步入式(shi)恒(heng)溫(wen)(wen)(wen)恒(heng)濕(shi)(shi)房簡(jian)單點(dian)講就是(shi)大型的恒(heng)溫(wen)(wen)(wen)恒(heng)濕(shi)(shi)試(shi)驗(yan)箱，但(dan)其(qi)同恒(heng)溫(wen)(wen)(wen)恒(heng)濕(shi)(shi)試(shi)驗(yan)箱有很(hen)多區別。可(ke)以準確(que)地(di)模擬低溫(wen)(wen)(wen)、高溫(wen)(wen)(wen)、高溫(wen)(wen)(wen)高濕(shi)(shi)、低溫(wen)(wen)(wen)低濕(shi)(shi)復雜的自然狀環境(jing)，其(qi)主要是(shi)用于檢測大型的部件或(huo)元件，溫(wen)(wen)(wen)度(du)范圍(wei)可(ke)做到(dao)-40℃～80℃（可(ke)交變(bian)溫(wen)(wen)(wen)度(du)范圍(wei)：-40℃～60℃ ）；濕(shi)(shi)度(du)范圍(wei)可(ke)做到(dao)30～98％R.H（可(ke)交變(bian)濕(shi)(shi)度(du)范圍(wei)：45～98％R.H）。可(ke)定制

恒(heng)溫(wen)(wen)(wen)恒(heng)濕試驗(yan)箱(xiang)又叫高(gao)低(di)溫(wen)(wen)(wen)交(jiao)變濕熱試驗(yan)箱(xiang)，區別在于名稱不一樣，其功能，特性，原理，結構，用途，使(shi)用方法均一樣。可(ke)以準(zhun)確地模擬低(di)溫(wen)(wen)(wen)、高(gao)溫(wen)(wen)(wen)、高(gao)溫(wen)(wen)(wen)高(gao)濕、低(di)溫(wen)(wen)(wen)低(di)濕復(fu)雜的自(zi)然狀(zhuang)環境，適(shi)用于塑膠、電子(zi)、食品(pin)、服裝、車輛、金屬、化學、建材(cai)，汽車零部(bu)件大(da)學科研單位等多種行業的產品(pin)可(ke)靠性檢測。

恒(heng)溫(wen)(wen)恒(heng)濕試驗箱(xiang)工作原理 　　制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)工作原理：制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)循(xun)環采用(yong)逆卡若循(xun)環，該循(xun)環出兩個等(deng)溫(wen)(wen)過程(cheng)和兩個絕熱(re)(re)過程(cheng)組成(cheng)(cheng)，其過程(cheng)如下：制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)劑(ji)經(jing)(jing)壓縮機絕熱(re)(re)壓縮到較(jiao)高的(de)(de)(de)(de)壓力(li)，消耗(hao)了的(de)(de)(de)(de)功使(shi)排氣溫(wen)(wen)度(du)升高，之(zhi)后制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)劑(ji)經(jing)(jing)冷(leng)(leng)(leng)(leng)凝器(qi)等(deng)溫(wen)(wen)地和四周介質進行熱(re)(re)交換將(jiang)熱(re)(re)量傳給四周介質。后制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)劑(ji)經(jing)(jing)截流閥絕熱(re)(re)膨(peng)脹做功，這(zhe)時制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)劑(ji)溫(wen)(wen)度(du)降(jiang)低。后制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)劑(ji)通過蒸(zheng)發器(qi)等(deng)溫(wen)(wen)地從溫(wen)(wen)度(du)較(jiao)高的(de)(de)(de)(de)物(wu)體吸熱(re)(re)，使(shi)被(bei)冷(leng)(leng)(leng)(leng)卻物(wu)體溫(wen)(wen)度(du)降(jiang)低。此循(xun)環周而復始從而達(da)到降(jiang)溫(wen)(wen)之(zhi)目(mu)的(de)(de)(de)(de)。本試驗箱(xiang)之(zhi)制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)系(xi)(xi)(xi)統(tong)(tong)(tong)采用(yong)1套法國產泰康全封閉(bi)壓縮機所組成(cheng)(cheng)的(de)(de)(de)(de)單(dan)元氟利昂制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)系(xi)(xi)(xi)統(tong)(tong)(tong)。制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)系(xi)(xi)(xi)統(tong)(tong)(tong)的(de)(de)(de)(de)設計應用(yong)能量調節(jie)技(ji)術,既(ji)能保證制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)機組正(zheng)常運行,又能對制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)系(xi)(xi)(xi)統(tong)(tong)(tong)的(de)(de)(de)(de)能耗(hao)及制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)量進行有效(xiao)的(de)(de)(de)(de)調節(jie)，使(shi)制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)系(xi)(xi)(xi)統(tong)(tong)(tong)保持在佳(jia)的(de)(de)(de)(de)運行狀態。采用(yong)平衡調溫(wen)(wen)（BTC）,既(ji)在制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)系(xi)(xi)(xi)統(tong)(tong)(tong)在連續工作的(de)(de)(de)(de)情況下，控(kong)制(zhi)(zhi)(zhi)系(xi)(xi)(xi)統(tong)(tong)(tong)根據設定之(zhi)溫(wen)(wen)度(du)點(dian)通過PID自動(dong)運算輸出的(de)(de)(de)(de)結果去控(kong)制(zhi)(zhi)(zhi)加熱(re)(re)器(qi)的(de)(de)(de)(de)輸出量，終(zhong)達(da)到一種動(dong)態平衡。
