高溫(wen)工(gong)(gong)業(ye)制(zhi)(zhi)(zhi)冷(leng)機(5 ~ 30 °C)這種制(zhi)(zhi)(zhi)冷(leng)機使用傳統的制(zhi)(zhi)(zhi)冷(leng)劑，將(jiang)溫(wen)度(du)控制(zhi)(zhi)(zhi)在(zai)(zai)5 ~ 30 °C 之(zhi)間。結(jie)果表明，在(zai)(zai)調整溫(wen)度(du)控制(zhi)(zhi)(zhi)范圍時，工(gong)(gong)業(ye)冷(leng)水機組的**溫(wen)度(du)設定(ding)(ding)(ding)在(zai)(zai)5 °C，**溫(wen)度(du)設定(ding)(ding)(ding)在(zai)(zai)30 °C，這是(shi)工(gong)(gong)業(ye)上應用最廣泛(fan)的溫(wen)度(du)控制(zhi)(zhi)(zhi)范圍。但在(zai)(zai)制(zhi)(zhi)(zhi)定(ding)(ding)(ding)工(gong)(gong)業(ye)冷(leng)水機組方案(an)時，有些要求控制(zhi)(zhi)(zhi)在(zai)(zai)3 °C，需要提高和確定(ding)(ding)(ding)。

中溫(wen)工業冷(leng)水(shui)機組(0 ~ 15 °C)的水(shui)在0 °C 時會結(jie)冰，這是(shi)大多數人都能理解的常識性(xing)問(wen)題(ti)。那么，如果工業冷(leng)水(shui)機組需要(yao)零度以下的低溫(wen)冷(leng)凍液(ye)，是(shi)否可以實現(xian)呢？當然，答案是(shi)肯定的。中溫(wen)工業冷(leng)水(shui)機的溫(wen)度可設定在攝氏(shi)0度至15度，并可使用氯化鈣(鹽水(shui))或乙二醇水(shui)溶液(ye)作為(wei)制冷(leng)劑。

低溫工(gong)(gong)業(ye)冷(leng)(leng)水機(ji)(ji)(ji)組可提供(gong) -15 ° C ~ -35 ° C 以(yi)下的(de)(de)低溫工(gong)(gong)業(ye)冷(leng)(leng)水機(ji)(ji)(ji)組。它通常用于化工(gong)(gong)和制(zhi)(zhi)(zhi)藥行(xing)業(ye)，用于反應(ying)器(qi)中的(de)(de)物(wu)料(liao)冷(leng)(leng)卻或(huo)物(wu)料(liao)冷(leng)(leng)凝回收。深(shen)低溫工(gong)(gong)業(ye)制(zhi)(zhi)(zhi)冷(leng)(leng)機(ji)(ji)(ji)能夠提供(gong) -35 °C 以(yi)下的(de)(de)低溫冷(leng)(leng)凍液的(de)(de)工(gong)(gong)業(ye)制(zhi)(zhi)(zhi)冷(leng)(leng)機(ji)(ji)(ji)稱為深(shen)低溫工(gong)(gong)業(ye)制(zhi)(zhi)(zhi)冷(leng)(leng)機(ji)(ji)(ji)。采用二元(yuan)或(huo)三元(yuan)復合(he)制(zhi)(zhi)(zhi)冷(leng)(leng)系統，又稱復合(he)式(shi)工(gong)(gong)業(ye)制(zhi)(zhi)(zhi)冷(leng)(leng)機(ji)(ji)(ji)。因此(ci)，工(gong)(gong)業(ye)冷(leng)(leng)水機(ji)(ji)(ji)組的(de)(de)溫度控制(zhi)(zhi)(zhi)范圍確(que)實特別(bie)寬。
