對于用戶朋友們來說,使用乙二醇冷水機組之前,需要對乙(yi)二醇(chun)冷水機組有著深(shen)刻的認識,關于制冷系統、蒸發溫度(du)、冷凝溫度(du)等各種設備中的溫度(du),還是建議(yi)了解一下的。
乙(yi)二(er)醇(chun)冷水機組(zu)的制冷系(xi)統如果能安全運行的話(hua),需要(yao)注意三點(dian):
1、乙(yi)二(er)醇(chun)冷(leng)水機組制冷(leng)系統中的制冷(leng)劑壓力需要(yao)隨時(shi)觀察,避免出(chu)現(xian)異常高壓狀態,以(yi)免乙(yi)二(er)醇(chun)冷(leng)水機組出(chu)現(xian)破裂;
2、乙二(er)醇(chun)冷水機組不(bu)得(de)出現以(yi)及(ji)發生濕熱沖程、液擊的現象(xiang),以(yi)免損壞(huai)乙二(er)醇(chun)冷水機組;
3、注意及時保養乙二醇冷水機組的每(mei)個部件(jian),以(yi)免部件(jian)存(cun)在缺陷以(yi)及(ji)造成乙二(er)醇(chun)冷水機(ji)組故障。
乙(yi)(yi)二(er)(er)(er)醇冷(leng)(leng)(leng)(leng)水(shui)機(ji)(ji)組(zu)(zu)(zu)的(de)(de)(de)蒸(zheng)發溫(wen)(wen)(wen)(wen)(wen)度(du)是(shi)指(zhi)乙(yi)(yi)二(er)(er)(er)醇冷(leng)(leng)(leng)(leng)水(shui)機(ji)(ji)組(zu)(zu)(zu)內部蒸(zheng)發器內的(de)(de)(de)制(zhi)(zhi)冷(leng)(leng)(leng)(leng)劑在(zai)固定壓(ya)(ya)力下(xia)沸騰氣化時的(de)(de)(de)溫(wen)(wen)(wen)(wen)(wen)度(du)。冷(leng)(leng)(leng)(leng)凝(ning)(ning)(ning)(ning)溫(wen)(wen)(wen)(wen)(wen)度(du)為乙(yi)(yi)二(er)(er)(er)醇冷(leng)(leng)(leng)(leng)水(shui)機(ji)(ji)組(zu)(zu)(zu)冷(leng)(leng)(leng)(leng)凝(ning)(ning)(ning)(ning)器內的(de)(de)(de)氣體制(zhi)(zhi)冷(leng)(leng)(leng)(leng)劑,在(zai)一定的(de)(de)(de)壓(ya)(ya)力下(xia)凝(ning)(ning)(ning)(ning)結成液體的(de)(de)(de)溫(wen)(wen)(wen)(wen)(wen)度(du)稱為冷(leng)(leng)(leng)(leng)凝(ning)(ning)(ning)(ning)溫(wen)(wen)(wen)(wen)(wen)度(du)。乙(yi)(yi)二(er)(er)(er)醇冷(leng)(leng)(leng)(leng)水(shui)機(ji)(ji)組(zu)(zu)(zu)再(zai)冷(leng)(leng)(leng)(leng)卻(que)(或(huo)稱過冷(leng)(leng)(leng)(leng))溫(wen)(wen)(wen)(wen)(wen)度(du)是(shi)指(zhi)冷(leng)(leng)(leng)(leng)凝(ning)(ning)(ning)(ning)后的(de)(de)(de)液體制(zhi)(zhi)冷(leng)(leng)(leng)(leng)劑在(zai)冷(leng)(leng)(leng)(leng)凝(ning)(ning)(ning)(ning)壓(ya)(ya)力下(xia)被冷(leng)(leng)(leng)(leng)卻(que)到低于冷(leng)(leng)(leng)(leng)凝(ning)(ning)(ning)(ning)溫(wen)(wen)(wen)(wen)(wen)度(du)的(de)(de)(de)溫(wen)(wen)(wen)(wen)(wen)度(du)稱再(zai)冷(leng)(leng)(leng)(leng)卻(que)溫(wen)(wen)(wen)(wen)(wen)度(du)(或(huo)過冷(leng)(leng)(leng)(leng)溫(wen)(wen)(wen)(wen)(wen)度(du))。乙(yi)(yi)二(er)(er)(er)醇冷(leng)(leng)(leng)(leng)水(shui)機(ji)(ji)組(zu)(zu)(zu)的(de)(de)(de)中(zhong)間(jian)溫(wen)(wen)(wen)(wen)(wen)度(du),是(shi)指(zhi)雙(shuang)壓(ya)(ya)縮系(xi)統,中(zhong)間(jian)冷(leng)(leng)(leng)(leng)卻(que)器中(zhong)制(zhi)(zhi)冷(leng)(leng)(leng)(leng)劑在(zai)中(zhong)間(jian)壓(ya)(ya)力下(xia)所對應的(de)(de)(de)飽和溫(wen)(wen)(wen)(wen)(wen)度(du)稱為中(zhong)間(jian)溫(wen)(wen)(wen)(wen)(wen)度(du) 。
其(qi)實(shi),乙二醇冷水機組(zu)的溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)說(shuo)明是(shi)比較多的,那(nei)么,知道(dao)這些溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)之后該如(ru)何檢測(ce)乙二醇冷水(shui)機(ji)組壓(ya)縮(suo)(suo)機(ji)吸(xi)氣(qi)溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)和(he)排氣(qi)溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)呢?壓(ya)縮(suo)(suo)機(ji)的吸(xi)氣(qi)溫(wen)(wen)(wen)度(du)(du)(du)(du)(du),可以從壓(ya)縮(suo)(suo)機(ji)的吸(xi)氣(qi)閥前面的溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)計測(ce)得(de)。乙二醇冷水(shui)機(ji)組吸(xi)氣(qi)溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)一般都高于蒸發(fa)溫(wen)(wen)(wen)度(du)(du)(du)(du)(du),其高出的差值(zhi)取決于回氣(qi)管(guan)的長度(du)(du)(du)(du)(du)與管(guan)道(dao)保溫(wen)(wen)(wen)情況,一般應(ying)較蒸發(fa)溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)高 5~10,改(gai)變供液量可(ke)以(yi)調(diao)節過(guo)熱度;壓(ya)(ya)縮(suo)機的排(pai)氣(qi)(qi)(qi)(qi)溫(wen)度可(ke)以(yi)從排(pai)氣(qi)(qi)(qi)(qi)管路上的溫(wen)度計測得。乙二醇冷水機組(zu)排(pai)氣(qi)(qi)(qi)(qi)溫(wen)度與(吸(xi)、排(pai)氣(qi)(qi)(qi)(qi)的)壓(ya)(ya)力比及吸(xi)氣(qi)(qi)(qi)(qi)溫(wen)度成正比,吸(xi)氣(qi)(qi)(qi)(qi)過(guo)熱度越高、壓(ya)(ya)力比越大(da),排(pai)氣(qi)(qi)(qi)(qi)溫(wen)度就越高,否則相反。 一(yi)般排氣(qi)壓力稍高(gao)于冷凝壓力。
所(suo)以,大家對于乙二醇冷水機組這(zhe)些(xie)知(zhi)識都了(le)解么?為了(le)更(geng)好(hao)(hao)的運行乙二醇冷(leng)水機組這(zhe)些(xie)還是需要用戶好(hao)(hao)好(hao)(hao)了(le)解的。
