1、檢查干燥(zao)過(guo)濾(lv)器是否老化，若老化了(le)應及時更換否則(ze)失去應有的干燥(zao)吸水功能導致結冰。
2、要檢查與(yu)保養加濕器內之儲水(shui)應每(mei)月更換一次，確(que)保水(shui)質清(qing)潔，加濕水(shui)盤應每(mei)個月至少清(qing)洗(xi)一次，確(que)保水(shui)流順(shun)暢
3、使用(yong)高純度(du)的制冷劑，若制冷劑水分過多充注會造成冰堵(du)。
4、在換季(ji)使用時，應該(gai)進行設備的保養，這樣在新一年得使用過程中才會減少故障的發生。

恒溫恒濕試驗箱加(jia)熱加(jia)濕原理
恒(heng)(heng)(heng)(heng)溫(wen)(wen)(wen)恒(heng)(heng)(heng)(heng)濕試(shi)驗箱(xiang)(xiang)加(jia)溫(wen)(wen)(wen)裝置是(shi)(shi)控(kong)(kong)(kong)制恒(heng)(heng)(heng)(heng)溫(wen)(wen)(wen)恒(heng)(heng)(heng)(heng)濕機是(shi)(shi)不是(shi)(shi)升(sheng)溫(wen)(wen)(wen)的關(guan)鍵(jian)環(huan)節，它是(shi)(shi)控(kong)(kong)(kong)制器(qi)(qi)得到升(sheng)溫(wen)(wen)(wen)指令時會輸(shu)出(chu)電(dian)壓給繼電(dian)器(qi)(qi)，大約3-12伏直流(liu)電(dian)加(jia)在固態(tai)繼電(dian)器(qi)(qi)上面，它的交流(liu)端相當于導線接通，接觸器(qi)(qi)也同時吸(xi)合，加(jia)熱(re)(re)(re)器(qi)(qi)兩端有電(dian)壓使(shi)其發熱(re)(re)(re)，通過循環(huan)風機帶(dai)動(dong)(dong)把(ba)熱(re)(re)(re)量(liang)帶(dai)到箱(xiang)(xiang)里，使(shi)恒(heng)(heng)(heng)(heng)溫(wen)(wen)(wen)恒(heng)(heng)(heng)(heng)濕機升(sheng)溫(wen)(wen)(wen)，那溫(wen)(wen)(wen)度(du)快達(da)到你的設定(ding)值(zhi)，控(kong)(kong)(kong)制器(qi)(qi)通過加(jia)在固態(tai)繼電(dian)器(qi)(qi)通斷調節，我們在恒(heng)(heng)(heng)(heng)溫(wen)(wen)(wen)恒(heng)(heng)(heng)(heng)濕機看(kan)屏幕上加(jia)熱(re)(re)(re)出(chu)力(li)多(duo)少來調節發熱(re)(re)(re)量(liang)，這是(shi)(shi)在89度(du)以上溫(wen)(wen)(wen)度(du)控(kong)(kong)(kong)制，在89度(du)以下溫(wen)(wen)(wen)度(du)穩定(ding)如何控(kong)(kong)(kong)制呢？恒(heng)(heng)(heng)(heng)溫(wen)(wen)(wen)恒(heng)(heng)(heng)(heng)濕機是(shi)(shi)在一邊通過固態(tai)繼電(dian)器(qi)(qi)發熱(re)(re)(re)出(chu)力(li)多(duo)少，另通過壓縮機制冷循環(huan)降溫(wen)(wen)(wen)達(da)到動(dong)(dong)態(tai)平(ping)衡，溫(wen)(wen)(wen)度(du)恒(heng)(heng)(heng)(heng)定(ding)。
恒(heng)溫(wen)恒(heng)濕(shi)(shi)試驗箱降(jiang)溫(wen)是(shi)恒(heng)溫(wen)恒(heng)濕(shi)(shi)機(ji)重要環節，是(shi)判定一(yi)臺恒(heng)溫(wen)恒(heng)濕(shi)(shi)機(ji)性能好壞重要參數(shu)，它包括壓縮(suo)(suo)機(ji)、冷(leng)(leng)凝器(qi)、節流(liu)(liu)裝置、蒸(zheng)發器(qi)四大組成(cheng)(cheng)。壓縮(suo)(suo)機(ji)是(shi)制(zhi)冷(leng)(leng)系統心臟(zang)，它吸(xi)入低(di)(di)溫(wen)低(di)(di)壓氣體(ti)，變成(cheng)(cheng)高(gao)溫(wen)高(gao)壓氣體(ti)，通過冷(leng)(leng)凝成(cheng)(cheng)液體(ti)放出熱(re)量，通過風(feng)機(ji)帶走熱(re)量，所(suo)以恒(heng)溫(wen)恒(heng)濕(shi)(shi)機(ji)下面是(shi)熱(re)風(feng)原因，然后通過節流(liu)(liu)到為低(di)(di)壓液體(ti)，其(qi)次通過蒸(zheng)發器(qi)成(cheng)(cheng)為低(di)(di)溫(wen)低(di)(di)壓氣體(ti)最后回到壓縮(suo)(suo)機(ji)，制(zhi)冷(leng)(leng)劑在蒸(zheng)發器(qi)中吸(xi)收熱(re)量完(wan)成(cheng)(cheng)氣化過程重而吸(xi)收熱(re)量，達到制(zhi)冷(leng)(leng)目的，完(wan)成(cheng)(cheng)恒(heng)溫(wen)恒(heng)濕(shi)(shi)機(ji)降(jiang)溫(wen)過程。
恒(heng)(heng)溫(wen)恒(heng)(heng)濕試(shi)驗(yan)箱(xiang)加濕系統與加熱(re)系統大致一樣，它是加熱(re)器加熱(re)水變成蒸汽過(guo)程，完成恒(heng)(heng)溫(wen)恒(heng)(heng)濕機加濕目的。
恒(heng)溫恒(heng)濕(shi)(shi)(shi)試驗箱降濕(shi)(shi)(shi)系統也是靠制(zhi)冷(leng)系統完(wan)成(cheng)，蒸發(fa)器(qi)放在恒(heng)溫恒(heng)濕(shi)(shi)(shi)機里面(mian)，比較冷(leng)，恒(heng)溫恒(heng)濕(shi)(shi)(shi)機里面(mian)高濕(shi)(shi)(shi)氣體(ti)(ti)(ti)會見(jian)冷(leng)的物體(ti)(ti)(ti)冷(leng)凝成(cheng)液體(ti)(ti)(ti)，如此反復(fu)箱體(ti)(ti)(ti)的高濕(shi)(shi)(shi)氣體(ti)(ti)(ti)會很少，達(da)到降濕(shi)(shi)(shi)目的。
恒(heng)溫(wen)恒(heng)濕箱(xiang)內箱(xiang)溫(wen)濕度(du)均勻度(du)的因素寶
影響(xiang)恒溫(wen)恒濕(shi)箱(xiang)溫(wen)濕(shi)度均(jun)勻度的主(zhu)要因(yin)素：
A、熱負載：如(ru)(ru)果(guo)如(ru)(ru)果(guo)試驗箱工作(zuo)室內(nei)放置了足夠(gou)影(ying)(ying)響(xiang)內(nei)部(bu)整體(ti)熱對流的(de)試驗樣品(pin)，必然會在一定程度上影(ying)(ying)響(xiang)內(nei)部(bu)溫度的(de)均(jun)勻(yun)性，比如(ru)(ru)說放置LED照(zhao)明產(chan)品(pin)，產(chan)品(pin)自身存在發光發熱，成為熱負載，那么對于溫度均(jun)勻(yun)度的(de)就存在很(hen)大(da)的(de)影(ying)(ying)響(xiang)。
B、熱(re)(re)傳(chuan)遞：由于工(gong)作(zuo)室(shi)的箱壁前后左右上下6個面的傳(chuan)熱(re)(re)系數不(bu)同，有(you)(you)(you)的有(you)(you)(you)穿線(xian)孔(kong)(kong)、檢測孔(kong)(kong)、測試孔(kong)(kong)等導致局部有(you)(you)(you)散熱(re)(re)、傳(chuan)熱(re)(re)，使箱體溫度(du)不(bu)均(jun)勻，從而使箱壁幅射對(dui)流(liu)傳(chuan)熱(re)(re)也不(bu)均(jun)勻，影響溫度(du)均(jun)勻。
C、熱(re)輻射(she)：設(she)計(ji)上的(de)(de)問(wen)題導致驗(yan)箱(xiang)在內部結(jie)構、空間的(de)(de)設(she)計(ji)很難達到(dao)均勻的(de)(de)對(dui)稱結(jie)構，恒(heng)溫(wen)恒(heng)濕試驗(yan)箱(xiang)而不(bu)對(dui)稱的(de)(de)結(jie)構必然會導致內部溫(wen)度均勻度產生偏差，這個(ge)層面(mian)(mian)主要(yao)反映在鈑金(jin)(jin)設(she)計(ji)以及鈑金(jin)(jin)處理方面(mian)(mian)，諸如：風(feng)道(dao)的(de)(de)設(she)計(ji)、發(fa)熱(re)管的(de)(de)放置位置、風(feng)機功率的(de)(de)大小等原因(yin)。
D、密(mi)(mi)封(feng)性：箱體和門(men)的(de)密(mi)(mi)封(feng)性不嚴，比如：密(mi)(mi)封(feng)條非(fei)定制的(de)有(you)接縫，大門(men)漏(lou)氣等，從而影響工作空(kong)間(jian)的(de)溫度均勻性。
E、被測樣品選擇與擺(bai)放的(de)合(he)理性(xing)：如果試(shi)驗對象體積過大，恒(heng)溫(wen)恒(heng)濕箱或(huo)試(shi)驗對象放置(zhi)在(zai)試(shi)驗箱工(gong)作室內的(de)位置(zhi)或(huo)方式不(bu)合(he)適，使里面空氣對流受阻，也會(hui)產生較大的(de)溫(wen)度均(jun)(jun)勻(yun)度的(de)偏差。諸如將試(shi)驗產品放在(zai)風道旁邊，嚴重影響風的(de)循環(huan)，當然溫(wen)度的(de)均(jun)(jun)勻(yun)度會(hui)受到很大的(de)影響。
F、由于內(nei)壁結構不(bu)同(tong)，所以(yi)會(hui)導致試(shi)驗箱內(nei)壁的溫度也會(hui)不(bu)均(jun)勻(yun)(yun)，進而影(ying)響工作室內(nei)的熱對流造成內(nei)部溫度均(jun)勻(yun)(yun)度產生偏(pian)差。
