为什么要加氟
Why add fluorine
氟立昂是空调制冷系统中传递热量的媒介。没有它，热量就无法进行有效的交换。空调也不可能制冷或制热。所以一旦空调缺氟，外在表现出制冷（热）效果差、不制冷（热）、保护性停机、室内机漏水（有时候会喷水）、内机蒸发器结冰等。而更有表面看不到的问题--减少空调的使用寿命、浪费电力、损害空调压缩机。所以要想正常使用空调，必须要有足够的氟立昂。
Freon is the medium of heat transfer in air conditioning and refrigeration system. Without it, heat cannot be exchanged effectively. Air conditioning is also impossible to cool or heat. Therefore, once the air conditioner is lack of fluorine, it shows poor cooling (heat) effect, no cooling (heat), protective shutdown, indoor unit water leakage (sometimes water spray), internal unit evaporator ice, etc. And there are more problems that can't be seen on the surface -- reducing the service life of air conditioning, wasting power, damaging the air conditioning compressor. So if you want to use air conditioning normally, you must have enough Freon.
