高溫(wen)(wen)工(gong)(gong)業(ye)制(zhi)(zhi)冷(leng)機(ji)(ji)(ji)(5 ~ 30 °C)這種制(zhi)(zhi)冷(leng)機(ji)(ji)(ji)使用傳統的(de)(de)制(zhi)(zhi)冷(leng)劑(ji)，將溫(wen)(wen)度控制(zhi)(zhi)在(zai)5 ~ 30 °C 之間(jian)。結果表(biao)明，在(zai)調整(zheng)溫(wen)(wen)度控制(zhi)(zhi)范圍時，工(gong)(gong)業(ye)冷(leng)水機(ji)(ji)(ji)組(zu)的(de)(de)**溫(wen)(wen)度設定在(zai)5 °C，**溫(wen)(wen)度設定在(zai)30 °C，這是工(gong)(gong)業(ye)上應用最廣泛的(de)(de)溫(wen)(wen)度控制(zhi)(zhi)范圍。但在(zai)制(zhi)(zhi)定工(gong)(gong)業(ye)冷(leng)水機(ji)(ji)(ji)組(zu)方案時，有些要求(qiu)控制(zhi)(zhi)在(zai)3 °C，需要提(ti)高和確定。

中溫工業(ye)冷水機組(0 ~ 15 °C)的水在0 °C 時會(hui)結冰，這是大多數人(ren)都能理解的常識性問題。那么(me)，如果(guo)工業(ye)冷水機組需要(yao)零度(du)以下的低溫冷凍液，是否可(ke)以實現呢？當然(ran)，答案(an)是肯定的。中溫工業(ye)冷水機的溫度(du)可(ke)設定在攝氏0度(du)至15度(du)，并可(ke)使用(yong)氯化(hua)鈣(鹽水)或乙(yi)二(er)醇水溶液作為制冷劑。

低(di)溫(wen)工(gong)(gong)(gong)(gong)業冷(leng)水機(ji)組(zu)可(ke)提供 -15 ° C ~ -35 ° C 以下的(de)(de)低(di)溫(wen)工(gong)(gong)(gong)(gong)業冷(leng)水機(ji)組(zu)。它(ta)通常用于化(hua)工(gong)(gong)(gong)(gong)和(he)制(zhi)藥行業，用于反(fan)應器中的(de)(de)物料冷(leng)卻(que)或(huo)物料冷(leng)凝回收。深(shen)低(di)溫(wen)工(gong)(gong)(gong)(gong)業制(zhi)冷(leng)機(ji)能(neng)夠提供 -35 °C 以下的(de)(de)低(di)溫(wen)冷(leng)凍液(ye)的(de)(de)工(gong)(gong)(gong)(gong)業制(zhi)冷(leng)機(ji)稱(cheng)為深(shen)低(di)溫(wen)工(gong)(gong)(gong)(gong)業制(zhi)冷(leng)機(ji)。采(cai)用二(er)元或(huo)三元復合制(zhi)冷(leng)系統(tong)，又(you)稱(cheng)復合式(shi)工(gong)(gong)(gong)(gong)業制(zhi)冷(leng)機(ji)。因此，工(gong)(gong)(gong)(gong)業冷(leng)水機(ji)組(zu)的(de)(de)溫(wen)度控(kong)制(zhi)范圍(wei)確(que)實特別(bie)寬(kuan)。
