Carrier chillers operating on lower GWP refrigerant R32 have been selected to provide energy-efficient cooling for three world-renowned medical science laboratories at Oxford University. 

Four Carrier AquaSnap 30RBP air-cooled scroll chillers with Greenspeed intelligence have been installed at the Henry Wellcome Building for Genomic Medicine, the Weatherall Institute of Molecular Medicine at the John Radcliffe Hospital, and the University's Old Road Campus Research Building, a leading institution in cancer research. The chillers were specified by Heaton Design and Engineering , a leading building services consultant based in Witney, Oxon. 

“We proposed a Carrier solution based on the efficiency and proven reliability of the equipment and our excellent working relationship with the company,” said Edward Heaton, managing director, Heaton Design and Engineering. “Carrier’s design and engineering is first-class, and a good match for the university’s challenging sustainability requirements.”

The high-efficiency Carrier chillers were specified in accordance with Oxford University's sustainability strategy of achieving net zero carbon emissions by 2035. This requires energy efficiency improvements and reductions in greenhouse gas emissions from buildings across its estate, while at the same time enhancing occupant comfort and productivity. The Carrier R32 units replaced less efficient chillers that were at end of their working life, delivering a significant improvement in the seasonal energy efficiency ratio (SEER) for the Carrier replacements.

The university estates' sustainability plan also includes adopting long-life, low environmental impact, low maintenance solutions that minimise external impacts and costs over the lifetime of equipment. In support of this goal, the Carrier chillers were treated with super enviroshield condenser coating to protect the aluminium heat exchange surfaces from corrosion and significantly extend their working life. As a result, the condensers are covered by an extended seven-year Carrier warranty. 

The AquaSnap chiller is designed to deliver high-performance and optimal energy consumption in demanding applications. Its combination of outstanding energy efficiency, intelligent controls, connectivity and real-time data access give end users the tools to proactively manage buildings for optimum occupant comfort and efficiency.

"We are very pleased to have been selected by Oxford University to provide vital cooling for three of its world-renowned science and biomedical laboratories," said Didier Genois, vice president and general manager, Carrier Commercial HVAC, Europe. "The chillers support the university's sustainability strategy, while ensuring reliable cooling to maintain the comfort, wellbeing and productivity of people working in the buildings."

The fast-track project, carried out by installer Aircon Services, enabled the laboratories to continue operating without loss of building services support while meeting the tight timetable for completion.

"Carrier provided outstanding support at all stages of the project," said Gavin Hastings, installation lead, Aircon Services. "We have many years of experience supporting the University with air conditioning solutions and maintenance, and are familiar with the buildings and the requirements of the estates department. As a result of the excellent collaboration and fast-track delivery by Carrier, we were able to meet the strict deadlines for completion set by the University."
