1、河北工業(yè)大學(xué)城市學(xué)院畢業(yè)設(shè)計(jì)說明書作者:吳俊濤學(xué)號(hào):學(xué)院:能源與環(huán)境工程學(xué)院系(專業(yè)):建筑環(huán)境與設(shè)備工程題目:某辦公建筑中央空調(diào)系統(tǒng)的設(shè)計(jì)指導(dǎo)者:王華軍副教授評(píng)閱者:2011年6月3日廣州民政辦公大樓中央空調(diào)設(shè)計(jì)摘要:本次畢業(yè)設(shè)計(jì)的主要內(nèi)容是對(duì)廣州市民政辦公大樓進(jìn)行中央空調(diào)系統(tǒng)設(shè)計(jì)及通風(fēng)設(shè)計(jì)。該建筑位于廣州市,共有十五層,建筑面積為14556.16平米。一、二層主要是中庭、辦公室,層高為4.8米,三層以上都是辦公室,層高為3.9米。為達(dá)到創(chuàng)造一個(gè)舒適的空調(diào)環(huán)境,根據(jù)房間的功能和設(shè)計(jì)要求,并結(jié)合本辦公樓的建筑特點(diǎn),擬定該建筑采用風(fēng)機(jī)盤加新風(fēng)和全空氣兩種系統(tǒng),水系統(tǒng)
2、采用異程式系統(tǒng)。本次設(shè)計(jì)涉及到空調(diào)系統(tǒng)的劃分,冷負(fù)荷的計(jì)算,空調(diào)設(shè)備的選型,風(fēng)管的水力計(jì)算及布置,管道的消聲、防震,冷凍機(jī)房設(shè)計(jì),水系統(tǒng)的劃分,水管的水力計(jì)算及水管布置,水泵的選擇等。本設(shè)計(jì)中冷卻塔設(shè)置于二樓樓頂,第一二層采用全空氣系統(tǒng),三層至十五層全部采用風(fēng)機(jī)盤管加新風(fēng)系統(tǒng)的空氣處理過程,即將新風(fēng)處理到室內(nèi)空氣的焓值,不承擔(dān)室內(nèi)負(fù)荷,再與經(jīng)由風(fēng)機(jī)盤管處理好的回風(fēng)混合后送入室內(nèi)。冷凍水機(jī)房設(shè)置在地下室,三至十五層每層根據(jù)情況在空調(diào)機(jī)房設(shè)置一臺(tái)意大利克萊門特臥式空調(diào)機(jī)組MFC-U(I)系列的新風(fēng)機(jī)組。本設(shè)計(jì)繪制18張Cad制圖,基本達(dá)到了施工圖的設(shè)計(jì)深度要求。關(guān)鍵詞
