Sustainability Index Score: 95%
Amount of Carbon Saved: 81.335 kg CO₂
Background
A client in North Yorkshire experienced a power failure that disabled one of their air conditioning units in the server room. Given the critical nature of maintaining a stable environment in server rooms, it was essential that the machine be repaired as swiftly as possible to avoid potential damage to sensitive equipment.
To ensure an immediate response, Lunar Refrigeration Ltd conducted a thorough inspection of the affected unit, identifying a damaged Noise Filter Board. The board showed multiple broken components, including a damaged Varistor, Bridge Rectifier, and Glass Fuse.
Problem Identification
Our inspection revealed that the power surge had caused significant damage to the Noise Filter Board. The broken Varistor, Bridge Rectifier, and Glass Fuse were preventing the board from operating correctly, resulting in the air conditioner being unable to function.
Solution Implementation
Rather than waiting for a new board to be sourced and shipped, Lunar Refrigeration Ltd carried out an in-depth component-level repair of the existing board to minimise downtime. The following steps were taken:
- Replacement of the Varistor: The damaged Varistor was removed and replaced with a new component to protect the circuit from future power surges.
- Repair of the Bridge Rectifier: The broken Bridge Rectifier was replaced, ensuring the board could correctly convert AC to DC power.
- Replacement of the Glass Fuse: A new Glass Fuse was installed to safeguard the circuit and prevent further damage.
Repaired Board
After all components were replaced, the board was tested rigorously to confirm functionality and stability before being reinstalled in the outdoor unit.
Outcome
By carrying out a component-level repair rather than waiting for a replacement board, Lunar Refrigeration Ltd was able to restore the air conditioning unit to full functionality in a much shorter time frame. This swift intervention ensured that the server room remained within its required temperature parameters, preventing any further risk to the client’s sensitive equipment.
