高溫老化試驗箱的特點

 高溫老化試驗箱的特點
1、完美的造型設計：圓弧造型及表面噴塑處理，高質感外觀，并采用平面無反作用把手，操作容易，安全可靠。 
2、明亮，視野寬廣的大型觀察窗：采用三層真空鍍膜視窗和飛利浦節能熒光燈，無須雨刷除霧，保持清晰的觀測效     果，可隨時觀察試品的狀況。 
3、加濕系統管路與控制電路分離：加濕系統管路與電源、控制器、電路板分離，可避免因管路漏水而影響電路，提     高安全性。 
4、先進可靠的冷凍及控制系統：原裝進口歐美全封閉壓縮機，進口環保冷媒，世界知名品牌的冷凍器件，原裝進口     LCD觸摸屏控制器，界面友好，操作簡單易學。 
 
高溫老化試驗箱恒溫恒濕試驗箱工作原理： 
 
      制(zhi)冷(leng)(leng)(leng)(leng)(leng)(leng)工(gong)作(zuo)原理：制(zhi)冷(leng)(leng)(leng)(leng)(leng)(leng)循環采(cai)用逆卡若循環，該循環出兩個等溫(wen)(wen)過程和(he)兩個絕熱(re)過程組(zu)成(cheng)，其過程如下：制(zhi)冷(leng)(leng)(leng)(leng)(leng)(leng)劑(ji)經壓縮(suo)機(ji)絕熱(re)壓縮(suo)到較高(gao)(gao)的(de)(de)壓力，消耗了的(de)(de)功使(shi)排氣溫(wen)(wen)度升高(gao)(gao)，之后制(zhi)冷(leng)(leng)(leng)(leng)(leng)(leng)劑(ji)經冷(leng)(leng)(leng)(leng)(leng)(leng)凝器等溫(wen)(wen)地和(he)四周介質(zhi)進行(xing)(xing)熱(re)交換將熱(re)量(liang)傳給四周介質(zhi)。后制(zhi)冷(leng)(leng)(leng)(leng)(leng)(leng)劑(ji)經截流閥絕熱(re)膨脹做功，這時制(zhi)冷(leng)(leng)(leng)(leng)(leng)(leng)劑(ji)溫(wen)(wen)度降低(di)。最后制(zhi)冷(leng)(leng)(leng)(leng)(leng)(leng)劑(ji)通過蒸(zheng)發器等溫(wen)(wen)地從溫(wen)(wen)度較高(gao)(gao)的(de)(de)物體(ti)吸熱(re)，使(shi)被(bei)冷(leng)(leng)(leng)(leng)(leng)(leng)卻物體(ti)溫(wen)(wen)度降低(di)。此循環周而復始從而達到降溫(wen)(wen)之目(mu)的(de)(de)。本試驗箱之制(zhi)冷(leng)(leng)(leng)(leng)(leng)(leng)系(xi)(xi)統(tong)(tong)(tong)(tong)采(cai)用1套法國產(chan)泰康全封閉壓縮(suo)機(ji)所組(zu)成(cheng)的(de)(de)單元氟利昂制(zhi)冷(leng)(leng)(leng)(leng)(leng)(leng)系(xi)(xi)統(tong)(tong)(tong)(tong)。制(zhi)冷(leng)(leng)(leng)(leng)(leng)(leng)系(xi)(xi)統(tong)(tong)(tong)(tong)的(de)(de)設(she)計應用能量(liang)調(diao)節技術(shu),既(ji)能保證制(zhi)冷(leng)(leng)(leng)(leng)(leng)(leng)機(ji)組(zu)正常運(yun)(yun)行(xing)(xing),又(you)能對制(zhi)冷(leng)(leng)(leng)(leng)(leng)(leng)系(xi)(xi)統(tong)(tong)(tong)(tong)的(de)(de)能耗及制(zhi)冷(leng)(leng)(leng)(leng)(leng)(leng)量(liang)進行(xing)(xing)有效的(de)(de)調(diao)節，使(shi)制(zhi)冷(leng)(leng)(leng)(leng)(leng)(leng)系(xi)(xi)統(tong)(tong)(tong)(tong)保持在最佳的(de)(de)運(yun)(yun)行(xing)(xing)狀(zhuang)態。采(cai)用平(ping)衡調(diao)溫(wen)(wen),既(ji)在制(zhi)冷(leng)(leng)(leng)(leng)(leng)(leng)系(xi)(xi)統(tong)(tong)(tong)(tong)在連續工(gong)作(zuo)的(de)(de)情況下，控制(zhi)系(xi)(xi)統(tong)(tong)(tong)(tong)根(gen)據設(she)定(ding)之溫(wen)(wen)度點通過PID自(zi)動(dong)運(yun)(yun)算輸出的(de)(de)結果去控制(zhi)加熱(re)器的(de)(de)輸出量(liang)，最終達到一種動(dong)態平(ping)衡。
