控制特點：

試(shi)驗箱的(de)控(kong)制系統可說是整個設備的(de)心(xin)臟，掌管(guan)著(zhu)制冷、制熱、控(kong)濕(shi)、循環、控(kong)制等大(da)權。

在制(zhi)(zhi)冷方面，壓縮機是(shi)采(cai)用(yong)德國(guo)進口的(de)(de)壓縮機。制(zhi)(zhi)冷系統(tong)由高(gao)溫(wen)部(bu)(bu)分(fen)(fen)和低溫(wen)部(bu)(bu)分(fen)(fen)組成，恒(heng)溫(wen)恒(heng)濕(shi)試驗(yan)(yan)箱生產(chan)廠家，每一部(bu)(bu)分(fen)(fen)是(shi)一個相對獨立的(de)(de)制(zhi)(zhi)冷系統(tong)。高(gao)溫(wen)部(bu)(bu)分(fen)(fen)中制(zhi)(zhi)冷劑的(de)(de)蒸發吸收來(lai)自(zi)低溫(wen)部(bu)(bu)分(fen)(fen)的(de)(de)制(zhi)(zhi)冷劑的(de)(de)熱量而汽(qi)化(hua)；低溫(wen)部(bu)(bu)分(fen)(fen)制(zhi)(zhi)冷劑的(de)(de)蒸發則從被(bei)冷卻的(de)(de)對象(試驗(yan)(yan)機內的(de)(de)空氣)吸熱以(yi)獲取冷量。高(gao)溫(wen)部(bu)(bu)分(fen)(fen)和低溫(wen)部(bu)(bu)分(fen)(fen)之間是(shi)用(yong)一個蒸發冷凝(ning)器聯系起來(lai)，它(ta)既(ji)是(shi)高(gao)溫(wen)部(bu)(bu)分(fen)(fen)的(de)(de)冷凝(ning)器，也(ye)是(shi)低溫(wen)部(bu)(bu)分(fen)(fen)的(de)(de)冷凝(ning)器。

加(jia)熱系(xi)統(tong)采用(yong)完全獨(du)立的鎳鉻合金(jin)電加(jia)熱式(shi)，電阻率(lv)大、電阻溫(wen)(wen)度(du)系(xi)數小，在高溫(wen)(wen)下變形小且不易脆(cui)化，自(zi)身加(jia)熱溫(wen)(wen)度(du)可達1000～1500℃，泰州恒(heng)溫(wen)(wen)恒(heng)濕(shi)試驗箱(xiang)，使用(yong)壽(shou)命長。

加(jia)濕是恒(heng)溫恒(heng)濕試(shi)驗箱(xiang)不同(tong)于高(gao)低溫試(shi)驗箱(xiang)的(de)主要的(de)一(yi)部分，恒(heng)溫恒(heng)濕試(shi)驗箱(xiang)采(cai)用外置隔離(li)式，全(quan)不銹鋼鍋爐式淺表面蒸發式加(jia)濕器。除(chu)濕方式采(cai)用機械制(zhi)冷除(chu)濕，將空(kong)氣冷卻，使大于飽和含濕量(liang)的(de)水汽(qi)凝(ning)結析(xi)出，這樣就降低了濕度。

送風循環系統：空氣循環系統由耐溫低噪音空調型電機，多葉式離心風輪構成。它提供了試驗機內空氣的循環。
