The hospital cares for over 275,000 children and their families each year in its sustainable buildings. The hospital generates 60% of its energy needs on site and generates renewable heat from its own plant, as well as capturing rainwater for its own use.
Green Cooling installed the CO2 refrigeration system for the main contractor, Laing O’Rourke. The specification needed a highly efficient refrigeration system for the kitchens and pharmacy, which met BREEAM standards.
Green Cooling's solution was a central CO2 refrigeration plant and two CO2 packaged units to delivery cooling and to transfer energy. They designed a multi-compressor packaged system to provide the main refrigeration load to ensure the high efficiency and 'contingency benefits' of both chilled and freezer needs.
The project took ten months to install, including building the cold storage, installing pipework, controls, refrigeration systems and plant. Demand for CO2 systems is growing as end users look for ways to lower their energy costs and provide sustainability at their sites.
Green Cooling’s Technical Director, Dave Blinkhorn said:
“We have now designed and installed many CO2 refrigeration systems within UK Hospitals. The sustainable credentials of the natural refrigerant CO2 rate very highly within a BREEAM assessment, plus the efficiency of a CO2 refrigeration systems also fits extremely well within applications where achieving a high level of energy efficiency is a priority”.
