[恒溫恒濕試驗箱]小型(xing)恒(heng)溫恒(heng)濕試驗(yan)箱(xiang)溫度穩定的控制方法
小型(xing)恒(heng)溫恒(heng)濕試驗箱控制方法如下:
一:加溫能力
1:加(jia)溫裝置(zhi)是控制小型恒溫恒濕試驗(yan)箱是不(bu)是升溫關鍵(jian)環(huan)節(jie);
2:它是(shi)控(kong)制器得(de)到升溫(wen)指令時(shi)會輸出(chu)電(dian)(dian)壓給繼(ji)電(dian)(dian)器,大約3-12伏直流電(dian)(dian)加(jia)在固態繼(ji)電(dian)(dian)器上面;它的交流端相(xiang)當(dang)于導(dao)線接(jie)通(tong);接(jie)觸器也同時(shi)吸合(he),加(jia)熱器兩端有電(dian)(dian)壓使其發熱,通(tong)過循環風機帶動把熱量帶到箱里,使恒(heng)溫(wen)恒(heng)濕試驗機升溫(wen);
3:那溫度快達(da)到你的(de)設定值;控制器通過加(jia)在固態繼電(dian)器通斷(duan)調節;
4:我們在恒溫(wen)恒濕(shi)(shi)試驗(yan)箱看屏(ping)幕上(shang)加熱出力多少來調節(jie)發(fa)熱量;這是(shi)在89度(du)(du)以上(shang)溫(wen)度(du)(du)控制(zhi),在89度(du)(du)以下溫(wen)度(du)(du)穩定(ding)如何控制(zhi)呢?恒溫(wen)恒濕(shi)(shi)試驗(yan)箱是(shi)在一邊通(tong)過(guo)固態(tai)繼(ji)電器發(fa)熱出力多少;另通(tong)過(guo)壓縮機制(zhi)冷循環(huan)降溫(wen)達到(dao)動態(tai)平衡(heng);溫(wen)度(du)(du)恒定(ding)。
二:降溫能力
1:恒溫恒濕(shi)試驗(yan)箱重(zhong)要(yao)環節,是(shi)判定一臺恒溫恒濕(shi)機性能好壞重(zhong)要(yao)參數,它包括壓縮機、冷(leng)凝器、節流裝置、蒸發器四大組成。
2:壓(ya)(ya)縮機(ji)是制(zhi)冷系(xi)統心(xin)臟,它吸入低(di)(di)(di)溫(wen)(wen)低(di)(di)(di)壓(ya)(ya)氣體(ti)(ti),變成(cheng)(cheng)(cheng)高(gao)溫(wen)(wen)高(gao)壓(ya)(ya)氣體(ti)(ti),通(tong)過(guo)冷凝(ning)成(cheng)(cheng)(cheng)液體(ti)(ti)放出熱量(liang),通(tong)過(guo)風機(ji)帶走熱量(liang),所以恒溫(wen)(wen)恒濕(shi)機(ji)下面是熱風原(yuan)因(yin),然后(hou)通(tong)過(guo)節流到為(wei)低(di)(di)(di)壓(ya)(ya)液體(ti)(ti),其次(ci)通(tong)過(guo)蒸發器(qi)成(cheng)(cheng)(cheng)為(wei)低(di)(di)(di)溫(wen)(wen)低(di)(di)(di)壓(ya)(ya)氣體(ti)(ti)最(zui)后(hou)回到壓(ya)(ya)縮機(ji);制(zhi)冷劑在(zai)蒸發器(qi)中(zhong)吸收熱量(liang)完(wan)成(cheng)(cheng)(cheng)氣化過(guo)程重而(er)吸收熱量(liang),達到制(zhi)冷目(mu)的,完(wan)成(cheng)(cheng)(cheng)恒溫(wen)(wen)恒濕(shi)機(ji)降溫(wen)(wen)過(guo)程。
三:降濕能力
降(jiang)濕系(xi)統也是靠制冷(leng)系(xi)統完成,蒸發器放在小型(xing)恒(heng)(heng)溫恒(heng)(heng)濕試驗箱里面;比較冷(leng),恒(heng)(heng)溫恒(heng)(heng)濕試驗箱里面高(gao)濕氣(qi)(qi)體會見冷(leng)的物體冷(leng)凝成液體;如此(ci)反復箱體的高(gao)濕氣(qi)(qi)體會很(hen)少,達到降(jiang)濕目的。
