產品介紹

全空(kong)(kong)氣(qi)系(xi)統中(zhong)，冬季室外(wai)溫度過(guo)低的時(shi)(shi)間，利(li)用(yong)冷(leng)卻塔(ta)給(gei)內(nei)區直(zhi)接供冷(leng)的空(kong)(kong)調方(fang)式不(bu)易實現。此(ci)時(shi)(shi)，可以(yi)將室外(wai)冷(leng)空(kong)(kong)氣(qi)作(zuo)為冷(leng)源(yuan)(yuan)，用(yong)乙二醇(chun)溶液(ye)作(zuo)載冷(leng)劑，將室外(wai)的自(zi)然冷(leng)源(yuan)(yuan)引(yin)入室內(nei)給(gei)內(nei)區供冷(leng)。需要給(gei)外(wai)區供熱(re)而給(gei)內(nei)區供冷(leng)時(shi)(shi)，關(guan)閉冷(leng)水(shui)(shui)裝置，仍然用(yong)鍋爐或城市熱(re)水(shui)(shui)作(zuo)為熱(re)源(yuan)(yuan)給(gei)外(wai)區供熱(re)。  

    在室外(wai)安裝板(ban)式換(huan)(huan)(huan)(huan)熱(re)(re)器(qi)，由風(feng)(feng)機將室外(wai)的(de)(de)(de)冷(leng)(leng)空(kong)(kong)氣引入(ru)(ru)板(ban)式換(huan)(huan)(huan)(huan)熱(re)(re)器(qi)，乙二醇(chun)溶液和(he)室外(wai)冷(leng)(leng)空(kong)(kong)氣在板(ban)式換(huan)(huan)(huan)(huan)熱(re)(re)器(qi)中(zhong)(zhong)(zhong)進(jin)(jin)(jin)行(xing)熱(re)(re)交(jiao)換(huan)(huan)(huan)(huan)。被冷(leng)(leng)卻(que)的(de)(de)(de)乙二醇(chun)溶液進(jin)(jin)(jin)入(ru)(ru)內區(qu)的(de)(de)(de)空(kong)(kong)調(diao)裝置(zhi)，在裝置(zhi)中(zhong)(zhong)(zhong)與混合(he)空(kong)(kong)氣(新、回(hui)(hui)風(feng)(feng)進(jin)(jin)(jin)行(xing)混合(he)后的(de)(de)(de)空(kong)(kong)氣)進(jin)(jin)(jin)行(xing)熱(re)(re)交(jiao)換(huan)(huan)(huan)(huan)，混合(he)空(kong)(kong)氣被冷(leng)(leng)卻(que)，溫(wen)度(du)降(jiang)低后進(jin)(jin)(jin)入(ru)(ru)內區(qu)房間，給內區(qu)房間供(gong)冷(leng)(leng)。乙二醇(chun)溶液溫(wen)度(du)升高，再次回(hui)(hui)到室外(wai)的(de)(de)(de)板(ban)式換(huan)(huan)(huan)(huan)熱(re)(re)器(qi)中(zhong)(zhong)(zhong)，與室外(wai)的(de)(de)(de)冷(leng)(leng)空(kong)(kong)氣進(jin)(jin)(jin)行(xing)熱(re)(re)交(jiao)換(huan)(huan)(huan)(huan)，溫(wen)度(du)降(jiang)低后繼續循環。這(zhe)種熱(re)(re)交(jiao)換(huan)(huan)(huan)(huan)方式經常用在熱(re)(re)回(hui)(hui)收系統中(zhong)(zhong)(zhong)。乙二醇(chun)和(he)高溫(wen)排(pai)風(feng)(feng)進(jin)(jin)(jin)行(xing)熱(re)(re)交(jiao)換(huan)(huan)(huan)(huan)，溫(wen)度(du)升高后，進(jin)(jin)(jin)入(ru)(ru)新風(feng)(feng)機柜，給新風(feng)(feng)進(jin)(jin)(jin)行(xing)預(yu)熱(re)(re)。從而，回(hui)(hui)收排(pai)風(feng)(feng)中(zhong)(zhong)(zhong)的(de)(de)(de)熱(re)(re)量給新風(feng)(feng)加熱(re)(re)，節約電能(neng)，節省運行(xing)費。
    這種(zhong)將乙二(er)(er)醇(chun)(chun)溶液(ye)作為載冷(leng)(leng)劑，引(yin)入室(shi)外冷(leng)(leng)空氣(qi)中的冷(leng)(leng)量給內區供(gong)冷(leng)(leng)的方(fang)式是一種(zhong)很節能(neng)(neng)的空調方(fang)式。只需(xu)在室(shi)外裝設一臺板(ban)式換(huan)熱(re)器，運行(xing)(xing)時，冷(leng)(leng)水裝置關(guan)閉，只開啟風機和空調裝置就能(neng)(neng)夠引(yin)入天然冷(leng)(leng)源給內區供(gong)冷(leng)(leng)，節約了電能(neng)(neng)，減(jian)少了運行(xing)(xing)費用(yong)。但(dan)是，在利用(yong)室(shi)外冷(leng)(leng)量給內區供(gong)冷(leng)(leng)的過程中，冷(leng)(leng)空氣(qi)要與乙二(er)(er)醇(chun)(chun)進(jin)行(xing)(xing)熱(re)交(jiao)(jiao)換(huan)，乙二(er)(er)醇(chun)(chun)再與混合空氣(qi)進(jin)行(xing)(xing)熱(re)交(jiao)(jiao)換(huan)，經(jing)過兩次熱(re)交(jiao)(jiao)換(huan)后，冷(leng)(leng)量損失較大(da)，換(huan)熱(re)效率(lv)不高，一般低于60%。乙二(er)(er)醇(chun)(chun)濃度一般在25-40%。乙二(er)(er)醇(chun)(chun)水溶液(ye)密度比水大(da)，粘度也大(da)于水，而比熱(re)小于水，選用(yong)水泵(beng)時，加大(da)了水泵(beng)電機容(rong)量。
    DSLC乙二醇熱(re)回(hui)收定壓(ya)(ya)補水(shui)裝置的控制(zhi)(zhi)系(xi)統一(yi)般有(you)三(san)種(zhong)運(yun)行(xing)方式：1、循環系(xi)統和補水(shui)系(xi)統壓(ya)(ya)差和壓(ya)(ya)力(li)自動控制(zhi)(zhi)水(shui)泵(beng)起停；2、恒壓(ya)(ya)變頻控制(zhi)(zhi)水(shui)泵(beng)循環和補水(shui)流量；3、PID溫(wen)度壓(ya)(ya)力(li)控制(zhi)(zhi)調節(jie)閥(fa)控制(zhi)(zhi)給水(shui)循環和補水(shui)流量。
DSLC定(ding)壓補水(shui)裝置膨脹罐布(bu)置有單(dan)罐單(dan)泵(beng)，單(dan)罐雙泵(beng)，雙罐雙泵(beng)式等多種布(bu)置方(fang)式，機電一體化，氣(qi)水(shui)無污染(ran)，氮(dan)氣(qi)一次充氣(qi)反復(fu)多次使用，結(jie)構緊湊，維護使用方(fang)便。
