[恒溫恒濕試驗箱]恒溫恒濕試(shi)驗箱(xiang)內部三(san)大系(xi)統(tong)是怎(zen)么運行的(de)？

　　恒溫恒濕(shi)(shi)試驗箱也稱恒溫恒濕(shi)(shi)試驗機(ji)、恒溫恒濕(shi)(shi)實驗箱、恒溫機(ji)或恒溫恒濕(shi)(shi)箱，用于檢測(ce)材料(liao)在(zai)各種環(huan)境下性能(neng)的設備及試驗各種材料(liao)耐(nai)熱、耐(nai)寒、耐(nai)干、耐(nai)濕(shi)(shi)性能(neng)。適合電子(zi)、電器、通訊、儀表、車(che)輛、塑膠(jiao)制(zhi)品、金(jin)屬(shu)、食(shi)品、化學、建材、醫(yi)療、航天等制(zhi)品檢測(ce)質量之用。

　　恒溫(wen)恒濕試(shi)驗箱內(nei)部三(san)大(da)系(xi)統是(shi)(shi)怎么運行(xing)的？很多客戶都不太清楚(chu)，今(jin)天跟隨(sui)小編了(le)解(jie)下恒溫(wen)恒濕試(shi)驗箱內(nei)部三(san)大(da)系(xi)統是(shi)(shi)怎么運行(xing)的？

　　1、恒溫(wen)(wen)恒濕(shi)試驗箱壓縮(suo)(suo)機(ji)制(zhi)(zhi)冷(leng)(leng)(leng)循環系統：蒸(zheng)發器(qi)(qi)中的(de)液(ye)態(tai)(tai)制(zhi)(zhi)冷(leng)(leng)(leng)劑(ji)吸(xi)收空(kong)(kong)氣的(de)熱(re)(re)量(空(kong)(kong)氣被降溫(wen)(wen)及除濕(shi))并開始(shi)蒸(zheng)發，致使制(zhi)(zhi)冷(leng)(leng)(leng)劑(ji)與(yu)空(kong)(kong)氣之(zhi)間形(xing)成(cheng)一定的(de)溫(wen)(wen)度(du)差，液(ye)態(tai)(tai)制(zhi)(zhi)冷(leng)(leng)(leng)劑(ji)完全蒸(zheng)發變為氣態(tai)(tai)，后被壓縮(suo)(suo)機(ji)吸(xi)入并壓縮(suo)(suo)(壓力(li)和溫(wen)(wen)度(du)增(zeng)加)，氣態(tai)(tai)制(zhi)(zhi)冷(leng)(leng)(leng)劑(ji)通過(guo)冷(leng)(leng)(leng)凝(ning)器(qi)(qi)(風(feng)冷(leng)(leng)(leng)/水(shui)冷(leng)(leng)(leng))吸(xi)收熱(re)(re)量，凝(ning)結成(cheng)液(ye)體(ti)。通過(guo)膨脹閥(或毛(mao)細管)節(jie)流后變成(cheng)低(di)溫(wen)(wen)低(di)壓制(zhi)(zhi)冷(leng)(leng)(leng)劑(ji)進入蒸(zheng)發器(qi)(qi)，完成(cheng)制(zhi)(zhi)冷(leng)(leng)(leng)劑(ji)循環過(guo)程;

　　2、恒(heng)溫(wen)恒(heng)濕(shi)(shi)(shi)(shi)試驗(yan)箱空(kong)(kong)氣(qi)循(xun)(xun)環系統：離心風(feng)機負責將空(kong)(kong)氣(qi)從回(hui)風(feng)口(kou)吸入(ru)，空(kong)(kong)氣(qi)經過蒸發器、加(jia)濕(shi)(shi)(shi)(shi)器、電(dian)加(jia)熱器，通過降溫(wen)或升溫(wen)、除濕(shi)(shi)(shi)(shi)或加(jia)濕(shi)(shi)(shi)(shi)后(hou)經送(song)(song)風(feng)口(kou)送(song)(song)到(dao)用戶試驗(yan)的(de)(de)空(kong)(kong)間(jian)內，送(song)(song)出的(de)(de)空(kong)(kong)氣(qi)與空(kong)(kong)間(jian)內的(de)(de)空(kong)(kong)氣(qi)混合(he)后(hou)回(hui)到(dao)回(hui)風(feng)口(kou)，如此循(xun)(xun)環運(yun)行達(da)到(dao)試驗(yan)溫(wen)度穩定。上(shang)述簡介的(de)(de)描述了恒(heng)溫(wen)恒(heng)濕(shi)(shi)(shi)(shi)試驗(yan)箱運(yun)行三大主要(yao)系統的(de)(de)工作形態，其相互(hu)之間(jian)不可分離的(de)(de)運(yun)行制約，最終達(da)到(dao)用戶試驗(yan)既定的(de)(de)效果及目的(de)(de);

　　3、恒(heng)溫(wen)(wen)恒(heng)濕(shi)(shi)(shi)試(shi)驗箱電(dian)器(qi)(qi)自(zi)控(kong)(kong)系(xi)統：這塊(kuai)包括(kuo)電(dian)源部(bu)分(fen)(fen)和自(zi)動(dong)(dong)控(kong)(kong)制(zhi)(zhi)部(bu)分(fen)(fen)。電(dian)源部(bu)分(fen)(fen)通過(guo)接觸器(qi)(qi)，對壓(ya)縮機、風扇(shan)、電(dian)加(jia)熱器(qi)(qi)、加(jia)濕(shi)(shi)(shi)器(qi)(qi)等(deng)供應(ying)電(dian)源自(zi)動(dong)(dong)控(kong)(kong)制(zhi)(zhi)部(bu)分(fen)(fen)，其部(bu)分(fen)(fen)為溫(wen)(wen)濕(shi)(shi)(shi)度控(kong)(kong)制(zhi)(zhi)及(ji)故障保護(hu)部(bu)分(fen)(fen)。溫(wen)(wen)濕(shi)(shi)(shi)度控(kong)(kong)制(zhi)(zhi)是(shi)通過(guo)溫(wen)(wen)濕(shi)(shi)(shi)度控(kong)(kong)制(zhi)(zhi)器(qi)(qi)，將回風的溫(wen)(wen)濕(shi)(shi)(shi)度與試(shi)驗設定的溫(wen)(wen)濕(shi)(shi)(shi)作對比，自(zi)動(dong)(dong)運行壓(ya)縮機、加(jia)濕(shi)(shi)(shi)器(qi)(qi)、電(dian)加(jia)熱等(deng)元件進行降溫(wen)(wen)、升溫(wen)(wen)、除濕(shi)(shi)(shi)，實現(xian)恒(heng)溫(wen)(wen)恒(heng)濕(shi)(shi)(shi)的自(zi)動(dong)(dong)控(kong)(kong)制(zhi)(zhi)。
