全(quan)(quan)熱(re)(re)(re)(re)交(jiao)換器通(tong)(tong)常是(shi)指一種含有全(quan)(quan)熱(re)(re)(re)(re)換芯體的(de)(de)新(xin)(xin)風(feng)(feng)(feng)、排(pai)(pai)風(feng)(feng)(feng)換氣(qi)(qi)設備。 在小型家用(yong)空(kong)(kong)調(diao)(diao)(diao)(diao)或VRV空(kong)(kong)調(diao)(diao)(diao)(diao)系(xi)統(tong)(tong)中(zhong)，因不(bu)帶新(xin)(xin)風(feng)(feng)(feng)，室(shi)內空(kong)(kong)氣(qi)(qi)品(pin)質(zhi)較差．需要在系(xi)統(tong)(tong)中(zhong)采用(yong)熱(re)(re)(re)(re)回收裝(zhuang)置(zhi)。全(quan)(quan)熱(re)(re)(re)(re)交(jiao)換器是(shi)一種節(jie)(jie)(jie)能(neng)的(de)(de)熱(re)(re)(re)(re)回收裝(zhuang)置(zhi)，通(tong)(tong)過回收排(pai)(pai)氣(qi)(qi)中(zhong)的(de)(de)余熱(re)(re)(re)(re)對引(yin)入空(kong)(kong)調(diao)(diao)(diao)(diao)系(xi)統(tong)(tong)的(de)(de)新(xin)(xin)風(feng)(feng)(feng)進行(xing)預熱(re)(re)(re)(re)或預冷，在新(xin)(xin)風(feng)(feng)(feng)進入室(shi)內或空(kong)(kong)調(diao)(diao)(diao)(diao)機組的(de)(de)表冷器進行(xing)熱(re)(re)(re)(re)濕(shi)處(chu)理之前，降低(增加)新(xin)(xin)風(feng)(feng)(feng)焓(han)值。有效(xiao)降低空(kong)(kong)調(diao)(diao)(diao)(diao)系(xi)統(tong)(tong)負荷，節(jie)(jie)(jie)省空(kong)(kong)調(diao)(diao)(diao)(diao)系(xi)統(tong)(tong)能(neng)耗和運(yun)行(xing)費用(yong)，有效(xiao)地解決了提(ti)高室(shi)內空(kong)(kong)氣(qi)(qi)品(pin)質(zhi)與(yu)空(kong)(kong)調(diao)(diao)(diao)(diao)節(jie)(jie)(jie)能(neng)之間的(de)(de)矛盾，在空(kong)(kong)調(diao)(diao)(diao)(diao)系(xi)統(tong)(tong)節(jie)(jie)(jie)能(neng)領域中(zhong)具有不(bu)可替代(dai)的(de)(de)作(zuo)用(yong)。全(quan)(quan)熱(re)(re)(re)(re)交(jiao)換器工(gong)作(zuo)原理是(shi)：產品(pin)工(gong)作(zuo)時(shi)，室(shi)內排(pai)(pai)風(feng)(feng)(feng)和新(xin)(xin)風(feng)(feng)(feng)分別(bie)呈正交(jiao)叉(cha)方(fang)式(shi)流(liu)經換熱(re)(re)(re)(re)器芯體時(shi)，由于氣(qi)(qi)流(liu)分隔板兩側氣(qi)(qi)流(liu)存(cun)在著溫差和蒸汽(qi)分壓差，兩股氣(qi)(qi)流(liu)通(tong)(tong)過分隔板時(shi)呈現(xian)傳熱(re)(re)(re)(re)傳質(zhi)現(xian)象，引(yin)起全(quan)(quan)熱(re)(re)(re)(re)交(jiao)換過程。夏季(ji)運(yun)行(xing)時(shi)，新(xin)(xin)風(feng)(feng)(feng)從空(kong)(kong)調(diao)(diao)(diao)(diao)排(pai)(pai)風(feng)(feng)(feng)獲(huo)得冷量(liang)，使溫度(du)降低，同(tong)時(shi)被空(kong)(kong)調(diao)(diao)(diao)(diao)風(feng)(feng)(feng)干燥，使新(xin)(xin)風(feng)(feng)(feng)含濕(shi)量(liang)降低；冬季(ji)運(yun)行(xing)時(shi)，新(xin)(xin)風(feng)(feng)(feng)從空(kong)(kong)調(diao)(diao)(diao)(diao)室(shi)排(pai)(pai)風(feng)(feng)(feng)獲(huo)得熱(re)(re)(re)(re)量(liang)，溫度(du)升高。這樣，通(tong)(tong)過換熱(re)(re)(re)(re)芯體的(de)(de)全(quan)(quan)熱(re)(re)(re)(re)換熱(re)(re)(re)(re)過程，讓新(xin)(xin)風(feng)(feng)(feng)從空(kong)(kong)調(diao)(diao)(diao)(diao)排(pai)(pai)風(feng)(feng)(feng)中(zhong)回收能(neng)量(liang)。
