The maximum pipe length for a 1-ton split air conditioning system can vary depending on the specific manufacturer and model of the AC unit. However, as a general guideline, the typical maximum pipe length for a 1-ton split AC system is around 10 to 15 meters (approximately 33 to 49 feet).
The pipe length refers to the total combined length of both the liquid line (also known as the high-pressure line) and the suction line (also known as the low-pressure line). The liquid line carries refrigerant from the outdoor condenser unit to the indoor evaporator unit, while the suction line carries refrigerant back from the indoor unit to the outdoor unit for the cooling process.
It's essential to follow the manufacturer's guidelines and recommendations regarding the maximum pipe length for the specific model of the AC unit. Installing a system with excessively long pipe lengths can result in decreased cooling efficiency, increased strain on the compressor, and potential performance issues.
If you need to install an air conditioning system with longer pipe lengths due to specific installation requirements, consult with a qualified HVAC technician or the manufacturer to ensure proper installation and optimal system performance. They can provide guidance on any necessary adjustments or considerations for longer pipe runs.
