為什么要除霜?結(jié)霜主要會(huì)導(dǎo)致以下問題:總結(jié)一點(diǎn)就是:結(jié)霜會(huì)導(dǎo)致蒸發(fā)器換熱不好,直接降低了冷機(jī)的冷量。結(jié)霜前:結(jié)霜后:多久需要做一次除霜,每次除霜多長(zhǎng)時(shí)間?1)、這要考慮所儲(chǔ)藏產(chǎn)品的種類和濕度、人員在冷藏室內(nèi)走動(dòng)的頻度、每天開門的次數(shù)、透風(fēng)情況、空氣濕度等因素。、必須盡可能頻繁地除霜,而且要盡早,以免為時(shí)太遲。、如除霜時(shí)間太短,未能將冰全部融化,則會(huì)產(chǎn)生更多的冰。除霜的幾種方式:目前主流除霜的幾種方式:自然除霜熱空氣、水沖霜;電加熱除霜熱氣旁通除霜自然除霜機(jī)理與過程:包括空氣除霜與水沖霜空氣除霜:利用蒸發(fā)器的熱空氣(高于4℃),開啟蒸發(fā)器風(fēng)機(jī)使熱空氣循環(huán),將蒸發(fā)器的霜除掉;除霜過程:開始除霜壓縮機(jī)停機(jī)蒸發(fā)側(cè)風(fēng)機(jī)繼續(xù)運(yùn)轉(zhuǎn)熱空氣流過蒸發(fā)器化霜除霜完畢壓縮機(jī)啟動(dòng)水沖霜:蒸發(fā)器頂部位置增加集水槽,槽底開圓孔;自來水進(jìn)入集水槽之后銅管圓孔,均勻由上至下流通蒸發(fā)器翅片,一方面通過水的重力將霜沖洗干凈,一方面水的溫度比較高,將霜化成水一起流走。
