閉環制冷(leng)機制冷(leng)時并不從(cong)外部引進空氣(qi),這樣可(ke)以避免對內(nei)部組件的(de)(de)污染(ran)危害。制冷(leng)機通(tong)過(guo)內(nei)部的(de)(de)蒸發器帶走(zou)控制柜內(nei)的(de)(de)熱量,再通(tong)過(guo)冷(leng)凝器的(de)(de)出氣(qi)口將熱量開(kai)釋。
制(zhi)(zhi)(zhi)冷機(ji)可以(yi)在控(kong)制(zhi)(zhi)(zhi)柜內所答應的最(zui)高(gao)(gao)氣溫(wen)(wen)(wen)必須保持(chi)低于外(wai)部環(huan)境溫(wen)(wen)(wen)度(du)時使用(yong),使用(yong)制(zhi)(zhi)(zhi)冷機(ji)的的另一個(ge)原因是(shi)制(zhi)(zhi)(zhi)冷機(ji)的外(wai)部尺寸(cun)小于相(xiang)同功率的熱交換器。在很(hen)高(gao)(gao)的溫(wen)(wen)(wen)度(du)下,或者熱負載要求很(hen)高(gao)(gao)的制(zhi)(zhi)(zhi)冷量(liang)時通(tong)常也(ye)使用(yong)制(zhi)(zhi)(zhi)冷機(ji)。盡管同非定(ding)制(zhi)(zhi)(zhi)空(kong)調系統(tong)很(hen)相(xiang)似,這(zhe)些專門設(she)計的制(zhi)(zhi)(zhi)冷系統(tong)還(huan)是(shi)有些細微的差別,為了(le)避免控(kong)制(zhi)(zhi)(zhi)柜內的組(zu)件(jian)受到(dao)熱負荷(he)的沖擊(ji),通(tong)常會使用(yong)比非定(ding)制(zhi)(zhi)(zhi)空(kong)調系統(tong)高(gao)(gao)的蒸發(fa)器溫(wen)(wen)(wen)度(du),另一個(ge)非標準化的特性是(shi)監測和報告驅動程序,它(ta)能保證(zheng)位于遠(yuan)真個(ge)工作(zuo)職員(yuan)能獲得熱治理系統(tong)的運行(xing)(xing)信息(xi)以(yi)及了(le)解(jie)控(kong)制(zhi)(zhi)(zhi)柜內的運行(xing)(xing)狀態(tai)。雷子克公司的制(zhi)(zhi)(zhi)冷機(ji)設(she)計為可以(yi)運行(xing)(xing)在高(gao)(gao)于55℃環(huan)境溫(wen)(wen)(wen)度(du)中(例如(ru)熱帶國家)
盡管蒸發器能往除一些濕氣,但(dan)假如在維護(hu)時控(kong)制(zhi)柜(ju)被打(da)開,要控(kong)制(zhi)控(kong)制(zhi)柜(ju)內的(de)濕氣不是輕(qing)易(yi)的(de)。控(kong)制(zhi)柜(ju)內沒(mei)有外部環境空氣的(de)滲透,當控(kong)制(zhi)柜(ju)內的(de)溫度(du)(du)升高時,通常(chang)濕度(du)(du)也相對較低(di)。閉環制(zhi)冷機可以很安全地(di)安裝(zhuang)于控(kong)制(zhi)柜(ju),大連控(kong)制(zhi)柜(ju)的(de)防水和(he)防塵率必(bi)須穩(wen)定。
