A properly installed and maintained aircon copper pipe system can last for 20-30 years or even longer. However, lifespan is influenced by several factors, including water quality, refrigerant type, and environmental conditions. Regular inspections and preventative maintenance, such as flushing the system and checking for leaks, are crucial for maximizing longevity. Corrosive environments may shorten the lifespan.
Leaks can occur due to corrosion, especially in areas with high humidity or exposure to salt air. Mechanical stress from vibrations or improper installation can also cause cracks. Furthermore, incompatibility with certain refrigerants, or the formation of formicary corrosion due to contaminants in the refrigerant, can lead to leaks. Proper brazing techniques and material selection are vital.
Not all copper alloys are compatible with all refrigerants. Newer, more environmentally friendly refrigerants can be more corrosive. It’s crucial to select a copper alloy specifically designed for use with the refrigerant being employed. Consulting with a qualified HVACR engineer or referring to industry standards is essential to ensure compatibility and prevent corrosion.
Proper brazing is critical for leak-free joints. Ensure the tubing is thoroughly cleaned and deoxidized before applying flux.
