高(gao)溫(wen)(wen)工(gong)業制(zhi)(zhi)(zhi)冷(leng)機(5 ~ 30 °C)這(zhe)種制(zhi)(zhi)(zhi)冷(leng)機使用傳統的制(zhi)(zhi)(zhi)冷(leng)劑，將溫(wen)(wen)度控(kong)(kong)制(zhi)(zhi)(zhi)在(zai)5 ~ 30 °C 之間。結果表明，在(zai)調整溫(wen)(wen)度控(kong)(kong)制(zhi)(zhi)(zhi)范(fan)圍(wei)時(shi)，工(gong)業冷(leng)水機組的**溫(wen)(wen)度設定(ding)在(zai)5 °C，**溫(wen)(wen)度設定(ding)在(zai)30 °C，這(zhe)是工(gong)業上應用最廣泛的溫(wen)(wen)度控(kong)(kong)制(zhi)(zhi)(zhi)范(fan)圍(wei)。但在(zai)制(zhi)(zhi)(zhi)定(ding)工(gong)業冷(leng)水機組方案時(shi)，有些要求控(kong)(kong)制(zhi)(zhi)(zhi)在(zai)3 °C，需要提高(gao)和確定(ding)。

中(zhong)溫(wen)工業(ye)(ye)(ye)冷(leng)水(shui)(shui)機組(0 ~ 15 °C)的水(shui)(shui)在(zai)0 °C 時會(hui)結(jie)冰，這是(shi)大(da)多數人都能理(li)解的常(chang)識性問題(ti)。那(nei)么，如果工業(ye)(ye)(ye)冷(leng)水(shui)(shui)機組需(xu)要零度(du)以(yi)下的低溫(wen)冷(leng)凍液(ye)，是(shi)否可以(yi)實現呢？當然，答案是(shi)肯定的。中(zhong)溫(wen)工業(ye)(ye)(ye)冷(leng)水(shui)(shui)機的溫(wen)度(du)可設定在(zai)攝氏(shi)0度(du)至(zhi)15度(du)，并可使(shi)用氯化鈣(鹽水(shui)(shui))或乙二醇水(shui)(shui)溶液(ye)作為制冷(leng)劑(ji)。

低(di)溫(wen)(wen)工(gong)(gong)(gong)(gong)業(ye)冷(leng)水(shui)機組(zu)可提供 -15 ° C ~ -35 ° C 以(yi)下的(de)低(di)溫(wen)(wen)工(gong)(gong)(gong)(gong)業(ye)冷(leng)水(shui)機組(zu)。它通常用(yong)于化工(gong)(gong)(gong)(gong)和(he)制(zhi)(zhi)(zhi)藥行業(ye)，用(yong)于反應(ying)器中(zhong)的(de)物料冷(leng)卻或(huo)物料冷(leng)凝(ning)回收。深(shen)低(di)溫(wen)(wen)工(gong)(gong)(gong)(gong)業(ye)制(zhi)(zhi)(zhi)冷(leng)機能夠提供 -35 °C 以(yi)下的(de)低(di)溫(wen)(wen)冷(leng)凍(dong)液(ye)的(de)工(gong)(gong)(gong)(gong)業(ye)制(zhi)(zhi)(zhi)冷(leng)機稱為深(shen)低(di)溫(wen)(wen)工(gong)(gong)(gong)(gong)業(ye)制(zhi)(zhi)(zhi)冷(leng)機。采用(yong)二(er)元(yuan)或(huo)三元(yuan)復(fu)(fu)合(he)制(zhi)(zhi)(zhi)冷(leng)系統(tong)，又稱復(fu)(fu)合(he)式工(gong)(gong)(gong)(gong)業(ye)制(zhi)(zhi)(zhi)冷(leng)機。因(yin)此(ci)，工(gong)(gong)(gong)(gong)業(ye)冷(leng)水(shui)機組(zu)的(de)溫(wen)(wen)度控制(zhi)(zhi)(zhi)范圍確實(shi)特(te)別寬。
