1、摘要本設(shè)計為哈爾濱望江集團辦公樓空調(diào)系統(tǒng)工程設(shè)計。哈爾濱望江集團辦公樓屬中小型辦公建筑，本建筑總建筑面積4138m2，空調(diào)面積2833m2。地下一層，地上八層，建筑高度33.9m。全樓冷負荷為191千瓦，全樓采用水冷機組進行集中供給空調(diào)方式。此設(shè)計中的建筑主要房間為辦公室，大多面積較小，且各房間互不連通，應(yīng)使所選空調(diào)系統(tǒng)能夠?qū)崿F(xiàn)對各個房間的獨立控制，綜合考慮各方面因素，確定選用風(fēng)機盤管加新風(fēng)系統(tǒng)。在房間內(nèi)布置吊頂?shù)娘L(fēng)機盤管，采用暗裝的形式。將該集中系統(tǒng)設(shè)為風(fēng)機盤管加獨立新風(fēng)系統(tǒng)，新風(fēng)機組從室外引入新風(fēng)處理到室內(nèi)空氣焓值，不承擔室內(nèi)負荷。風(fēng)機盤管承擔室內(nèi)全部冷負荷及部分的新風(fēng)濕

2、負荷。風(fēng)機盤管加獨立新風(fēng)系統(tǒng)由百葉風(fēng)口下送和側(cè)送。水系統(tǒng)采用閉式雙管同程式，冷水泵三臺，兩用一備；冷卻水泵選三臺，兩用一備。在冷負荷計算的基礎(chǔ)上完成主機和風(fēng)機盤管的選型，并通過風(fēng)量、水量的計算確定風(fēng)管路和水管路的規(guī)格，并校核最不利環(huán)路的阻力和壓頭用以確定新風(fēng)機和水泵。依據(jù)相關(guān)的空調(diào)設(shè)計手冊所提供的參數(shù)，進一步完成新風(fēng)機組、水泵、熱水機組等的選型，從而將其反應(yīng)在圖紙上，最終完成整個空調(diào)系統(tǒng)設(shè)計。關(guān)鍵詞：風(fēng)機盤管加獨立新風(fēng)系統(tǒng)；負荷；管路設(shè)計；制冷機組：冷水機組AbstractThedesignfortheHarbinWangjiangDesignGroupofficebuild
