含义

制冷剂泄漏检测报警——系统检测到制冷剂泄漏量超过安全阈值,可能存在 R32/R290 易燃制冷剂泄漏风险。

常见原因

  1. 安装时扩口或焊接处存在微漏
  2. 管路长时间振动导致连接螺母松动
  3. 室外机管路被腐蚀性环境侵蚀
  4. 室内机蒸发器铜管磨损或腐蚀穿孔
  5. 加氟操作后阀芯未完全密封
  6. 温度变化引起管路接口热胀冷缩松动

自助排查

  1. 立即关闭空调电源,开窗通风
  2. 用肥皂水涂抹所有管路接口检查气泡
  3. 确认室外机截止阀阀帽是否拧紧
  4. 检查室内外连接管外观有无油迹或破损
  5. 切勿自行补充制冷剂,需联系专业人员检漏修复

English

Meaning

Refrigerant leakage detection alarm — the system detects refrigerant leakage exceeding the safety threshold. Risk exists with flammable refrigerants (R32/R290).

Common Causes

  1. Micron-level leaks at flared or brazed joints from installation
  2. Loosened connection nuts from prolonged pipe vibration
  3. Corrosion of outdoor unit piping in harsh environments
  4. Worn or corroded evaporator coil tubing in the indoor unit
  5. Service valve core not fully sealed after refrigerant recharge
  6. Thermal expansion/contraction loosening pipe connections

Self-Check Steps

  1. Immediately power off the air conditioner and ventilate the room
  2. Apply soapy water to all pipe connections and check for bubbles
  3. Verify the outdoor unit service valve caps are tightly closed
  4. Inspect the indoor-outdoor connecting pipes for oil stains or damage
  5. Do not attempt to recharge refrigerant yourself — contact a professional for leak detection and repair
