Facilities management at the head office of one of the UK’s leading retailers wanted to improve HVAC energy efficiency and increase cooling performance.
Our Ultraviolet Solutions team was commissioned to perform a trial installation. We fitted our Total Coil Disinfection within one of the building’s air handling units, with a view to proving the effectiveness of the technology for improving HVAC efficiency.
U values measure a cooling coil’s thermal performance. Prior to the installation of Total Coil Disinfection, a U value of 5,473 w/m2K was recorded from the client’s cooling coil. The U value after fitting Total Coil Disinfection was 12,462 – an improvement of 127.7%.
Calculated pro rata, the client’s annual chilled water flow was reduced from 32,010 to 16,399 tonnes (49%).
After taking into account supply, installation and running costs of Total Coil Disinfection, our client would enjoy net annual savings of £3,356, with return on investment achieved in two years and two months.
