style="text-indent:25px">制冷劑充入量的準確判斷方法：測重量。在充注氟利昂時,事先準備一個小臺秤，將制冷劑鋼瓶放入一個容器中，再在容器中注入40℃以下的冷水(適用于空調器的低壓充注制冷劑蒸汽)。充注前記下鋼瓶、溫水及容器的重量，在充注過程中注意觀察指針。當鋼瓶內制冷劑的減少量等于所需要的充注量時可停止充注。測工作電流。用鉗型電流表測工作電流，制冷時，環(huán)境溫度35℃，所測得的工作電流與銘牌上電流相對應。溫度越高，電流相應增大，溫度越低電流相應減少。在風機正常、兩器散熱號的情況下按空調器工況測電流值作比較。</p><p

四氟乙烷，分子式CH2FCF3。由于R-134a屬于HFC類物質（非ODS物質Ozone-depleting Substances）——因此完全不破壞臭氧層，是當前世界絕大多數的各國認可并推薦使用的環(huán)保制冷劑，也是目前主流的環(huán)保制冷劑，較廣用于新制冷空調設備上的初裝和維修過程中的再添加。R-134a作為使用較較廣的中低溫環(huán)保制冷劑，由于HFC-134a

style="text-indent:25px">冰箱系統(tǒng)抽程控的時候把已經鎖上的高低壓閥門打開，開始進行正式的系統(tǒng)抽空工作，制冷系統(tǒng)如果已經被抽成程真空的時候關閉高低壓閥門再關閉真空泵。這個時候制冷系統(tǒng)處于真空狀態(tài)，就可以添加制冷劑了，把黃色管與真空本斷開街道制冷劑的并口上，打開制冷劑瓶子的氣門芯，黃色管里的空氣排凈后倒轉制冷劑瓶放好，打開高低壓閥門加入制冷劑。制冷劑加的差不多之后再把高低壓閥門關閉，放好制冷劑瓶，這樣冰箱制冷劑的添加就完成了。雖然冰箱制冷劑的添加看著簡單，其實細節(jié)方面容易出錯，所以還是建議大家找專業(yè)的人員來添加制冷劑，如果對自己有信心也可以自己完成冰箱制冷劑的添加。R134a

style="text-indent:25px">制冷劑冷卻法回收：使制冷劑蒸氣冷卻液化，可使用干冰等使制冷劑冷卻，液化后回收，此法適宜于干凈的制冷劑。冷卻法有一套**的冷凍循環(huán)系統(tǒng)，回收容器內的制冷劑在蒸發(fā)器中冷凝成液體。從汽車空調系統(tǒng)排出的制冷劑通過過濾干燥器，除去水分和雜質；通過分油器除去制冷劑中的潤滑油，進入回收容器。對于制冷劑純度要求不太嚴格的場合，被回收的制冷劑可重新加注到制冷系統(tǒng)。真空檢漏：用真空泵進行，真空度應達到0.1MPa，保持24h內真空度沒有明顯升高即可。抽真空用于抽出系統(tǒng)中殘留的氮氣、檢查系統(tǒng)有無泄漏以及使系統(tǒng)干燥。只有在系統(tǒng)抽真空后才能加注制冷劑。外觀檢漏：制冷劑泄漏部位往往會滲出冷凍潤滑油，若發(fā)現在某處有油污滲出，可進一步用清潔的白紙擦拭或用手直接觸摸檢查。如仍有油冒出，則可能有泄漏。蘇州杜邦制冷劑價格</p><p
