Addenbrooke’s energy costs with new chiller installation
Air conditioning, chiller and compressor services company, LH-plc, has completed a major chiller replacement project at Addenbrooke’s Treatment Centre in Cambridge, part of the Addenbrooke’s Hospital complex, a world-renowned teaching hospital and internationally known centre of medical excellence.
A
s a result of careful chiller selection and high-quality installation, the project is saving the treatment centre more than a
third on energy costs. The original chiller, one of three in the
treatment centre, had been in place since the early 2000s and had come to the end of its working life. The client - engineering and construction group Bouygues - wanted a like- for-like replacement. Chiller selection was, however, made particularly challenging because the technology has moved on considerably in the last two decades, so a directly equivalent replacement was not possible. LH-plc off ered four potential alternative chillers and then narrowed the selection down to an 800kW Daikin chiller based mainly on value for money, physical size, weight, and cooling capacity. LH is a Daikin D1 business partner which
allows it to off er the best price, a free-of-charge extended warranty, and dedicated technical support.
Paul King, project sales manager at LH-
plc, explains: “Selecting the right supply and installation partner is critical in any contract, but the two most important factors to consider are specifying the correct chiller and ensuring excellent installation. Without these, the chiller will not operate as it should, and performance will be adversely aff ected.” A particular challenge in this contract was the need to work with Cambridge City Airport

for cranage permissions. King says: “Using cranes often entails a partial road closure, and/ or permits, or permissions to crane lift from a certain area. And, in the case of this project, traffi c management was required. Cambridge City Airport is just four miles away and the crane
was positioned directly in line with the approach fl ight path. The airport also needed to know about the crane in case of air ambulance traffi c. “This meant we had to communicate with the right people at the airport to gain permission to complete this project. Having done this, we
