高低(di)(di)(di)溫(wen)(wen)試(shi)驗箱(xiang)(xiang)的(de)(de)穩(wen)定性，就(jiu)要(yao)(yao)講到高低(di)(di)(di)溫(wen)(wen)試(shi)驗箱(xiang)(xiang)的(de)(de)制(zhi)冷(leng)(leng)系統。高低(di)(di)(di)溫(wen)(wen)試(shi)驗箱(xiang)(xiang)中單級制(zhi)冷(leng)(leng)循環基本.上采用(yong)的(de)(de)中溫(wen)(wen)制(zhi)冷(leng)(leng)劑是(shi)R404A，在- -個大氣(qi)壓(ya)下其蒸發溫(wen)(wen)度是(shi)-46.5°C ，但空(kong)氣(qi)降低(di)(di)(di)式冷(leng)(leng)凝器傳熱溫(wen)(wen)差(cha)通常取(qu)(qu)10°C左右(you)，也就(jiu)是(shi)說(shuo)箱(xiang)(xiang)內只能(neng)制(zhi)取(qu)(qu)- 36.5'C的(de)(de)低(di)(di)(di)溫(wen)(wen)，高低(di)(di)(di)溫(wen)(wen)試(shi)驗箱(xiang)(xiang)供應(ying)商，那么(me)想(xiang)要(yao)(yao)獲(huo)取(qu)(qu)更低(di)(di)(di)的(de)(de)溫(wen)(wen)度需要(yao)(yao)怎(zen)么(me)辦呢?這個時(shi)候就(jiu)可以(yi)通過(guo)調低(di)(di)(di)壓(ya)縮機的(de)(de)蒸發壓(ya)力，可以(yi)將(jiang)R404A制(zhi)冷(leng)(leng)劑的(de)(de)較(jiao)低(di)(di)(di)蒸發溫(wen)(wen)度降低(di)(di)(di)到-50°C ，所以(yi)要(yao)(yao)得到-50°C及以(yi)下的(de)(de)低(di)(di)(di)溫(wen)(wen)時(shi)就(jiu)采取(qu)(qu)中溫(wen)(wen)制(zhi)冷(leng)(leng)劑與低(di)(di)(di)溫(wen)(wen)制(zhi)冷(leng)(leng)劑復(fu)疊(die)式的(de)(de)制(zhi)冷(leng)(leng)循環，這樣才能(neng)保證(zheng)高低(di)(di)(di)溫(wen)(wen)試(shi)驗箱(xiang)(xiang)制(zhi)冷(leng)(leng)穩(wen)定性。

江蘇易騰(teng)檢測儀(yi)器有限(xian)公司是(shi)一家可靠性(xing)試(shi)驗(yan)(yan)(yan)設備的制造商，高低溫試(shi)驗(yan)(yan)(yan)箱價格，我(wo)們專(zhuan)注于可靠性(xing)試(shi)驗(yan)(yan)(yan)已有16余年，在(zai)此期間，我(wo)們竭(jie)盡(jin)所能，努(nu)力(li)為(wei)客戶提(ti)供(gong)完善的實(shi)驗(yan)(yan)(yan)室規(gui)劃方案，匹配合(he)適的試(shi)驗(yan)(yan)(yan)設備。

在做高低溫試驗箱環境(jing)試驗時，對(dui)所需(xu)試驗的(de)(de)(de)樣(yang)品(pin)性(xing)能(neng)、試驗條件(jian)/試驗程(cheng)序(xu)和試驗技術要熟(shu)悉(xi)，要對(dui)所使(shi)用的(de)(de)(de)試驗設(she)備(bei)的(de)(de)(de)技術性(xing)能(neng)要熟(shu)悉(xi)，對(dui)設(she)備(bei)的(de)(de)(de)構造要有(you)所了解，尤其是對(dui)控制器的(de)(de)(de)操作及性(xing)能(neng)要熟(shu)悉(xi)。還要仔(zi)細閱讀試驗設(she)備(bei)的(de)(de)(de)操作使(shi)用手冊(ce)，這樣(yang)可(ke)以避免(mian)因操作失(shi)誤而引起試驗設(she)備(bei)的(de)(de)(de)不正(zheng)常運行從而引起試驗樣(yang)品(pin)的(de)(de)(de)損壞(huai)，試驗數據的(de)(de)(de)不正(zheng)確。
