[恒溫恒濕試驗箱]恒(heng)(heng)溫(wen)恒(heng)(heng)濕(shi)試驗箱(xiang)不制冷的根本原因及該(gai)怎么(me)做？

　　恒溫恒濕(shi)試(shi)驗(yan)箱(xiang)用于檢測材(cai)料在各(ge)種(zhong)(zhong)環境下性(xing)能的設備(bei)及試(shi)驗(yan)各(ge)種(zhong)(zhong)材(cai)料耐(nai)(nai)熱、耐(nai)(nai)寒、耐(nai)(nai)干、耐(nai)(nai)濕(shi)性(xing)能。

　　由(you)于(yu)使用年(nian)代過久，缺發(fa)保養(yang)，導(dao)致恒溫(wen)恒濕(shi)試(shi)驗箱不制冷，遇到(dao)這(zhe)種情況，我們應該做如下行動(dong)：

　　1.由于(yu)恒溫(wen)恒濕試驗(yan)箱是溫(wen)度保持不住，觀(guan)察制冷(leng)壓縮(suo)機(ji)在試驗(yan)箱運行過程中(zhong)是否(fou)能(neng)夠(gou)啟(qi)動?壓縮(suo)機(ji)在環(huan)境試驗(yan)設備運行過程中(zhong)都能(neng)夠(gou)啟(qi)動，說明(ming)從主(zhu)電源到各(ge)壓縮(suo)機(ji)的電器線路正常，電器系統方(fang)面(mian)也沒有問題。

　　2、若恒溫恒濕試驗箱電(dian)氣(qi)系統沒有問(wen)題，繼續(xu)檢(jian)(jian)查(cha)制(zhi)冷系統。首(shou)先(xian)檢(jian)(jian)查(cha)兩組(zu)制(zhi)冷機組(zu)的低溫(R23)級壓縮機的排氣(qi)和吸氣(qi)壓力(li)都較正(zheng)常值偏低，而且吸氣(qi)壓力(li)呈抽空(kong)狀態，說明(ming)主制(zhi)冷機組(zu)的制(zhi)冷劑(ji)量不(bu)足。

　　3、用(yong)手(shou)摸主(zhu)機組R23壓(ya)縮機的(de)(de)排(pai)氣(qi)和吸氣(qi)管路(lu)，發現排(pai)氣(qi)管路(lu)的(de)(de)溫度不高，吸氣(qi)管路(lu)的(de)(de)溫度也不低(未結霜)，這也說明了主(zhu)機組的(de)(de)R23制(zhi)冷劑缺乏。
