Introduction: Telecom rooms in major grid points on the transmission network contain sensitive electronic equipment e.g. Cisco routers. Recent installations have shown this equipment to be sensitive to temperatures above 40°C.

This project will develop, test and install innovative low carbon solutions to cool telecom equipment and telecom rooms without the need for air conditioning. Directed airflows, filterless centrifugal fans and the improvement of mass flow rates through the RFI cabinets will form the technical innovation required. This is understood to be the first such energy saving initiative using these technologies in equipment rooms and will avoid over 50% of the costs noted above.

Objectives: Currently 10 out of 19 sites utilise traditional air conditioning. It is proposed to trial 4energys cabinet cooling solution in all our 19 existing sites. The whole room cooling solution is to be trialled on 3 sites, if successful could be deployed into all 130 transmission substations.
