機(ji)(ji)(ji)房是(shi)(shi)一個(ge)先進的(de)空調(diao)高(gao)(gao)溫(wen)(wen)(wen)(wen)(wen)(wen)工業(ye)(ye)制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)機(ji)(ji)(ji)(5 ~ 30 °C)。這(zhe)種(zhong)(zhong)制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)機(ji)(ji)(ji)使用傳統的(de)制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)劑，可以將溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)保持(chi)在(zai)5至(zhi)30攝氏(shi)(shi)度(du)(du)(du)之間。冷(leng)(leng)(leng)(leng)水(shui)(shui)(shui)機(ji)(ji)(ji)組(zu)(zu)是(shi)(shi)一種(zhong)(zhong)能(neng)提(ti)供恒(heng)溫(wen)(wen)(wen)(wen)(wen)(wen)、恒(heng)流(liu)、恒(heng)壓的(de)冷(leng)(leng)(leng)(leng)卻水(shui)(shui)(shui)設(she)備(bei)。冷(leng)(leng)(leng)(leng)水(shui)(shui)(shui)機(ji)(ji)(ji)的(de)回(hui)水(shui)(shui)(shui)溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)不應(ying)高(gao)(gao)于攝氏(shi)(shi)40度(du)(du)(du)。回(hui)水(shui)(shui)(shui)溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)越高(gao)(gao)，對(dui)壓縮(suo)機(ji)(ji)(ji)的(de)損傷越大。也就是(shi)(shi)說，在(zai)調(diao)整溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)控(kong)制(zhi)(zhi)(zhi)類別時，工業(ye)(ye)冷(leng)(leng)(leng)(leng)水(shui)(shui)(shui)機(ji)(ji)(ji)組(zu)(zu)的(de)低溫(wen)(wen)(wen)(wen)(wen)(wen)設(she)定在(zai)5 °C，高(gao)(gao)溫(wen)(wen)(wen)(wen)(wen)(wen)設(she)定在(zai)30 °C，這(zhe)是(shi)(shi)目前(qian)工業(ye)(ye)上廣(guang)泛采用的(de)溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)控(kong)制(zhi)(zhi)(zhi)類別。然而，有些(xie)要求是(shi)(shi)在(zai)3 °C 下(xia)進行(xing)的(de)，這(zhe)需(xu)要在(zai)制(zhi)(zhi)(zhi)造業(ye)(ye)制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)機(ji)(ji)(ji)計劃中(zhong)(zhong)提(ti)出和判斷。中(zhong)(zhong)溫(wen)(wen)(wen)(wen)(wen)(wen)工業(ye)(ye)冷(leng)(leng)(leng)(leng)水(shui)(shui)(shui)機(ji)(ji)(ji)組(zu)(zu)(0 ~ 15 °C) ，水(shui)(shui)(shui)會凍結在(zai)0 °C，這(zhe)是(shi)(shi)老人和小(xiao)孩都知道的(de)一個(ge)普遍原理。那么，如果工業(ye)(ye)制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)機(ji)(ji)(ji)要求提(ti)供低于零的(de)低溫(wen)(wen)(wen)(wen)(wen)(wen)液(ye)體，這(zhe)可能(neng)嗎？答案(an)當然是(shi)(shi)一種(zhong)(zhong)判斷。中(zhong)(zhong)溫(wen)(wen)(wen)(wen)(wen)(wen)工業(ye)(ye)制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)機(ji)(ji)(ji)的(de)溫(wen)(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)可設(she)定在(zai)攝氏(shi)(shi)0度(du)(du)(du)至(zhi)15度(du)(du)(du)，而制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)劑可以是(shi)(shi)氯化鈣(鹽水(shui)(shui)(shui))或乙二醇水(shui)(shui)(shui)溶液(ye)。低溫(wen)(wen)(wen)(wen)(wen)(wen)工業(ye)(ye)冷(leng)(leng)(leng)(leng)水(shui)(shui)(shui)機(ji)(ji)(ji)組(zu)(zu)可提(ti)供攝氏(shi)(shi)零下(xia)15度(du)(du)(du)至(zhi)35度(du)(du)(du)以下(xia)的(de)低溫(wen)(wen)(wen)(wen)(wen)(wen)工業(ye)(ye)冷(leng)(leng)(leng)(leng)水(shui)(shui)(shui)機(ji)(ji)(ji)組(zu)(zu)。

它們通常用(yong)于(yu)化學和(he)(he)制藥工(gong)(gong)業(ye)，用(yong)于(yu)反應器材(cai)料(liao)的冷(leng)卻或材(cai)料(liao)的冷(leng)凝和(he)(he)回(hui)收。深低(di)溫(wen)工(gong)(gong)業(ye)冷(leng)水機(ji)組(zu)是指(zhi)機(ji)房(fang)復雜的空調系統能夠提供(gong) -35 °C 以下的低(di)溫(wen)制冷(leng)劑(ji)的工(gong)(gong)業(ye)冷(leng)水機(ji)組(zu)，它采用(yong)二元(yuan)(yuan)或三(san)元(yuan)(yuan)串(chuan)聯制冷(leng)系統，故又稱為串(chuan)聯工(gong)(gong)業(ye)冷(leng)水機(ji)組(zu)。由此(ci)可(ke)見，工(gong)(gong)業(ye)冷(leng)水機(ji)組(zu)的溫(wen)度控制范圍(wei)
