[恒溫恒濕箱]恒溫恒濕箱內部溫度濕度是如何控制的(de)？

　　恒溫(wen)(wen)恒濕(shi)(shi)(shi)箱是產品(pin)放在規(gui)定的溫(wen)(wen)度及(ji)(ji)濕(shi)(shi)(shi)度，看產品(pin)的耐(nai)高溫(wen)(wen)，耐(nai)低(di)溫(wen)(wen)，以(yi)及(ji)(ji)抗濕(shi)(shi)(shi)度能(neng)力，那么恒溫(wen)(wen)恒濕(shi)(shi)(shi)箱同時具備加(jia)溫(wen)(wen)，降(jiang)溫(wen)(wen)，加(jia)濕(shi)(shi)(shi)，降(jiang)濕(shi)(shi)(shi)能(neng)力。

　　加(jia)(jia)溫(wen)(wen)(wen)裝置是(shi)(shi)控(kong)制(zhi)恒(heng)(heng)(heng)溫(wen)(wen)(wen)恒(heng)(heng)(heng)濕(shi)(shi)機(ji)是(shi)(shi)不是(shi)(shi)升溫(wen)(wen)(wen)關(guan)鍵環節;它是(shi)(shi)控(kong)制(zhi)器(qi)得到升溫(wen)(wen)(wen)指令時會(hui)輸出電壓(ya)給繼電器(qi)，大約3-12伏直流電加(jia)(jia)在固態(tai)繼電器(qi)上(shang)面(mian);它的交流端相當于導線接(jie)(jie)通(tong);接(jie)(jie)觸(chu)器(qi)也(ye)同時吸合，加(jia)(jia)熱(re)器(qi)兩端有電壓(ya)使其發熱(re)，通(tong)過循(xun)環風機(ji)帶動把熱(re)量帶到箱里，使恒(heng)(heng)(heng)溫(wen)(wen)(wen)恒(heng)(heng)(heng)濕(shi)(shi)機(ji)升溫(wen)(wen)(wen)，那溫(wen)(wen)(wen)度(du)(du)(du)快(kuai)達到你(ni)的設定(ding)值;控(kong)制(zhi)器(qi)通(tong)過加(jia)(jia)在固態(tai)繼電器(qi)通(tong)斷調(diao)節;我們在恒(heng)(heng)(heng)溫(wen)(wen)(wen)恒(heng)(heng)(heng)濕(shi)(shi)機(ji)看屏幕上(shang)加(jia)(jia)熱(re)出力(li)(li)多少來調(diao)節發熱(re)量;這是(shi)(shi)在89度(du)(du)(du)以(yi)上(shang)溫(wen)(wen)(wen)度(du)(du)(du)控(kong)制(zhi)，在89度(du)(du)(du)以(yi)下溫(wen)(wen)(wen)度(du)(du)(du)穩定(ding)如何控(kong)制(zhi)呢？恒(heng)(heng)(heng)溫(wen)(wen)(wen)恒(heng)(heng)(heng)濕(shi)(shi)機(ji)是(shi)(shi)在一邊通(tong)過固態(tai)繼電器(qi)發熱(re)出力(li)(li)多少;另通(tong)過壓(ya)縮機(ji)制(zhi)冷循(xun)環降溫(wen)(wen)(wen)達到動態(tai)平衡;溫(wen)(wen)(wen)度(du)(du)(du)恒(heng)(heng)(heng)定(ding)。

　　降溫(wen)(wen)(wen)是恒(heng)溫(wen)(wen)(wen)恒(heng)濕(shi)機(ji)重(zhong)要環(huan)節(jie)，是判定一(yi)臺恒(heng)溫(wen)(wen)(wen)恒(heng)濕(shi)機(ji)性能好壞重(zhong)要參(can)數，它包括(kuo)壓(ya)縮(suo)機(ji)、冷(leng)凝器(qi)、節(jie)流(liu)裝置、蒸(zheng)發器(qi)四大(da)組成。壓(ya)縮(suo)機(ji)是制冷(leng)系統(tong)心(xin)臟(zang)，它吸(xi)入低溫(wen)(wen)(wen)低壓(ya)氣體，變成高溫(wen)(wen)(wen)高壓(ya)氣體，通(tong)(tong)過(guo)(guo)(guo)冷(leng)凝成液(ye)體放出熱(re)量(liang)，通(tong)(tong)過(guo)(guo)(guo)風機(ji)帶走熱(re)量(liang)，所以恒(heng)溫(wen)(wen)(wen)恒(heng)濕(shi)機(ji)下面是熱(re)風原因，然后(hou)通(tong)(tong)過(guo)(guo)(guo)節(jie)流(liu)到(dao)為低壓(ya)液(ye)體，其次通(tong)(tong)過(guo)(guo)(guo)蒸(zheng)發器(qi)成為低溫(wen)(wen)(wen)低壓(ya)氣體最(zui)后(hou)回(hui)到(dao)壓(ya)縮(suo)機(ji);制冷(leng)劑(ji)在蒸(zheng)發器(qi)中(zhong)吸(xi)收(shou)熱(re)量(liang)完成氣化(hua)過(guo)(guo)(guo)程(cheng)重(zhong)而吸(xi)收(shou)熱(re)量(liang)，達到(dao)制冷(leng)目的，完成恒(heng)溫(wen)(wen)(wen)恒(heng)濕(shi)機(ji)降溫(wen)(wen)(wen)過(guo)(guo)(guo)程(cheng)。

　　加濕(shi)系(xi)統與加熱系(xi)統大致一(yi)樣;它是加熱器加熱水變成蒸汽過程(cheng);完成恒溫恒濕(shi)機加濕(shi)目的。

　　降濕系(xi)統(tong)也是靠制冷系(xi)統(tong)完成(cheng)，蒸發(fa)器放在(zai)恒溫恒濕機(ji)里面(mian);比較冷，恒溫恒濕機(ji)里面(mian)高濕氣體會(hui)見冷的物體冷凝成(cheng)液體;如(ru)此反復箱(xiang)體的高濕氣體會(hui)很少，達到降濕目的。
