通(tong)過三個相互聯系(xi)的(de)系(xi)統：制冷劑(ji)循環系(xi)統、空氣循環系(xi)統、電器(qi)自(zi)控系(xi)統。

一(yi)、恒溫(wen)恒濕(shi)試驗(yan)箱制(zhi)冷(leng)劑(ji)循環系統(tong)：蒸(zheng)(zheng)發(fa)(fa)器(qi)中(zhong)的(de)液(ye)(ye)態(tai)(tai)(tai)制(zhi)冷(leng)劑(ji)吸收(shou)空氣(qi)的(de)熱量(liang)(空氣(qi)被(bei)降溫(wen)及除濕(shi))并開始(shi)蒸(zheng)(zheng)發(fa)(fa)，終制(zhi)冷(leng)劑(ji)與空之(zhi)間(jian)形成一(yi)定的(de)溫(wen)度(du)差(cha)，液(ye)(ye)態(tai)(tai)(tai)制(zhi)冷(leng)劑(ji)亦(yi)完全蒸(zheng)(zheng)發(fa)(fa)變為氣(qi)態(tai)(tai)(tai)，后被(bei)壓縮機(ji)吸入并壓縮(壓力(li)和溫(wen)度(du)增加)，氣(qi)態(tai)(tai)(tai)制(zhi)冷(leng)劑(ji)通(tong)過(guo)(guo)冷(leng)凝器(qi)(風冷(leng)/水冷(leng))吸收(shou)熱量(liang)，恒溫(wen)恒濕(shi)試驗(yan)箱廠(chang)家，凝結成液(ye)(ye)體。通(tong)過(guo)(guo)膨(peng)脹閥(或毛細(xi)管)節流后變成低溫(wen)低壓制(zhi)冷(leng)劑(ji)進入蒸(zheng)(zheng)發(fa)(fa)器(qi)，完成制(zhi)冷(leng)劑(ji)循環過(guo)(guo)程。

二、恒(heng)溫(wen)恒(heng)濕試(shi)驗箱空氣(qi)環系統(tong)：風機負責(ze)將空氣(qi)從(cong)回風口吸入，空氣(qi)經過蒸發器(降溫(wen)、除濕)，加濕器，電加熱器(升(sheng)溫(wen))后經送(song)(song)風口送(song)(song)到用戶需的空間內(nei)(nei)，送(song)(song)出的空氣(qi)與(yu)空間內(nei)(nei)的空氣(qi)混合(he)后回到回風口。

三、恒溫恒濕試驗箱電器自控系統：包括電源部分和自動控制部分。電源部分通過接觸器，對壓縮機、風扇、電加器器，加濕器等供應電源自動控制分部分又分為溫、濕度控制及故障保護部分:溫、濕度控制是通過溫、濕度控制器，將回風的溫濕度與用戶設定的溫濕作對比，自動運行壓縮機(降溫、除濕)，加濕器，電加熱(升溫)等元件，實現恒溫恒濕的自動控制。

加(jia)(jia)濕(shi)(shi)(shi)器內有(you)水(shui)(shui)位浮(fu)球，舟山恒(heng)(heng)溫(wen)恒(heng)(heng)濕(shi)(shi)(shi)試驗(yan)(yan)(yan)(yan)(yan)箱，長(chang)時(shi)間(jian)之后(hou)不換水(shui)(shui)容(rong)易造成(cheng)(cheng)水(shui)(shui)位浮(fu)球短(duan)路(lu)，會(hui)(hui)造成(cheng)(cheng)無法加(jia)(jia)濕(shi)(shi)(shi)等現(xian)象。一般用(yong)(yong)(yong)戶在選(xuan)擇恒(heng)(heng)溫(wen)恒(heng)(heng)濕(shi)(shi)(shi)試驗(yan)(yan)(yan)(yan)(yan)箱廠家(jia)的(de)(de)時(shi)候，技(ji)術員都有(you)溫(wen)馨提示和技(ji)術指導，可(ke)(ke)(ke)以咨詢是(shi)否能安裝(zhuang)自(zi)然水(shui)(shui)過濾(lv)系統(tong)，過濾(lv)后(hou)自(zi)然水(shui)(shui)也可(ke)(ke)(ke)以轉化成(cheng)(cheng)純凈(jing)水(shui)(shui)，如此(ci)(ci)一來，可(ke)(ke)(ke)以直接將水(shui)(shui)中(zhong)的(de)(de)雜質過濾(lv)，使(shi)得恒(heng)(heng)溫(wen)恒(heng)(heng)濕(shi)(shi)(shi)試驗(yan)(yan)(yan)(yan)(yan)箱中(zhong)使(shi)用(yong)(yong)(yong)的(de)(de)水(shui)(shui)是(shi)過濾(lv)后(hou)的(de)(de)純凈(jing)水(shui)(shui)。因普通(tong)用(yong)(yong)(yong)水(shui)(shui)加(jia)(jia)濕(shi)(shi)(shi)粒(li)子比較大，恒(heng)(heng)溫(wen)恒(heng)(heng)濕(shi)(shi)(shi)試驗(yan)(yan)(yan)(yan)(yan)箱價格，長(chang)時(shi)間(jian)進行濕(shi)(shi)(shi)度試驗(yan)(yan)(yan)(yan)(yan)，那(nei)么對濕(shi)(shi)(shi)度恒(heng)(heng)溫(wen)恒(heng)(heng)濕(shi)(shi)(shi)試驗(yan)(yan)(yan)(yan)(yan)箱傳感器的(de)(de)使(shi)用(yong)(yong)(yong)壽命必(bi)然會(hui)(hui)有(you)影響，可(ke)(ke)(ke)能會(hui)(hui)造成(cheng)(cheng)濕(shi)(shi)(shi)度傳感器短(duan)路(lu)。對此(ci)(ci)，實驗(yan)(yan)(yan)(yan)(yan)用(yong)(yong)(yong)水(shui)(shui)要求(qiu)相(xiang)對要嚴格一些，還是(shi)采(cai)用(yong)(yong)(yong)純凈(jing)水(shui)(shui)或去(qu)氧離(li)子水(shui)(shui)。

江(jiang)蘇易騰檢測儀器有限公司是一家可靠性試驗(yan)設(she)備(bei)的制造商，我(wo)(wo)們專注于可靠性試驗(yan)已有16余(yu)年，在此期(qi)間，我(wo)(wo)們竭盡所能，努(nu)力為客(ke)戶提供(gong)完(wan)善的實驗(yan)室規(gui)劃方(fang)案，匹(pi)配(pei)合適的試驗(yan)設(she)備(bei)。

恒溫(wen)恒濕(shi)(shi)(shi)(shi)(shi)(shi)試(shi)驗機(ji)的(de)(de)除(chu)濕(shi)(shi)(shi)(shi)(shi)(shi)原(yuan)理(li)：①干(gan)燥(zao)(zao)器除(chu)濕(shi)(shi)(shi)(shi)(shi)(shi)是(shi)使(shi)(shi)用氣(qi)泵將試(shi)驗機(ji)中(zhong)的(de)(de)空氣(qi)抽出(chu)并(bing)(bing)注入干(gan)燥(zao)(zao)的(de)(de)空氣(qi)。同時，潮濕(shi)(shi)(shi)(shi)(shi)(shi)的(de)(de)空氣(qi)被(bei)送至(zhi)可循環(huan)干(gan)燥(zao)(zao)機(ji)進行干(gan)燥(zao)(zao)，干(gan)燥(zao)(zao)后再送至(zhi)試(shi)驗機(ji)。 在(zai)該循環(huan)中(zhong)重(zhong)復除(chu)濕(shi)(shi)(shi)(shi)(shi)(shi)。②漏氣(qi)濕(shi)(shi)(shi)(shi)(shi)(shi)度控(kong)制(zhi)：在(zai)主(zhu)系統中(zhong)開一(yi)個通(tong)風孔，以人為地產生蒸汽泄漏。③制(zhi)冷(leng)(leng)(leng)除(chu)濕(shi)(shi)(shi)(shi)(shi)(shi)方(fang)法：利用制(zhi)冷(leng)(leng)(leng)機(ji)使(shi)(shi)潮濕(shi)(shi)(shi)(shi)(shi)(shi)的(de)(de)空氣(qi)凝結和結霜，達到除(chu)濕(shi)(shi)(shi)(shi)(shi)(shi)的(de)(de)目的(de)(de)。④噴水(shui)除(chu)濕(shi)(shi)(shi)(shi)(shi)(shi)法：將冷(leng)(leng)(leng)水(shui)噴入測試(shi)室進行除(chu)濕(shi)(shi)(shi)(shi)(shi)(shi)。該方(fang)法受區域季節(jie)的(de)(de)影響很大(da)。例如，在(zai)南部的(de)(de)炎熱季節(jie)要找到冷(leng)(leng)(leng)水(shui)并(bing)(bing)不容易，生產冷(leng)(leng)(leng)水(shui)并(bing)(bing)挖深井來獲(huo)取水(shui)也不經濟。⑤機(ji)械制(zhi)冷(leng)(leng)(leng)除(chu)濕(shi)(shi)(shi)(shi)(shi)(shi)的(de)(de)除(chu)濕(shi)(shi)(shi)(shi)(shi)(shi)原(yuan)理(li)是(shi)將空氣(qi)冷(leng)(leng)(leng)卻到露i點溫(wen)度以下，以凝結大(da)于飽(bao)和水(shui)分含量的(de)(de)水(shui)蒸氣(qi)，從而降低(di)濕(shi)(shi)(shi)(shi)(shi)(shi)度。
