style="text-indent:25px">氨的比重和粘度小，放熱系數(shù)高，價格便宜，易于獲得。但是，氨有較強的毒性和可燃性。若以容積計，當空氣中氨的含量達到0.5%～0.6%時，人在其中停留半個小時即可中毒，達到11%～13%時即可點燃，達到16%時遇明火就會。因此，氨制冷機房必須注意通風排氣，并需經(jīng)常冰箱排除系統(tǒng)中的空氣及其它不凝性氣體?？偵纤?，氨作為制冷劑的優(yōu)點是：易于獲得、價格低廉、壓力適中、單位制冷量大、放熱系數(shù)高、幾乎不溶解于油、流動阻力小，泄漏時易發(fā)現(xiàn)。其缺點是：有刺激性臭味、有毒、可以燃燒和，對銅及銅合金有腐蝕作用。</p><p style="text-indent:25px">壓縮法回收：用壓縮的方法將制冷劑蒸發(fā)變成液體：從空調系統(tǒng)排出的制冷劑通過過濾干燥器，除去水分和雜質，受吸氣壓力調節(jié)控制閥，部分液態(tài)制冷劑存留在儲液罐中，氣態(tài)制冷劑進入壓縮機被壓縮成高溫高壓氣體，通過分油器時，與制冷劑混合的冷凍潤滑油被分離出來，流回壓縮機，制冷劑則進入冷凝器被冷卻，通過氣液分離器，被冷凝的液態(tài)制冷劑流到回收容器，回收容器中的部分氣態(tài)制冷劑會通過毛細管被壓縮機吸入。抽真空是為了排除制冷系統(tǒng)內(nèi)的空氣和水氣，是空調維修中一項極為重要的程序。因為對制冷系統(tǒng)進行維修或更換元件時，空氣會進入系統(tǒng)，且空氣中含有一定量的水蒸氣(濕空氣)。系統(tǒng)抽真空時，時間越長，系統(tǒng)內(nèi)殘余的水分就越少。為較大限度地將系統(tǒng)內(nèi)的空氣及濕氣抽出，必須采用重復抽真空法，即首先次抽真空完畢后，再連續(xù)抽30min以上。R410A制冷劑無色氣體，貯存在鋼瓶內(nèi)是被壓縮的液化氣體。</p><div
