1、杭州市人民政府辦公樓空調(diào)工程設(shè)計(jì)摘要本設(shè)計(jì)為杭州市人民政府辦公大樓空調(diào)工程設(shè)計(jì),大樓共十一層,總建筑面積16937.2㎡,包括一樓大廳,辦公室,娛樂室,結(jié)算室,調(diào)解室,信訪室等功能間。通過方案比較,在負(fù)荷計(jì)算的基礎(chǔ)上,采用了風(fēng)機(jī)盤管加新風(fēng)和全空氣兩種空調(diào)系統(tǒng)形式。風(fēng)機(jī)盤管為臥式暗裝,新風(fēng)不承擔(dān)室內(nèi)負(fù)荷,室內(nèi)回風(fēng)與新風(fēng)混合后經(jīng)雙層百葉風(fēng)口送出;全空氣系統(tǒng)為一次回風(fēng)系統(tǒng),一樓大廳采用側(cè)送風(fēng)方式,其余全空氣送風(fēng)采用吊頂送風(fēng)方式,吊頂回風(fēng),送風(fēng)口均為雙層百葉風(fēng)口,回風(fēng)口均為單層百葉風(fēng)口。新風(fēng)從墻洞引入,再由新風(fēng)機(jī)組集中處理供應(yīng)。因杭州市無城市熱力管網(wǎng),故系統(tǒng)冷熱
2、源采用直燃式溴化鋰?yán)錈崴畽C(jī)組,采用了閉式水平異程,豎直同程兩管制定流量水系統(tǒng)。用假定流速法對(duì)風(fēng)管及水管進(jìn)行水力計(jì)算,并進(jìn)行校核。在滿足冷量,晝量滿風(fēng)量的前提下進(jìn)行設(shè)備選型。冷卻塔選用圓形逆式冷卻塔,置于大樓樓頂。系統(tǒng)定壓采用膨脹水箱定壓方式,置于大樓樓頂。水管用泡沫橡塑保溫,風(fēng)管采用離心玻璃棉。設(shè)計(jì)工程中慮了消聲、減振和防火排煙的措施。整個(gè)系統(tǒng)在設(shè)計(jì)過程中,以達(dá)到高效、節(jié)能、環(huán)保的目的。嚴(yán)格遵循空調(diào)規(guī)范的規(guī)定,參考相關(guān)資料,對(duì)系統(tǒng)的各個(gè)環(huán)節(jié)進(jìn)行綜合性的考慮,從而提供一個(gè)實(shí)用的空調(diào)系統(tǒng)設(shè)計(jì)關(guān)鍵詞:空調(diào),風(fēng)機(jī)盤管加新風(fēng)系統(tǒng),全空氣系統(tǒng),新風(fēng)THEAIRCON
