調溫除濕機用蒸發器來給空氣降溫除濕

     調(diao)溫除(chu)(chu)(chu)(chu)濕(shi)(shi)機用(yong)(yong)蒸發器(qi)來給空(kong)(kong)氣降溫除(chu)(chu)(chu)(chu)濕(shi)(shi)，并(bing)回收系(xi)統(tong)的(de)冷(leng)凝(ning)熱，彌補空(kong)(kong)氣中(zhong)因為冷(leng)卻(que)除(chu)(chu)(chu)(chu)濕(shi)(shi)時散(san)失的(de)熱量，是(shi)一種高能效的(de)除(chu)(chu)(chu)(chu)濕(shi)(shi)方(fang)式，已經應用(yong)(yong)于糧食、木材等的(de)除(chu)(chu)(chu)(chu)濕(shi)(shi)干燥和(he)高濕(shi)(shi)空(kong)(kong)間的(de)除(chu)(chu)(chu)(chu)濕(shi)(shi)與溫度控(kong)制(zhi)。目前的(de)除(chu)(chu)(chu)(chu)濕(shi)(shi)調(diao)溫方(fang)案中(zhong)只能適用(yong)(yong)于比較(jiao)特定(ding)的(de)環境要(yao)求，調(diao)節能力差，適用(yong)(yong)范圍小。

　　而我國氣候(hou)類型(xing)多(duo)樣，大部分(fen)地區冬夏溫差大，熱、冷、濕(shi)(shi)(shi)負荷隨時間(jian)變化明顯，傳統(tong)的系統(tong)不能(neng)很好的滿(man)足實際的需要(yao)，全年使用時間(jian)短，也造成了設備的閑(xian)置和浪(lang)費。熱泵調(diao)(diao)溫除(chu)濕(shi)(shi)(shi)機是提供(gong)一(yi)種可以在(zai)不同(tong)室內、外溫度下(xia)對室內進行供(gong)熱、制(zhi)冷和除(chu)濕(shi)(shi)(shi)以滿(man)足室內溫濕(shi)(shi)(shi)度要(yao)求的熱泵型(xing)調(diao)(diao)溫調(diao)(diao)濕(shi)(shi)(shi)方法及其設備，以提高除(chu)濕(shi)(shi)(shi)調(diao)(diao)溫系統(tong)的性能(neng)，擴大除(chu)濕(shi)(shi)(shi)調(diao)(diao)溫系統(tong)的適(shi)用范圍(wei)。

　　調(diao)溫(wen)除濕(shi)(shi)機所(suo)示為一種熱(re)泵調(diao)溫(wen)調(diao)濕(shi)(shi)機組，由壓縮機、四(si)通(tong)閥(fa)、室(shi)外(wai)(wai)換(huan)(huan)熱(re)器(qi)(qi)(qi)、室(shi)內(nei)(nei)(nei)第(di)(di)二換(huan)(huan)熱(re)器(qi)(qi)(qi)、室(shi)內(nei)(nei)(nei)第(di)(di)一換(huan)(huan)熱(re)器(qi)(qi)(qi)、膨(peng)脹(zhang)閥(fa)等過制(zhi)(zhi)(zhi)冷(leng)劑管路連接成一個(ge)制(zhi)(zhi)(zhi)冷(leng)循環(huan)，其中(zhong)室(shi)外(wai)(wai)換(huan)(huan)熱(re)器(qi)(qi)(qi)與室(shi)內(nei)(nei)(nei)第(di)(di)二換(huan)(huan)熱(re)器(qi)(qi)(qi)兩個(ge)支路并聯(lian)，并在室(shi)內(nei)(nei)(nei)第(di)(di)二換(huan)(huan)熱(re)器(qi)(qi)(qi)的(de)(de)(de)支路上安裝用(yong)來控(kong)制(zhi)(zhi)(zhi)支路通(tong)斷的(de)(de)(de)電磁閥(fa)。通(tong)過四(si)通(tong)閥(fa)進行制(zhi)(zhi)(zhi)冷(leng)和(he)制(zhi)(zhi)(zhi)熱(re)模式轉(zhuan)換(huan)(huan)(制(zhi)(zhi)(zhi)冷(leng)時，制(zhi)(zhi)(zhi)冷(leng)劑流向(xiang)如圖(tu)中(zhong)實線(xian)箭頭所(suo)示;制(zhi)(zhi)(zhi)熱(re)時，制(zhi)(zhi)(zhi)冷(leng)劑流量如圖(tu)中(zhong)虛線(xian)箭頭所(suo)示)，恒(heng)溫(wen)恒(heng)濕(shi)(shi)機能(neng)夠滿足(zu)全年運行冷(leng)熱(re)負(fu)荷大范(fan)圍變化的(de)(de)(de)要(yao)求，并通(tong)過兩個(ge)并聯(lian)換(huan)(huan)熱(re)器(qi)(qi)(qi)支路的(de)(de)(de)通(tong)斷和(he)室(shi)外(wai)(wai)換(huan)(huan)熱(re)器(qi)(qi)(qi)風量或(huo)水(shui)量的(de)(de)(de)調(diao)節(jie)進行微量調(diao)節(jie)，能(neng)夠滿足(zu)不(bu)同濕(shi)(shi)/冷(leng)/熱(re)負(fu)荷的(de)(de)(de)需要(yao)，使(shi)得對室(shi)內(nei)(nei)(nei)溫(wen)度和(he)濕(shi)(shi)度都能(neng)較好(hao)的(de)(de)(de)控(kong)制(zhi)(zhi)(zhi)在設定范(fan)圍內(nei)(nei)(nei)。采用(yong)四(si)通(tong)閥(fa)換(huan)(huan)向(xiang)除霜(shuang)的(de)(de)(de)方法，實現不(bu)停(ting)機快速除霜(shuang)。
