Breakthrough Carrier AquaForce® Chillers With PUREtec™ Refrigerant to Power Switzerland District Heating Project

Two Carrier AquaForce® water-cooled screw chillers with the new PUREtec™ refrigerant have been selected for the innovative Plan-les-Ouates district heating project in Geneva, Switzerland. The AquaForce chillers with PUREtec refrigerant feature the next-generation, low Global Warming Potential (GWP) refrigerant HFO-1234ze(E), providing 2.5 megawatts of total heating capacity for optimal performance in an environmentally sustainable package. Carrier, the world's leader in high-technology heating, air-conditioning and refrigeration solutions, is a part of UTC Building & Industrial Systems, a unit of United Technologies Corp. (NYSE:UTX).

The first phase of the mixed-use real estate development project in Plan-les-Ouates enables the energy efficient recovery and re-use of waste heat from a data center onsite, providing heating to local offices and other facilities. As part of the second phase, the extended installation is expected to provide heating to 3,000 individual homes within a planned residential zone. This project represents Europe's first district heating project based on a water-cooled screw chiller using the new PUREtec refrigerant compliant with new European Union fluoronated gases regulation.

Carrier France manufactured and tested the breakthrough technology in its Montluel factory, located near Lyon, France. The system was delivered by Walter Meier Company, Carrier's distributor in Switzerland. The installation of the system was completed in June and the commissioning is scheduled for July.

"Having demonstrated world-class quality, testing capabilities and a compelling proof-of-concept, Carrier is proud to present and install this revolutionary solution in Europe, alongside its distributor partner," said Didier Genois, engineering and marketing HVAC Europe director, UTC Building & Industrial Systems. "We're proud to deliver Europe's first installation of a water-cooled screw chiller with the new PUREtec very low global warming refrigerant." 

With a GWP value of just 7, PUREtec reduces the direct global warming potential of traditional refrigerants for this application by 99.5 percent.

"As a pioneer of sustainable solutions, Carrier is committed to deploying technologies that minimize environmental impact while serving customer needs," said John Mandyck, chief sustainability officer, UTC Building & Industrial Systems. "With the introduction of the AquaForce line of indoor and outdoor chillers with PUREtec refrigerant, Carrier is once again taking the lead in the development of environmentally responsible solutions."
