制冷(leng)(leng)(leng)(leng)系(xi)統(tong)中有(you)(you)(you)了(le)空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)可以這(zhe)樣處理(li):關閉制冷(leng)(leng)(leng)(leng)系(xi)統(tong)冷(leng)(leng)(leng)(leng)凝器(qi)或儲液器(qi)上(shang)的(de)(de)閥門(men)，然后啟動(dong)壓(ya)(ya)(ya)縮(suo)機(ji)(ji)運(yun)行(xing)一(yi)段時間，觀(guan)察(cha)壓(ya)(ya)(ya)縮(suo)機(ji)(ji)的(de)(de)低壓(ya)(ya)(ya)壓(ya)(ya)(ya)力表值，當表壓(ya)(ya)(ya)達(da)到(dao)“0”時，停(ting)止(zhi)壓(ya)(ya)(ya)縮(suo)機(ji)(ji)的(de)(de)運(yun)行(xing)，打開冷(leng)(leng)(leng)(leng)凝器(qi)頂部(bu)的(de)(de)放(fang)氣(qi)(qi)(qi)(qi)(qi)(qi)閥(若(ruo)冷(leng)(leng)(leng)(leng)凝器(qi)的(de)(de)位置比壓(ya)(ya)(ya)縮(suo)機(ji)(ji)低，則(ze)選擇開啟壓(ya)(ya)(ya)縮(suo)機(ji)(ji)排氣(qi)(qi)(qi)(qi)(qi)(qi)三通截(jie)止(zhi)閥的(de)(de)多(duo)用(yong)通道(dao))，讓氣(qi)(qi)(qi)(qi)(qi)(qi)體流出(chu)(chu)幾(ji)秒鐘再關。幾(ji)分(fen)鐘后重復這(zhe)一(yi)操(cao)作。因為空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)比制冷(leng)(leng)(leng)(leng)劑輕(qing)(qing)，靜置后聚(ju)在容器(qi)頂部(bu)，分(fen)次操(cao)作可減(jian)(jian)輕(qing)(qing)擾動(dong)，減(jian)(jian)少制冷(leng)(leng)(leng)(leng)劑的(de)(de)流失。每次放(fang)氣(qi)(qi)(qi)(qi)(qi)(qi)后注(zhu)意(yi)排出(chu)(chu)壓(ya)(ya)(ya)力表，該壓(ya)(ya)(ya)力應有(you)(you)(you)所下降(jiang)(jiang)，如(ru)降(jiang)(jiang)后又漸漸回升到(dao)放(fang)氣(qi)(qi)(qi)(qi)(qi)(qi)前數值，則(ze)表明放(fang)掉(diao)的(de)(de)已是(shi)制冷(leng)(leng)(leng)(leng)劑，應結束放(fang)氣(qi)(qi)(qi)(qi)(qi)(qi)。也(ye)可以在放(fang)氣(qi)(qi)(qi)(qi)(qi)(qi)時，用(yong)手(shou)觸摸氣(qi)(qi)(qi)(qi)(qi)(qi)流，若(ruo)是(shi)冷(leng)(leng)(leng)(leng)風就繼續放(fang)，如(ru)有(you)(you)(you)涼(liang)氣(qi)(qi)(qi)(qi)(qi)(qi)感(gan)(gan)覺，說明有(you)(you)(you)制冷(leng)(leng)(leng)(leng)劑跑出(chu)(chu)，應堵上(shang)堵頭(tou)。這(zhe)里需要(yao)指出(chu)(chu)，氟利昂冷(leng)(leng)(leng)(leng)凝器(qi)放(fang)空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)時，氟氣(qi)(qi)(qi)(qi)(qi)(qi)跑出(chu)(chu)往往是(shi)過熱氣(qi)(qi)(qi)(qi)(qi)(qi)體，不(bu)一(yi)定會(hui)有(you)(you)(you)涼(liang)的(de)(de)感(gan)(gan)覺。因此(ci)，氟利昂系(xi)統(tong)放(fang)空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)時，應首先對系(xi)統(tong)是(shi)否有(you)(you)(you)空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)作出(chu)(chu)明確(que)判(pan)斷，確(que)有(you)(you)(you)空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)時才進行(xing)放(fang)空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)，否則(ze)就會(hui)浪費氟利昂。
