格柵風(feng)(feng)口能提高室(shi)(shi)內空(kong)(kong)氣(qi)(qi)品質(zhi)、降(jiang)低建筑(zhu)(zhu)能耗，以及進行大空(kong)(kong)間局部熱(re)濕(shi)環境(jing)的控(kong)制，逐步成為當(dang)今辦(ban)公(gong)樓(lou)(lou)建筑(zhu)(zhu)空(kong)(kong)調(diao)發展(zhan)的重要方(fang)向(xiang)，同時也對(dui)辦(ban)公(gong)樓(lou)(lou)傳統(tong)(tong)空(kong)(kong)調(diao)系統(tong)(tong)的設計提出新的挑戰。傳統(tong)(tong)的辦(ban)公(gong)樓(lou)(lou)中央空(kong)(kong)調(diao)格柵風(feng)(feng)口系統(tong)(tong)為：風(feng)(feng)機盤管加新風(feng)(feng)機組(zu)空(kong)(kong)調(diao)系統(tong)(tong)，集中式定(ding)風(feng)(feng)量空(kong)(kong)調(diao)系統(tong)(tong)，以及變風(feng)(feng)量空(kong)(kong)調(diao)系統(tong)(tong)。這(zhe)些系統(tong)(tong)通常采(cai)用(yong)頂棚送風(feng)(feng)（上送風(feng)(feng)）的空(kong)(kong)調(diao)方(fang)式，它強調(diao)送風(feng)(feng)氣(qi)(qi)流與室(shi)(shi)內空(kong)(kong)氣(qi)(qi)的充分混(hun)合(he)，由(you)吊(diao)頂送出的空(kong)(kong)氣(qi)(qi)吸(xi)收(shou)室(shi)(shi)內產生的全部余熱(re)、余濕(shi)并稀釋污染物(wu)，這(zhe)樣使(shi)室(shi)(shi)內所有空(kong)(kong)間的溫濕(shi)度基本一(yi)致。此(ci)種控(kong)制方(fang)式不能很好地滿足同一(yi)使(shi)用(yong)空(kong)(kong)間中不同使(shi)用(yong)者對(dui)溫度和通風(feng)(feng)的不同要求。而且，一(yi)旦系統(tong)(tong)安裝(zhuang)后，就不便于以后根據需要更改風(feng)(feng)口的位置。
