1、(20__屆)本科畢業(yè)設(shè)計(jì)上海市國湖寫字樓空調(diào)設(shè)計(jì)84摘要本次畢業(yè)設(shè)計(jì)題目為上海市國湖寫字樓空調(diào)設(shè)計(jì),辦公樓總建筑面積為10500㎡,地下一層,為地下車庫,有通風(fēng)要求。地上10層,一層為大堂和商業(yè)用房;二層為員工活動室;三至九層為辦公室、會客室、資料室等;十層為會議室。根據(jù)本建筑的功能特點(diǎn),選取了全空氣系統(tǒng)和風(fēng)機(jī)盤管加獨(dú)立新風(fēng)系統(tǒng)空調(diào)方式,對于商場等大空間采用全空氣系統(tǒng),客房等較小的空間就用風(fēng)機(jī)盤管加獨(dú)立新風(fēng)系統(tǒng)。風(fēng)機(jī)盤管加獨(dú)立新風(fēng)系的空調(diào)方式是由風(fēng)機(jī)盤管承擔(dān)室內(nèi)所有冷負(fù)荷,而新風(fēng)負(fù)荷由各層新風(fēng)機(jī)組來承擔(dān),新風(fēng)通過新風(fēng)機(jī)組處理到與室內(nèi)等焓值
2、的狀態(tài),直接送入房間。冷水機(jī)組布置在地下一層機(jī)房內(nèi)。該設(shè)計(jì)詳細(xì)介紹了系統(tǒng)方案的確定和該系統(tǒng)的冷負(fù)荷的計(jì)算、氣流組織的校核、設(shè)備的選型、風(fēng)系統(tǒng)、水系統(tǒng)的水力計(jì)算及冷水機(jī)房的設(shè)計(jì)和設(shè)備的布置。關(guān)鍵字:全空氣系統(tǒng);風(fēng)機(jī)盤管加新風(fēng)系統(tǒng);水力平衡。84AbstractThetopicforthegraduationdesignisaboutair-conditioningdesignoftheshanghaiguohuOfficeBuilding.Theconstructionareaisabout10500squaremeters.Thisisat
