[恒溫恒濕試驗箱]如何控制恒(heng)溫恒(heng)濕(shi)試(shi)驗箱內(nei)部溫度(du)與濕(shi)度(du)？

　　恒(heng)(heng)(heng)溫恒(heng)(heng)(heng)濕(shi)試驗(yan)(yan)(yan)箱(xiang)是試樣(yang)放在規定的溫度(du)及(ji)濕(shi)度(du)，看試樣(yang)的耐高溫，耐低溫，以(yi)及(ji)抗濕(shi)度(du)才能(neng)，那么(me)恒(heng)(heng)(heng)溫恒(heng)(heng)(heng)濕(shi)試驗(yan)(yan)(yan)機一起具(ju)有加溫，降溫，加濕(shi)，降濕(shi)才能(neng)。在日常運用(yong)恒(heng)(heng)(heng)溫恒(heng)(heng)(heng)濕(shi)試驗(yan)(yan)(yan)箱(xiang)做實(shi)驗(yan)(yan)(yan)的時分，要對恒(heng)(heng)(heng)溫恒(heng)(heng)(heng)濕(shi)箱(xiang)內部溫度(du)與濕(shi)度(du)進行(xing)操(cao)控(kong)，以(yi)保(bao)證非常好的實(shi)驗(yan)(yan)(yan)成(cheng)果。那么(me)要操(cao)控(kong)恒(heng)(heng)(heng)溫恒(heng)(heng)(heng)濕(shi)箱(xiang)內部溫度(du)與濕(shi)度(du)，具(ju)體有什么(me)辦法呢?

　　首要有兩種(zhong)辦法：

　　◆加溫操控

　　一、恒溫恒濕試驗箱首要靠加溫設備升溫。

　　二、加溫(wen)設(she)備(bei)：加溫(wen)設(she)備(bei)是操控(kong)恒溫(wen)恒濕機是不是升溫(wen)關鍵環節;它是操控(kong)器得到升溫(wen)指令時會輸出電壓給繼電器，具(ju)體步(bu)驟(zou)：

　　1、導(dao)線(xian)接通的(de)溝通端(duan);

　　2、電(dian)器靠操控器輸入電(dian)壓(ya)，輸入電(dian)壓(ya)大概3-12伏;

　　3、恒溫(wen)恒濕試驗(yan)箱靠經過循環(huan)風機股動把(ba)熱量(liang)帶到箱內(nei)升(sheng)溫(wen)。

　　4、加熱(re)器(qi)兩端電(dian)壓使吸(xi)合(he)觸器(qi)發熱(re);

　　三、溫度快到(dao)達(da)設定值(zhi)時(shi)，操控器經過加在固態繼(ji)電器通斷調理(li) 。

　　四、調理發熱量：

　　1、89度以下溫度操(cao)控(kong);

　　2、89度(du)以上溫度(du)操控首要靠在(zai)恒溫恒濕試(shi)驗箱看屏幕上加熱(re)出力(li)多少來調理(li)發(fa)熱(re)量。

　　①在(zai)一邊經過固態繼電(dian)器發(fa)熱出力(li)多少;

　　②經過壓縮機制冷循環降(jiang)溫(wen)(wen)到達動(dong)態平衡，溫(wen)(wen)度穩定。

　　◆降溫(wen)(wen)操(cao)控：降溫(wen)(wen)是(shi)恒(heng)溫(wen)(wen)恒(heng)濕機(ji)重要(yao)環節(jie)，是(shi)斷定一臺(tai)恒(heng)溫(wen)(wen)恒(heng)濕機(ji)功能(neng)好壞重要(yao)參數

　　一、恒溫(wen)恒濕試(shi)驗箱功能好壞的判斷首要依據降溫(wen)才能來;

　　二、制冷劑(ji)在蒸發(fa)器中吸(xi)收熱量完結氣化進(jin)程(cheng)重而吸(xi)收熱量，到達制冷意圖，完結恒溫恒濕試驗箱降溫進(jin)程(cheng)。

　　三、經過冷凝成液體放出熱(re)量，風(feng)機帶走(zou)熱(re)量，致(zhi)使恒(heng)溫(wen)恒(heng)濕試驗箱下面熱(re)風(feng)，再經過節省到為(wei)低(di)(di)壓(ya)液體，其(qi)次(ci)經過蒸發器成為(wei)低(di)(di)溫(wen)低(di)(di)壓(ya)氣體最終(zhong)回到壓(ya)縮機;

　　四、壓(ya)縮機(ji)吸入低溫低壓(ya)氣(qi)體(ti)，成為高溫高壓(ya)氣(qi)體(ti)系屬冷系統首要組件;

　　五、恒溫恒濕試驗箱由壓縮機、冷凝器、節省設(she)備、蒸發器四大(da)組成;

　　以上(shang)即是恒溫(wen)恒濕試驗箱內(nei)部溫(wen)度與濕度的兩(liang)種首要控制的辦法。希望(wang)能有助您對恒溫(wen)恒濕試驗箱更近一步的了解。
