[恒溫恒濕試驗箱]恒溫恒濕試驗(yan)箱對濕度(du)系統的要求
恒溫恒濕(shi)(shi)(shi)(shi)試(shi)驗箱(xiang)除了(le)溫度之外,最重要(yao)的(de)就是濕(shi)(shi)(shi)(shi)度系統(tong)了(le),如果沒有濕(shi)(shi)(shi)(shi)度系統(tong),就將無法實現(xian)濕(shi)(shi)(shi)(shi)熱、恒濕(shi)(shi)(shi)(shi)等相關功能,以下我們仔細的(de)了(le)解下恒溫恒濕(shi)(shi)(shi)(shi)試(shi)驗箱(xiang)對濕(shi)(shi)(shi)(shi)度系統(tong)的(de)要(yao)求。
1、加(jia)(jia)濕系統分為淺(qian)槽(cao)加(jia)(jia)濕和鍋(guo)爐加(jia)(jia)濕,面積小、響應(ying)快、加(jia)(jia)濕效果精準(zhun)高效且維護(hu)(hu)檢修都很方便(bian),直接打開(kai)內箱的風蓋板即可(ke),鍋(guo)爐加(jia)(jia)濕由于放置在箱體后背,有部分管道夾在保溫層中,所以維護(hu)(hu)檢修都很不方便(bian)。
2、濕度(du)傳(chuan)感方式(shi)為分濕球紗(sha)布和(he)鉑電阻,鉑電阻無需紗(sha)布可(ke)自動進行溫濕度(du)整定(ding)傳(chuan)遞(di)濕度(du),但性價比不高,而濕球紗(sha)布成本實惠(hui)、更(geng)換方便、濕度(du)效果(guo)傳(chuan)遞(di)好,是業內較為通用的一種方式(shi)。
3、加水(shui)方(fang)式分為(wei)淺槽入(ru)口(kou)(kou)與(yu)抽屜式,兩種方(fang)式皆(jie)可,但淺槽入(ru)口(kou)(kou)相(xiang)對而言更加大(da)氣美(mei)觀。
4、加濕(shi)水(shui)(shui)(shui)分為純(chun)水(shui)(shui)(shui)和自(zi)(zi)來(lai)水(shui)(shui)(shui),雖然自(zi)(zi)來(lai)水(shui)(shui)(shui)在成本上較節約,但隱(yin)患較大,自(zi)(zi)來(lai)水(shui)(shui)(shui)中(zhong)有(you)很多的雜質可能會(hui)造成水(shui)(shui)(shui)路的堵塞,自(zi)(zi)來(lai)水(shui)(shui)(shui)中(zhong)的雜質形成污垢在水(shui)(shui)(shui)管內不易于(yu)清(qing)洗,水(shui)(shui)(shui)經水(shui)(shui)(shui)管吸附到(dao)被(bei)測(ce)樣(yang)品表面會(hui)形成二次污染,所以上海林頻儀器股份(fen)有(you)限(xian)公司(si)強烈建議(yi)用戶加濕(shi)水(shui)(shui)(shui)采用純(chun)水(shui)(shui)(shui)(純(chun)凈度(du)達到(dao)欽(qin)用標準即可),也可以采用純(chun)水(shui)(shui)(shui)裝(zhuang)置(zhi)(切記是化(hua)學過濾而不是物(wu)理過濾),一頭連接(jie)自(zi)(zi)來(lai)水(shui)(shui)(shui)龍(long)頭一頭連接(jie)到(dao)試驗箱入水(shui)(shui)(shui)口,自(zi)(zi)來(lai)水(shui)(shui)(shui)經純(chun)水(shui)(shui)(shui)裝(zhuang)置(zhi)進行化(hua)學過濾后可達到(dao)純(chun)水(shui)(shui)(shui)標準。

恒溫恒濕(shi)試(shi)驗箱濕(shi)度(du)系統的結構及原理
加濕方法(fa)一般采用蒸氣(qi)加濕法(fa),即將(jiang)常(chang)壓蒸氣(qi)直接注入(ru)試驗(yan)空間(jian)加濕。這種方法(fa)加濕能力(li)強,速度快,加濕控制靈(ling)敏,尤(you)其在降溫時容易實現強制加濕。
除(chu)濕(shi)(shi)(shi)方式(shi)有(you)兩(liang)種(zhong):冷卻除(chu)濕(shi)(shi)(shi)和干(gan)(gan)燥器除(chu)濕(shi)(shi)(shi)。冷卻除(chu)濕(shi)(shi)(shi)是將(jiang)空氣(qi)(qi)(qi)冷卻到(dao)露(lu)點溫度以下(xia),使大于(yu)飽和含濕(shi)(shi)(shi)量的(de)水氣(qi)(qi)(qi)凝結析出(chu),這樣就降低(di)了濕(shi)(shi)(shi)度。干(gan)(gan)燥器除(chu)濕(shi)(shi)(shi)是利用(yong)氣(qi)(qi)(qi)泵將(jiang)恒(heng)溫恒(heng)濕(shi)(shi)(shi)試(shi)驗箱(xiang)內的(de)空氣(qi)(qi)(qi)抽出(chu)并送入(ru)干(gan)(gan)燥器進(jin)(jin)行干(gan)(gan)燥,干(gan)(gan)燥完(wan)后(hou)又(you)送入(ru)試(shi)驗箱(xiang)內,如此所(suo)得循環進(jin)(jin)行除(chu)濕(shi)(shi)(shi)。現在大部份試(shi)驗箱(xiang)采用(yong)冷卻除(chu)濕(shi)(shi)(shi)方式(shi),后(hou)一種(zhong)除(chu)濕(shi)(shi)(shi)方法用(yong)于(yu)有(you)特殊要求的(de)場合,且(qie)費用(yong)較費。
