簡述新風系統的組成及工作原理

新風系統的組成及工作原理

新(xin)風(feng)系(xi)統由風(feng)機、風(feng)道(dao)、排(pai)風(feng)口(kou)、進風(feng)口(kou)及其它附件組(zu)成。根據房間壓力(li)場(chang)的不同，分正(zheng)壓式(shi)、負(fu)壓式(shi)新(xin)風(feng)系(xi)統和雙向熱回(hui)收式(shi)新(xin)風(feng)系(xi)統，它們的工(gong)作原(yuan)理有所不同。

正(zheng)壓式新風系統是通過風機運轉，把室外新鮮空(kong)(kong)(kong)氣(qi)經(jing)過過濾后從(cong)進風口(kou)(kou)送入房(fang)間(jian)的活動區域(yu)，在(zai)室內(nei)形成(cheng)正(zheng)壓，原室內(nei)的污濁空(kong)(kong)(kong)氣(qi)在(zai)壓力場作(zuo)用下，通過排(pai)風口(kou)(kou)、排(pai)風道排(pai)至室外，完成(cheng)換(huan)氣(qi)。負壓式新風系統是通過風機將室內(nei)混(hun)濁空(kong)(kong)(kong)氣(qi)抽出，使房(fang)間(jian)內(nei)形成(cheng)負壓，室外空(kong)(kong)(kong)氣(qi)從(cong)門(men)、窗等縫隙或者負壓的進風口(kou)(kou)流(liu)入室內(nei)，完成(cheng)換(huan)氣(qi)需要(yao)。

雙向熱(re)回收(shou)(shou)式(shi)新風(feng)(feng)系(xi)統又稱為全(quan)(quan)(quan)熱(re)交(jiao)(jiao)換(huan)(huan)新風(feng)(feng)系(xi)統，在(zai)全(quan)(quan)(quan)熱(re)交(jiao)(jiao)換(huan)(huan)器內(nei)部設(she)有進排(pai)風(feng)(feng)機、全(quan)(quan)(quan)熱(re)交(jiao)(jiao)換(huan)(huan)芯。室(shi)外(wai)新鮮空(kong)氣(qi)(qi)首(shou)先經過過濾，進入全(quan)(quan)(quan)熱(re)交(jiao)(jiao)換(huan)(huan)器，然后(hou)通(tong)過風(feng)(feng)管及送風(feng)(feng)口(kou)送向各個區域；室(shi)內(nei)渾濁空(kong)氣(qi)(qi)通(tong)過室(shi)內(nei)排(pai)風(feng)(feng)口(kou)，經過濾后(hou)進入全(quan)(quan)(quan)熱(re)交(jiao)(jiao)換(huan)(huan)器，然后(hou)集中(zhong)排(pai)到(dao)室(shi)外(wai)；新鮮空(kong)氣(qi)(qi)和渾濁空(kong)氣(qi)(qi)在(zai)全(quan)(quan)(quan)熱(re)交(jiao)(jiao)換(huan)(huan)芯處完成(cheng)溫濕度交(jiao)(jiao)換(huan)(huan)，回收(shou)(shou)排(pai)到(dao)室(shi)外(wai)渾濁空(kong)氣(qi)(qi)中(zhong)的大部分能量，是一種高效、環保(bao)、節能的全(quan)(quan)(quan)方位換(huan)(huan)氣(qi)(qi)系(xi)統。

新風系統的分類

1、新(xin)風(feng)系(xi)(xi)統(tong)(tong)按送風(feng)方式(shi)分(fen)類分(fen)為：單向(xiang)流新(xin)風(feng)系(xi)(xi)統(tong)(tong)，雙向(xiang)流新(xin)風(feng)系(xi)(xi)統(tong)(tong)，全熱(re)交換新(xin)風(feng)系(xi)(xi)統(tong)(tong)，地送風(feng)系(xi)(xi)統(tong)(tong)。

2、新(xin)風(feng)系(xi)統(tong)按(an)安裝方(fang)式分類分為(wei)：中央管道新(xin)風(feng)系(xi)統(tong)和單體新(xin)風(feng)系(xi)統(tong)。

新風(feng)系統(tong)的組成(cheng)及工作(zuo)原(yuan)理

新風(feng)系(xi)統由風(feng)機、風(feng)道、排(pai)風(feng)口、進風(feng)口及其它附件(jian)組成。根據(ju)房間(jian)壓(ya)力場的(de)不同(tong)，分正壓(ya)式、負壓(ya)式新風(feng)系(xi)統和(he)雙向熱回收(shou)式新風(feng)系(xi)統，它們的(de)工作(zuo)原理有所不同(tong)。

正(zheng)壓式(shi)(shi)新(xin)(xin)風(feng)(feng)系統是通(tong)(tong)過(guo)風(feng)(feng)機運(yun)轉，把室(shi)(shi)外(wai)新(xin)(xin)鮮空(kong)氣經(jing)過(guo)過(guo)濾(lv)后從(cong)進(jin)風(feng)(feng)口(kou)送入(ru)房間的(de)活動區域，在室(shi)(shi)內形(xing)成(cheng)正(zheng)壓，原(yuan)室(shi)(shi)內的(de)污濁(zhuo)空(kong)氣在壓力(li)場(chang)作用(yong)下(xia)，通(tong)(tong)過(guo)排風(feng)(feng)口(kou)、排風(feng)(feng)道排至室(shi)(shi)外(wai)，完成(cheng)換(huan)氣。負壓式(shi)(shi)新(xin)(xin)風(feng)(feng)系統是通(tong)(tong)過(guo)風(feng)(feng)機將室(shi)(shi)內混濁(zhuo)空(kong)氣抽出，使房間內形(xing)成(cheng)負壓，室(shi)(shi)外(wai)空(kong)氣從(cong)門、窗等縫隙或(huo)者負壓的(de)進(jin)風(feng)(feng)口(kou)流入(ru)室(shi)(shi)內，完成(cheng)換(huan)氣需要。
