准备工作：确保车辆停放在通风处，发动机熄火，空调系统关闭。检查空调管路是否有泄漏，必要时先进行检漏和维修。
连接设备：将制冷剂罐倒置，通过加注软管连接至汽车空调低压侧加注口（通常位于发动机舱内，标有“L”或“LOW”）。
加注制冷剂：启动发动机，打开空调至最大制冷模式（A/C 开启，风量最大），让压缩机运转。缓慢打开制冷剂罐阀门，观察压力表读数，一般加注至低压侧压力为 2.5–3.5 bar（具体以车辆说明书为准）。
完成加注：加注完成后，关闭制冷剂罐阀门，断开连接，检查空调出风口温度，确认制冷效果恢复正常。
注意事项：加注过程中避免制冷剂直接接触皮肤或眼睛，如不慎接触，立即用大量清水冲洗并就医。
