When the copper pipe of the fan coil unit ruptures, the following repair methods can be adopted:
Welding method: First, clean the damaged area, and then use welding tools to weld the damaged area to restore the sealing and integrity of the copper pipe. This method has a short repair time and good effect, but it requires a high level of sealing for copper pipes. The replacement method is also effective. If the damage is so severe that it cannot be repaired by welding, it is possible to consider replacing the damaged copper tube. During the replacement process, it is necessary to ensure that the material and size of the new copper pipe are the same as the original copper pipe to ensure the normal operation of the air conditioning system.
Adhesive method: suitable for small-scale copper tube damage. Firstly, determine the location of the copper tube rupture, and then use specialized film or tape for repair. This method is effective, but its lifespan may not be as good as welding and replacement methods.
Special circumstances where the pipeline connection ruptures. Repairs can be made by reinforcing pipeline connections, such as installing locking sleeves, opening and patching pipes, or using copper gaskets for reinforcement
Special circumstances of local rupture. Sealing method can be used for repair, such as drilling a small hole at the break and then sealing it with epoxy resin injection.
Tape wrapping method: suitable for emergency situations, use wide tape to wrap around the area near the rupture to temporarily stop water leakage. But this method is not a long-term solution
Using metal patches: For larger or more fractured areas or under greater pressure, metal patches can be used to cover the crack opening to prevent water leakage. Before taking any repair measures, it is important to immediately stop using the fan coil unit and shut down the system to prevent further rupture and further damage. In addition, for obvious leakage situations, it may be necessary to seek professional repair service providers or after-sales service providers for repair.
