低(di)溫恒溫水槽的(de)(de)常見(jian)故障應引起廣大用(yong)戶(hu)的(de)(de)關注

以(yi)前低(di)溫(wen)水箱水循(xun)環很正常，但(dan)現(xian)在(zai)發現(xian)噪音比以(yi)前大了很多，原因是什么？

理由：以前提到(dao)過(guo)水(shui)(shui)(shui)(shui)循(xun)環(huan)(huan)的(de)日常(chang)維護，這(zhe)個問題也與之有(you)(you)關(guan)。眾所(suo)周知，水(shui)(shui)(shui)(shui)里(li)有(you)(you)一些(xie)雜質。即使在(zai)(zai)(zai)蒸(zheng)餾水(shui)(shui)(shui)(shui)加入水(shui)(shui)(shui)(shui)箱(xiang)后(hou)，也無法(fa)保(bao)證完全(quan)沒有(you)(you)雜質。對于水(shui)(shui)(shui)(shui)循(xun)環(huan)(huan)，溫(wen)度一般設定在(zai)(zai)(zai)20℃，特別適合微(wei)生(sheng)(sheng)物的(de)生(sheng)(sheng)長繁殖。長時(shi)間后(hou)，這(zhe)些(xie)微(wei)生(sheng)(sheng)物會(hui)堵塞濾池的(de)水(shui)(shui)(shui)(shui)路(lu)，造成回水(shui)(shui)(shui)(shui)不(bu)暢，水(shui)(shui)(shui)(shui)泵會(hui)產生(sheng)(sheng)較大(da)的(de)噪(zao)聲。有(you)(you)時(shi)這(zhe)些(xie)微(wei)生(sheng)(sheng)物附著在(zai)(zai)(zai)換熱器表面，導(dao)致換熱效果和(he)冷卻能力較差。因此，要嚴格按(an)照說明書(shu)要求做(zuo)好(hao)日常(chang)維護保(bao)養，定期清洗低(di)(di)溫(wen)水(shui)(shui)(shui)(shui)箱(xiang)內(nei)罐，長期停用(yong)，保(bao)持(chi)罐內(nei)干燥。水(shui)(shui)(shui)(shui)循(xun)環(huan)(huan)好(hao)像漏(lou)水(shui)(shui)(shui)(shui)了。有(you)(you)時(shi)地(di)上有(you)(you)幾滴。水(shui)(shui)(shui)(shui)道(dao)有(you)(you)漏(lou)水(shui)(shui)(shui)(shui)嗎？一般來說，在(zai)(zai)(zai)正(zheng)常(chang)使用(yong)過(guo)程中，水(shui)(shui)(shui)(shui)路(lu)不(bu)會(hui)漏(lou)水(shui)(shui)(shui)(shui)。當環(huan)(huan)境溫(wen)度較高，空(kong)氣(qi)中相(xiang)對濕(shi)度過(guo)高時(shi)，水(shui)(shui)(shui)(shui)循(xun)環(huan)(huan)水(shui)(shui)(shui)(shui)路(lu)中的(de)水(shui)(shui)(shui)(shui)泵、水(shui)(shui)(shui)(shui)管接頭和(he)外水(shui)(shui)(shui)(shui)管處容易(yi)結露(lu)。積存更多(duo)露(lu)水(shui)(shui)(shui)(shui)后(hou)會(hui)滴落到(dao)地(di)上，所(suo)以不(bu)用(yong)擔心低(di)(di)溫(wen)水(shui)(shui)(shui)(shui)箱(xiang)就(jiu)是(shi)漏(lou)水(shui)(shui)(shui)(shui)的(de)地(di)方。如(ru)果你在(zai)(zai)(zai)意這(zhe)個，打(da)開空(kong)調降低(di)(di)室溫(wen)或除濕(shi)可以避免結露(lu)。

低(di)溫(wen)恒溫(wen)水(shui)槽里的水(shui)循(xun)環使用一年多是(shi)正(zheng)常的，但現在(zai)冷卻速度似乎越(yue)來越(yue)慢(man)，溫(wen)度越(yue)高越(yue)明顯？

理由：水(shui)循(xun)環很簡單，但定期維護(hu)保(bao)養工(gong)作不容(rong)忽視。有(you)許多看似故障的(de)問題，都是由于(yu)沒有(you)進行定期維護(hu)而引起的(de)。水(shui)循(xun)環的(de)電(dian)力和制冷(leng)(leng)劑從負載(zai)中(zhong)帶走的(de)熱量(liang)需要從前(qian)通(tong)風(feng)(feng)罩的(de)散(san)熱器中(zhong)排出(chu)。如果前(qian)通(tong)風(feng)(feng)罩內滿是灰塵和柳絮，會阻(zu)礙散(san)熱，制冷(leng)(leng)效果也會大打折扣。一般來說，在正常使用條件下，制冷(leng)(leng)量(liang)的(de)下降是由于(yu)通(tong)風(feng)(feng)散(san)熱效果差或(huo)環境溫度過高造成的(de)。
