恒溫恒濕試驗箱不制冷的原因是什么引起的

                

      恒(heng)(heng)(heng)(heng)溫(wen)(wen)(wen)恒(heng)(heng)(heng)(heng)濕(shi)(shi)試(shi)(shi)(shi)(shi)驗箱(xiang)(xiang)是(shi)(shi)模擬(ni)產品在高(gao)溫(wen)(wen)(wen)、低溫(wen)(wen)(wen)、濕(shi)(shi)熱交(jiao)變環境(jing)下的(de)(de)適(shi)應(ying)性(xing)，恒(heng)(heng)(heng)(heng)溫(wen)(wen)(wen)恒(heng)(heng)(heng)(heng)濕(shi)(shi)試(shi)(shi)(shi)(shi)驗箱(xiang)(xiang)需(xu)要提供(gong)客戶需(xu)要的(de)(de)溫(wen)(wen)(wen)度及濕(shi)(shi)度，過(guo)高(gao)或者過(guo)低都會(hui)影響產品測試(shi)(shi)(shi)(shi)，恒(heng)(heng)(heng)(heng)溫(wen)(wen)(wen)恒(heng)(heng)(heng)(heng)濕(shi)(shi)試(shi)(shi)(shi)(shi)驗箱(xiang)(xiang)具備(bei)自動加(jia)(jia)溫(wen)(wen)(wen)，降溫(wen)(wen)(wen)，加(jia)(jia)濕(shi)(shi)，降濕(shi)(shi)能力。  恒(heng)(heng)(heng)(heng)溫(wen)(wen)(wen)恒(heng)(heng)(heng)(heng)濕(shi)(shi)試(shi)(shi)(shi)(shi)驗箱(xiang)(xiang)的(de)(de)加(jia)(jia)溫(wen)(wen)(wen)裝(zhuang)置是(shi)(shi)控(kong)制溫(wen)(wen)(wen)度高(gao)低的(de)(de)主要裝(zhuang)置，當控(kong)制系統得到升(sheng)溫(wen)(wen)(wen)指令時加(jia)(jia)溫(wen)(wen)(wen)裝(zhuang)置會(hui)輸(shu)出直流(liu)(liu)電電壓(ya)給繼(ji)(ji)電器(qi)加(jia)(jia)在固態(tai)繼(ji)(ji)電器(qi)上面，交(jiao)流(liu)(liu)端相當于導線接(jie)通(tong)，控(kong)制器(qi)通(tong)過(guo)加(jia)(jia)在固態(tai)繼(ji)(ji)電器(qi)通(tong)斷調節。

       降(jiang)溫速(su)度是判定(ding)一臺恒(heng)溫恒(heng)濕(shi)試(shi)驗(yan)箱性能(neng)好壞的(de)重(zhong)(zhong)要(yao)參數(shu)，降(jiang)溫由(you)(you)壓(ya)縮機(ji)、冷凝(ning)器(qi)、節(jie)(jie)流(liu)裝置、蒸發器(qi)四大組(zu)成(cheng)(cheng)。 壓(ya)縮機(ji)是制冷系統心臟，恒(heng)溫恒(heng)濕(shi)試(shi)驗(yan)箱由(you)(you)于壓(ya)縮機(ji)吸(xi)入低(di)(di)(di)溫低(di)(di)(di)壓(ya)氣(qi)體(ti)，變成(cheng)(cheng)高溫高壓(ya)氣(qi)體(ti)，通過(guo)(guo)冷凝(ning)成(cheng)(cheng)液體(ti)放出(chu)熱量，通過(guo)(guo)風機(ji)帶走熱量，然后(hou)通過(guo)(guo)節(jie)(jie)流(liu)到為低(di)(di)(di)壓(ya)液體(ti)，通過(guo)(guo)蒸汽(qi)發器(qi)成(cheng)(cheng)為低(di)(di)(di)溫低(di)(di)(di)壓(ya)氣(qi)體(ti)最后(hou)回到壓(ya)縮機(ji)。 制冷劑(ji)在蒸發器(qi)中吸(xi)收(shou)(shou)熱量完(wan)成(cheng)(cheng)氣(qi)化過(guo)(guo)程(cheng)重(zhong)(zhong)而(er)吸(xi)收(shou)(shou)熱量，達到制冷目的(de)，完(wan)成(cheng)(cheng)試(shi)驗(yan)箱降(jiang)溫過(guo)(guo)程(cheng)。

       恒溫恒濕試驗箱降濕系統是靠制冷系統完成，蒸發器放在濕熱老化試驗箱里面，如此反復箱體的高濕氣體會很少，達到降濕目的。加濕系統是加熱器加熱水變成蒸汽過程，用于恒溫恒濕試驗箱加濕目的。   恒溫恒濕試驗箱不制冷原因與周圍環境有關，溫度過高容易造成降溫速度慢。  東莞市恒工設備有限公司專業生產恒溫恒濕試驗箱,選用國外進口壓縮機，專業技術人員提供指導方法。 選恒溫恒濕試驗箱，就選恒工。
