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(nèi)的制冷劑在蒸發(fā)器中冷凝成液體。從汽車空調(diào)系統(tǒng)排出的制冷劑通過過濾干燥器，除去水分和雜質(zhì)；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(yán)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(yīng)達(dá)到0.1MPa，保持24h內(nèi)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(xiàn)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。江蘇冰龍制冷劑多少錢其他化學(xué)制品包括化學(xué)氰（石油醚和石腦油）、二氧化硫(R-764)和甲醚，曾被作為蒸氣壓縮用制冷劑。</p><div

style="text-indent:25px">R-134a制冷劑應(yīng)用領(lǐng)域包括：冰箱、冷柜、飲水機、汽車空調(diào)、中央空調(diào)、除濕機、冷庫、商業(yè)制冷、冰水機、冰淇淋機、冷凍冷凝機組等制冷設(shè)備中，同時還可應(yīng)用于氣霧推進劑、醫(yī)用氣霧劑、殺蟲藥拋射劑、聚合物（塑料）物理發(fā)泡劑，以及鎂合金保護氣體等。雖然R134a制冷劑是新裝制冷設(shè)備上替代氟利昂R12較普遍的選擇，但是由于R134a與R12物化性能、理論循環(huán)性能以及壓縮機用油等均不相同，因此對于初裝為R12制冷劑的制冷設(shè)備的售后維修，如果需要再添加或更換制冷劑，仍然只能添加R12，通常不能直接以R134a替代R12（也就是說通常不可以進行換血式的替換）。</p><p style="text-indent:25px">在氣體壓縮式制冷機中，使用氣體制冷劑，如空氣、氫氣、氦氣等，這些氣體在制冷循環(huán)中始終為氣態(tài)；在吸收式制冷機中，使用由吸收劑和制冷劑組成的二元溶液作為工質(zhì)，如氨和水、溴化鋰（分子式：LiBr。白色立方晶系結(jié)晶或粒狀粉末，極易溶于水）和水等；蒸汽噴射式制冷機用水作為制冷劑。制冷劑的主要技術(shù)指標(biāo)有飽和蒸氣壓強、比熱、粘度、導(dǎo)熱系數(shù)、表面張力等。1960年以后，人們對非共沸混合工質(zhì)的應(yīng)用進行了大量的試驗研究，并已將其用于天然氣的液化和分離等方面。制冷劑需具有優(yōu)良的熱物理性能。</p><div

style="text-indent:25px">制冷劑飽和蒸氣的溫度與壓力呈對應(yīng)關(guān)系，若已知制冷劑的蒸發(fā)溫度即可查出相對應(yīng)的蒸發(fā)壓力。此壓力的表壓值由高、低壓壓力表顯示出來。因此，根據(jù)安裝在系統(tǒng)上壓力表的壓力值即可判斷制冷劑的充注量是否宜適。例如：空調(diào)器的蒸發(fā)溫度為7.2℃，冷凝溫度為54.5℃使用R22。查R22的飽和溫度與飽和壓力對應(yīng)表，以確定其蒸發(fā)壓力值和冷凝壓力值。查表可知：R22在7.2℃時相應(yīng)相對壓力值為0.53Mpa(5.3kg/cm2)和54.5℃時的相應(yīng)相對壓力值為2.11Mpa(21.1kg/cm2)，將此壓力換算為表壓值即可。用高、低壓壓力表或復(fù)合式壓力表測試充氟中的制冷系統(tǒng)，若高、低壓力表表壓值符合上述范圍即表明制冷劑的充注量合適;若高、低壓壓力均低則表明充入量不夠;若高、低壓壓力均高，則表明充入量過多。壓力測定法較為簡便，在維修時經(jīng)常作用，但是缺點是比較粗，準(zhǔn)確度不高。R134a對鋼、鐵、銅、鋁等金屬未發(fā)現(xiàn)有相互制冷劑化學(xué)反應(yīng)的現(xiàn)象，*對鋅有輕微的作用。江蘇冰龍制冷劑多少錢</p><p
