Energy audit findings

Energy audit findings – the photograph above is a section of a damaged coil from an air conditioning unit. It is obviously a badly damaged, the aluminium fins have been stripped away, revealing the structure of the refrigeration tubing beneath, absolutely necessary for coolant-to-air heat exchange. However, since the air conditioning is still “technically working” it seems no repair is deemed necessary to restore the lost heat exchange area, and lost efficiency.

Specification Note: Actually this is a common problem, and easy to avoid – insist upon a heavy gauge, say 25mm x 25mm GI mesh over the exposed coil area to provide mechanical protection. With a large open grid, the mesh would not impede the air flow. It will protect the delicate fins from unintended damage.
