UK: Dr Andy Pearson, group MD of Star Refrigeration, has won an ASHRAE award for design work on the world’s largest ammonia water-source heat pump.

Dr Pearson received ASHRAE’s Comfort Cooling Award for Project Excellence at the Society’s Winter Meeting in Las Vegas at the end of January.

The award is presented annually by ASHRAE’s Honours and Awards Committee to project designers and owners in recognition of innovative concepts, incorporation of new technologies and solutions to complex refrigeration problems.

Not for the first time, the winning project was the Drammen district heating and cooling scheme installed in 2011 which supplies the 65,000 inhabitants of the Norwegian city with 85% of their heat demand. The project has previously won a number of awards including the prestigious Rittinger Award at the 2014 International Heat Pump Conference.

Pearson’s 13MW water source district heating and cooling system extracts heat from the cold waters of a local river and boosting it up to 900C for heating on a massive scale.

Collecting the award, Pearson said, “I am honoured to accept this award from my fellow members of ASHRAE on behalf of all of the team at Star Refrigeration who worked hard to deliver Drammen’s vision of a community-wide, carbon free heating system.”

In its five years of uninterrupted operation, the plant is said to have delivered savings of €10m and 75,000 tonnes of carbon emissions to date.
