Leading UK hospital embraces sustainable CO2 refrigeration

Alder Hey in the Park

Lancashire cooling and refrigeration specialist GreenCooling has just completed the design and installation of a sustainable CO2 refrigeration system at the brand new park development at Alder Hey Children’s Hospital.

The project included walk-in refrigerated storage for the main kitchens supplied by a  a centralised high efficiency CO2 refrigeration system which also supports refrigerated storage for pharmacy use.

Alder Hey is one of Europe’s busiest children’s hospitals – caring for over 275,000 young people and their families every year and has created a brand new sustainable hospital.

Alder Hey is set to be one of the most sustainable hospitals ever built with 60% of its energy-generated onsite, rain water-capture systems and a renewable heating plant.

This sustainable focus also reaches into the area of refrigeration with the latest CO2 refrigeration technology being designed and installed by Green Cooling directly for the main contractor Laing O’Rourke.

A high specification food service refrigeration system tied with a pharmacy refrigeration system was required in order to match both the projects sustainability demands and also to meet the demands of the BREEAM environmental assessment.

The refrigeration design was relatively complex and required a complete system based approach in terms of both cooling delivery and energy transfer via a central CO2 refrigeration plant and two individual CO2 packaged units.

A multi-compressor packaged system was configured to satisfy the main refrigeration load in order to provide both efficiency and contingency benefits within both chilled and freezer outputs.

This project typifies how refrigeration is now quickly moving forward into a new era of sustainability and efficiency by utilising CO2, which is one of our oldest natural refrigerants to create cooling systems that meet the highest environmental standards that are demanded in 2015.

Dave Blinkhorn Green Cooling’s Technical Director commented: “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.”
