目前汽车空调几乎都以CFC12(R12)作为制冷剂,汽车空调的R12消耗量约占全球R12消耗量的28%左右。……美国,这个比例高达50%。由于汽车空调是安装在高速运动的物体——汽车上,工作条件恶劣;振动大,制冷剂容易泄漏,一般每隔二年(平均)汽车空调就要充注一次R12,即每隔二年汽车空调中的 At present, almost all of the automotive air conditioning to CFC12 (R12) as a refrigerant, automotive air conditioning R12 consumption accounts for about 28% of global R12 consumption. ......
