗瞬灰孜廴?,節(jié)省初投資外 ,還具有很大的節(jié)能效果。 本設(shè)計(jì)內(nèi)容包括：空調(diào)冷熱負(fù)荷計(jì)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(jì)算；水力計(jì)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。 airconditioning system and the determination of proof。 selection of airhandling equipment。 airflow calculated。 other equipment of choice。 fan coil and a new air system。 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(jì)算 ............................................................................................. 3 冷負(fù)荷的計(jì)算 ......................................................
