冷柜使用時間長之后,開門費勁是怎么回事。

綠締冷柜 / 2021-10-23 / 閱讀: / 點贊: 給我點贊

冷柜使用一段時間后,開門時特別費勁,請問是什么原因?不知道跟門封條老化有沒有關系?門封條時間長了黏度會變大,同時鉸鏈不合理保養也會生銹,這是不是也有因素?

 

接下來我就帶你們了解一下。

冷柜制冷后箱內溫度比較低,造成內外壓力差,一般廠家會有兩種方式來避免此種情況。臥式的冷柜,門封條上會有個小孔,用來平衡氣壓。立式的就比較難處理了,之前一直沒有看到有好的辦法,近期發現商場有一款冷凍柜,立式冷凍柜使用的助力手把,,可以向里面一頂,可以輕松開門,很巧妙,用機械原理克服了這個困難。

 

簡單來說:冷柜制冷后箱內溫度比較低,內外壓力差,造成開門格外費力。

 

 

開門費勁,與門封條密封不好沒關系。相反,正是密封太好時,箱內的空間由于制冷降溫收縮,壓力減小,造成內外壓差,外面的空氣壓力大,門體受力,才會打不開。主要是開關門后較短的時間內,內外壓力差較大,難以打開。

 

一般情況下,廠家都會設有內外氣壓平衡的結構,只是方式不同,平衡的效果有差異。
