style="text-indent:25px">在低層大氣中必須十分穩(wěn)定（也就是具有足夠長(zhǎng)的大氣壽命），使其能夠達(dá)到臭氧層。例如氫氯氟烴雪種HCF22和HCFC123，杜邦制冷劑,都有一個(gè)氯原子，能消耗臭氧，其大氣壽命分別為 12.1和14年，且氯原子相對(duì)活潑，杜邦制冷劑，能在低層大氣中發(fā)生分解，到達(dá)臭氧層的數(shù)量就不多。因此HCFC22和HCFC123破壞臭氧的能力比CFCs小得多。制冷劑分類：無機(jī)化合物、有機(jī)化合物、混合工質(zhì)。對(duì)空調(diào)行業(yè)規(guī)定了具體淘汰目標(biāo)，1）工商制冷：2003年停止CFC11/12新灌裝，2010年停止CFC11/12維修補(bǔ)充的再灌裝。2）家電：1999年40%新生產(chǎn)的冰箱冷柜的替代，杜邦制冷劑，2003年70%新生產(chǎn)的冰箱冷柜的替代，2005年100% 新生產(chǎn)的冰箱冷柜的替代。3）汽車空調(diào)：2002年停止新生產(chǎn)CFC12空調(diào)，2009年后在汽車空調(diào)上只允許使用回收的CFCs。到目前為止，我國(guó)*簽署了倫敦修正案，所以尚沒對(duì)HCFCs的淘汰作出承諾。制冷劑需具有優(yōu)良的熱物理性能。杜邦制冷劑</p><div

style="text-indent:25px">制冷劑不足的表現(xiàn)：①氣管閥門發(fā)干，用手觸摸沒有明顯的涼感。其原因是制冷劑不足導(dǎo)致蒸發(fā)器內(nèi)的沸騰終結(jié)點(diǎn)提前，使該閥的制冷劑過熱度增大，閥門的溫度升高，大于室外空氣的**溫度。②液管閥門結(jié)霜。其原因是制冷劑不足導(dǎo)致液管內(nèi)壓力下降，沸點(diǎn)降低，使閥門溫度低于冰點(diǎn)。③打開室內(nèi)機(jī)面板，取下過濾網(wǎng)，可發(fā)現(xiàn)部分蒸發(fā)器結(jié)露或結(jié)霜。其原因是由于制冷劑不足，*使部分蒸發(fā)器發(fā)生了沸騰吸熱，使制冷面積相應(yīng)減少；④室外機(jī)排風(fēng)沒有熱感。其原因是制冷劑不足導(dǎo)致冷凝壓力、冷凝溫度都降低，排風(fēng)溫度也降低。⑤排水軟管排水?dāng)鄶嗬m(xù)續(xù)或根本不排水。其原因是蒸發(fā)器制冷面積減少，結(jié)露面積也減少，凝結(jié)水量降低。⑥室外機(jī)氣、液閥門有油污，有油污就有泄漏。其原因是制冷劑與冷凍油有一定的互溶性，氟從漏點(diǎn)逸出后進(jìn)人大氣中，而油附著在漏點(diǎn)周圍。⑦測(cè)量空調(diào)器的工作電流小于額定電流。其原因是制冷劑不足而使壓縮機(jī)工作負(fù)荷減少，電流下降。⑧從室外機(jī)充氟口測(cè)量的壓力低于0.45Mpa。其原因是制冷劑不足導(dǎo)致了蒸發(fā)壓力下降。</p><p style="text-indent:25px">制冷劑的排放一般指直接把制冷劑排放到空氣中，排放時(shí)，周圍環(huán)境一定要通風(fēng)良好，不能接近明火，否則要產(chǎn)生有毒氣體。1，關(guān)閉歧管壓力計(jì)上的高，低壓手動(dòng)閥，連接其高，低壓軟管分別接在壓縮機(jī)高，低壓檢修閥上，中間管的自由端放在工作擦布上。2，慢慢打開高壓手動(dòng)閥，讓制冷劑從中間軟管上排出，閥門不能開得太大，否則壓縮機(jī)內(nèi)的冷凍潤(rùn)滑油會(huì)隨制冷劑替代。3，當(dāng)壓力表讀數(shù)降到0.35MPa以下時(shí)，再慢慢打開手動(dòng)閥，使制冷劑從高，低壓雙向同時(shí)排出。4，觀察壓力表讀數(shù)，隨著壓力下降，逐漸開大高，低壓手動(dòng)閥，直至高，低壓表的讀數(shù)指示為零。R404A是不破壞大氣臭氧層的環(huán)保制冷劑。</p><div

Substances）——對(duì)臭氧層有破壞、并且存在溫室效應(yīng)，因此在發(fā)達(dá)的各國(guó)和部分發(fā)展中的各國(guó)，已經(jīng)停止了在新空調(diào)、制冷設(shè)備上的初裝或舊設(shè)備上的再添加；中國(guó)2007年已停止了R12制冷劑的生產(chǎn)、以及在新制冷空調(diào)設(shè)備上的初裝。作為使用較較廣的中低溫制冷劑，R-12主要應(yīng)用于冰箱、冷柜、飲水機(jī)、汽車空調(diào)、商用空調(diào)、冷庫(kù)、商業(yè)制冷、冷凍冷凝機(jī)組等制冷設(shè)備中。二氟二氯甲烷同時(shí)還可應(yīng)用于氣霧推進(jìn)劑、物理發(fā)泡劑、配醫(yī)用消毒劑、殺蟲藥發(fā)射劑等。R134a對(duì)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(duì)鋅有輕微的作用。杜邦制冷劑</p><p
