Excalibur reduce airport energy consumption by 4,000,000 Kwh
Following a successful pilot installation of Liquid Pressure Amplification and inverter control of condenser fans to two York chillers at Manchester airport’s Olympia House, Excalibur were invited to undertake a detailed survey of all chillers at the airport and provide a report to show the potential to improve energy efficiency.
The results of the pilot made a clear case for a larger scale project and Excalibur were engaged to undertake the installation of Liquid Pressure Amplification and inverter control of condenser fans, as well as the replacement of badly corroded condensers on 20 chillers located around the airport.
With several of the chillers still operating on the ozone-depleting refrigerant R22, the airport also contracted Excalibur to complete a refrigerant change, All R22 was removed and replaced with the ozone friendly drop in replacement R422d, and recommissioned
Excalibur have a long history of undertaking this kind of project, having completed similar work at Heathrow, Stansted, Birmingham, Edinburgh and Glasgow airports and are well used to the security implications of working airside.
The project was completed with minimum downtime, the re-lifing exercise of replacing corroded condensers and ozone depleting refrigerants avoided the costly replacement of chillers. Post project monitoring showed energy consumption to have been reduced by 4,000,000 KWh / year, achieving an ROI of less than 3 years
