什么情况下要对空调加氟
Under what circumstances should the air conditioner be fluorinated
1、使用超过5年以上的（任何一台分体式空调机都会自然泄漏氟立昂）；
1. Used for more than 5 years (any split air conditioner will naturally leak Freon);
2、多次移机的（空调移机排空时会消耗部分氟立昂）；
2. Many times of relocation (some Freon will be consumed when the air conditioner is relocated and emptied);
3、夏天外机连接点的粗管裸露处（即低压管）不结露或不凉的；
3. In summer, the exposed part of the thick pipe (i.e. the low-pressure pipe) at the connection point of the external machine does not condense or cool;
4、夏天外机风扇排风不热的；
4. In summer, the exhaust of the external fan is not hot;
5、夏天回气压力（粗管）低于0.4兆帕的；
5. In summer, the return gas pressure (coarse pipe) is lower than 0.4 MPa;
6、压缩机运转电流小于铭牌标注正常值的；
6. The operating current of the compressor is less than the normal value marked on the nameplate;
7、夏季高压管（细管）结霜的；
7. High pressure pipe (thin pipe) frosting in summer;
8、夏季空调内机结冰或吹
框格护坡模具 箱体护坡模具 华尔街铜牛 电阻柜 接地电阻柜 电缆保护接地箱 隔离墩模具 化粪池模具雾的（有时候还伴有内机漏水）；
8. Ice or fog blowing in the air conditioner in summer (sometimes accompanied by water leakage in the air conditioner);
9、冬季手摸外机铜管接口处粗管不烫手的；
9. In winter, it is not hot to touch the thick pipe at the copper pipe interface of the external machine;
10、空调有泄漏点的；
10. Air conditioners with leakage points;
11、空调开机后十几分钟就停机的（低压保护或过热保护）。
11. The air conditioner shuts down more than ten minutes after starting up (low-voltage protection or overheat protection).
