充分(fen)利用(yong)溫差(cha)大時(shi)，空(kong)氣(qi)中的水(shui)(shui)(shui)分(fen)易凝(ning)露的特點，產品(pin)內(nei)(nei)(nei)置凝(ning)水(shui)(shui)(shui)面上產生非(fei)(fei)常(chang)低的溫度(du)(能達(da)到- 35"C)，使空(kong)氣(qi)中水(shui)(shui)(shui)分(fen)冷(leng)凝(ning)在凝(ning)水(shui)(shui)(shui)面，并通(tong)過排(pai)(pai)水(shui)(shui)(shui)孔排(pai)(pai)出箱體外，保持電(dian)(dian)柜(ju)內(nei)(nei)(nei)部(bu)干燥。由于電(dian)(dian)柜(ju)內(nei)(nei)(nei)水(shui)(shui)(shui)分(fen)不(bu)斷減少排(pai)(pai)出箱外，柜(ju)內(nei)(nei)(nei)空(kong)氣(qi)中的濕度(du)顯(xian)著下降。即使環(huan)境濕度(du)變化，由于電(dian)(dian)柜(ju)內(nei)(nei)(nei)空(kong)氣(qi)中水(shui)(shui)(shui)分(fen)非(fei)(fei)常(chang)少，也(ye)不(bu)會(hui)再產生凝(ning)露，從根本上解決了電(dian)(dian)柜(ju)內(nei)(nei)(nei)濕度(du)困擾。
