高溫工業(ye)(ye)制(zhi)(zhi)冷(leng)機(ji)(5 ~ 30 °C)這種(zhong)制(zhi)(zhi)冷(leng)機(ji)使用傳統的制(zhi)(zhi)冷(leng)劑，將(jiang)溫度(du)(du)(du)控制(zhi)(zhi)在5 ~ 30 °C 之間。結果表(biao)明(ming)，在調整溫度(du)(du)(du)控制(zhi)(zhi)范圍時，工業(ye)(ye)冷(leng)水機(ji)組(zu)的**溫度(du)(du)(du)設(she)定在5 °C，**溫度(du)(du)(du)設(she)定在30 °C，這是工業(ye)(ye)上應(ying)用最廣泛的溫度(du)(du)(du)控制(zhi)(zhi)范圍。但在制(zhi)(zhi)定工業(ye)(ye)冷(leng)水機(ji)組(zu)方案時，有些要(yao)求控制(zhi)(zhi)在3 °C，需要(yao)提高和確定。

中溫(wen)工業冷(leng)水機(ji)組(0 ~ 15 °C)的水在0 °C 時會結冰，這是(shi)大多數人(ren)都能理解的常(chang)識性問題。那么，如果工業冷(leng)水機(ji)組需要零度(du)以下的低溫(wen)冷(leng)凍液，是(shi)否可(ke)以實現(xian)呢？當然(ran)，答案是(shi)肯定(ding)(ding)的。中溫(wen)工業冷(leng)水機(ji)的溫(wen)度(du)可(ke)設定(ding)(ding)在攝(she)氏(shi)0度(du)至15度(du)，并可(ke)使(shi)用氯化鈣(鹽水)或(huo)乙二醇(chun)水溶液作為(wei)制冷(leng)劑。

低溫(wen)(wen)工(gong)(gong)(gong)業(ye)冷(leng)(leng)水(shui)機(ji)(ji)(ji)(ji)組可提(ti)供 -15 ° C ~ -35 ° C 以下的(de)低溫(wen)(wen)工(gong)(gong)(gong)業(ye)冷(leng)(leng)水(shui)機(ji)(ji)(ji)(ji)組。它(ta)通常用(yong)于(yu)化工(gong)(gong)(gong)和制藥行業(ye)，用(yong)于(yu)反應器中(zhong)的(de)物(wu)料(liao)冷(leng)(leng)卻或物(wu)料(liao)冷(leng)(leng)凝(ning)回收。深低溫(wen)(wen)工(gong)(gong)(gong)業(ye)制冷(leng)(leng)機(ji)(ji)(ji)(ji)能夠(gou)提(ti)供 -35 °C 以下的(de)低溫(wen)(wen)冷(leng)(leng)凍液的(de)工(gong)(gong)(gong)業(ye)制冷(leng)(leng)機(ji)(ji)(ji)(ji)稱(cheng)(cheng)為深低溫(wen)(wen)工(gong)(gong)(gong)業(ye)制冷(leng)(leng)機(ji)(ji)(ji)(ji)。采用(yong)二元或三元復合制冷(leng)(leng)系(xi)統，又稱(cheng)(cheng)復合式工(gong)(gong)(gong)業(ye)制冷(leng)(leng)機(ji)(ji)(ji)(ji)。因此，工(gong)(gong)(gong)業(ye)冷(leng)(leng)水(shui)機(ji)(ji)(ji)(ji)組的(de)溫(wen)(wen)度控制范圍(wei)確實特(te)別寬。
