后成型的焊縫檢測級別、比例與設(shè)備殼體相同，高了浪費(fèi)。舉例：假如設(shè)備殼體是2%檢測，III合格。那封頭拼接焊縫和后焊縫也是III合格，焊接接頭系數(shù)為.85；假如設(shè)備殼體是1%檢測，II合格。那封頭拼接焊縫和后焊縫也是II合格，焊接接頭系數(shù)為1。所以封頭拼接雖然1%檢測，但合格級別不一樣，隨設(shè)備殼體走。但要注意工藝制造過程：正確的做法是：下料（劃線）-小板拼成大板-成型-無損檢測如果未成型之前做檢測是不對的，保證不了成型之后還合格。

冷凝器的制冷劑液體應(yīng)暢通無阻地流入貯液器內(nèi)，這樣就可以充分利用冷凝器的冷卻面積。另一方面，當(dāng)蒸發(fā)器的熱負(fù)荷變化時，制冷劑液體的需要量也隨之變化，那時，貯液器便起到調(diào)劑和貯存制冷劑的作用。對于小型制冷裝置系統(tǒng)，往往不裝貯液器，而是利用冷凝器來調(diào)劑和貯存制冷劑。干燥過濾器：在制冷循環(huán)中必須預(yù)防水分和污物（油污、鐵屑、銅屑）等進(jìn)入，水分的來源主要是新添加的制冷劑和潤滑油所含的微量水份，或由于檢修系統(tǒng)時空氣進(jìn)入而帶來的水分。
