維修的空調必須符合其使用條件及安裝標準。
1. The air conditioner repaired must meet its service conditions and installation standards.
2.維修的空調控制系統及執行元件必須正常；管路系統必須已有效排除空氣、水分、阻塞、泄漏點等情況；過濾網、內外熱交換器應清潔，通風良好。
2. The air conditioning control system and actuator must be normal; The
pipeline system must have effectively eliminated air, moisture,
blockage, leakage point, etc; The filter screen and internal and
external heat exchangers shall be clean and well ventilated.
3.維修工具及材料必須合格。
3. Maintenance tools and materials must be qualified.
4.嚴格按加氟工藝*作。
4. Strictly follow the fluorination process *.
二、準確加氟的依據和方法
2、 Basis and method of accurate fluorination
1.定量加氟：在三通截止閥工藝口連接好三通閥、壓力表、加氟軟管、氟瓶或真空泵等。放氟抽真空后，開始慢慢加氟。用臺秤等較精確的
型槽模具 一次性止血帶 保定水處理設備 一次性止血帶 保定空壓機 北京真空泵計量工具稱重，當氟瓶內氟的減少量等于空調銘牌上的標準加氟量時，關閉氟瓶閥門。
1. Quantitative fluorination: connect the three-way valve, pressure
gauge, fluorination hose, fluorine bottle or vacuum pump at the process
port of the three-way stop valve. After defluorination and vacuum
pumping, start to add fluorine slowly. Weigh with more accurate
measuring tools such as platform scale. When the reduction of fluorine
in the fluorine bottle is equal to the standard fluorine addition on the
nameplate of the air conditioner, close the valve of the fluorine
bottl
