通(tong)常來講，居住(zhu)在室內的(de)(de)人每小時需求30m3新鮮空氣或居所每小時換(huan)氣1次(ci)，這(zhe)(zhe)(zhe)是(shi)(shi)(shi)基本的(de)(de)要(yao)求，也(ye)可說是(shi)(shi)(shi)衛(wei)生通(tong)風(feng)。開窗(chuang)通(tong)風(feng)是(shi)(shi)(shi)人們習以(yi)為常的(de)(de)事(shi)情，但它(ta)的(de)(de)換(huan)氣次(ci)數能(neng)達到每小時10-30次(ci)，這(zhe)(zhe)(zhe)對建筑節能(neng)極為不利(li)。在西方發(fa)達 ，人們很早就(jiu)認識(shi)到了這(zhe)(zhe)(zhe)個問(wen)題(ti)(ti)，并采用了很好的(de)(de)辦法(fa)來解決這(zhe)(zhe)(zhe)個問(wen)題(ti)(ti)，那就(jiu)是(shi)(shi)(shi)通(tong)風(feng)器的(de)(de)使用。

對(dui)很(hen)多人來(lai)說(shuo)，建(jian)筑(zhu)(zhu)用無(wu)動力(li)通(tong)(tong)(tong)(tong)風(feng)(feng)(feng)器還是(shi)個(ge)陌生(sheng)的(de)概念，甚至很(hen)多建(jian)筑(zhu)(zhu)行(xing)業內的(de)人士(shi)對(dui)此也鮮有耳(er)聞。通(tong)(tong)(tong)(tong)風(feng)(feng)(feng)器就(jiu)是(shi)窗體或者幕(mu)墻系(xi)統(tong)上安裝一個(ge)通(tong)(tong)(tong)(tong)風(feng)(feng)(feng)裝置，來(lai)保持(chi)建(jian)筑(zhu)(zhu)內外的(de)空氣流通(tong)(tong)(tong)(tong)，有自然通(tong)(tong)(tong)(tong)風(feng)(feng)(feng)和(he)機(ji)械通(tong)(tong)(tong)(tong)風(feng)(feng)(feng)兩種形式。目前通(tong)(tong)(tong)(tong)風(feng)(feng)(feng)器的(de)發展，在國內還處于起步階段，但是(shi)像萬科等少數大品牌的(de)房(fang)產企(qi)業已經極力(li)推(tui)廣(guang)建(jian)筑(zhu)(zhu)通(tong)(tong)(tong)(tong)風(feng)(feng)(feng)系(xi)統(tong)，并將它作為一個(ge)新的(de)賣點。
