The maximum allowable extended length for the connecting pipes of the Mijia Air Conditioner Eco EGAT Label No.5 with 1 Star 9000BTU is 10 meters. Extending the pipes beyond this length is not recommended, as it can reduce the efficiency of the system and will impact the overall cooling performance of the air conditioner. Proper pipe length is essential to ensure stable operation and prevent potential strain on the compressor.
When the piping length exceeds 7 meters, it is necessary to add 15 grams of refrigerant per meter to maintain optimal cooling performance. This additional refrigerant helps ensure proper circulation and pressure within the system, allowing the air conditioner to operate efficiently even with extended pipe runs while preserving its long-term reliability and effectiveness.
