空调加氟具体方法操作
Specific methods of air conditioning fluorination
1、开启空调
1. Turn on the air conditioner
加氟时可直接让空调在制冷模式下运转。因为制热状态下无法进行加氟操作，所以冬天加氟时，要用制热拔换向阀线的方法，强制空调进入制冷状态。
When adding fluorine, the air conditioner can be operated directly in refrigeration mode. Because it is impossible to add fluorine in the heating state, when adding fluorine in winter, it is necessary to use the method of heating and pulling the reversing valve line to force the air conditioner into the refrigeration state.
2、连接加氟设备
2. Connecting the fluorine adding equipment
空调正常启动后，从室外机低压阀侧的工艺口连接加氟设备。此过程中一定要排掉加氟管中的空气和脏物。
After the air conditioner starts normally, connect the fluorine adding equipment from the process port on the low-pressure valve side of the outdoor unit. In this process, the air and dirt in the fluorine adding tube must be discharged.
3、测压加氟
3. Piezometric fluorination
夏天观察低压压力，环境温度32摄氏度左右时，压力控制在0.45MP左右；
Observe the low pressure in summer. When the ambient temperature is about 32 ℃, the pressure is controlled at about 0.45mp;
冬天观察制热时的高压压力，压力稳定后控制在1.7MP左右。
In winter, observe the high pressure during heating, and control the pressure at about 1.7mp after the pressure is stable.
