When does air conditioning need fluorine?
1、使用超过5年以上的;
1. Use for more than 5 years;
2、多次移机的(空调移机排空时会消耗部分氟立昂);
2. The air conditioner will consume part of Freon when it is moved for several times;
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 (i.e. the low-pressure pipe) of the rough 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 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 running 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. Frosting of high pressure tubes (tubules) in summer;
8、夏季空调内机结冰或吹雾的(有时候还伴有内机漏水);
8. In summer, the air conditioner is iced or fogged (sometimes accompanied by water leakage of the air conditioner);
9、冬季手摸外机铜管接口处粗管不烫手的;
9. In winter, the rough pipe at the copper pipe interface of the external machine is not hot;
10、空调有泄漏点的;
10. Air conditioner has leakage point;
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 is shut down (low pressure protection or overheat protection) within ten minutes after it is turned on.
