Carrier Commercial Refrigeration Europe marked its 1,000th CO2OLtec installation at a Kiwi store (Kiwi Laskentunet) in Norway. The project represents a landmark achievement for Carrier in the deployment of natural refrigerant technologies around Europe. The transcritical refrigeration system uses carbon dioxide (CO2, R744) to improve operating efficiency of the refrigeration system, while reducing its environmental impact.

Carrier is one of the world’s leading producers of high-technology heating, air-conditioning and refrigeration solutions. The company estimates that collectively the 1,000-plus CO2OLtec installations represent in CO2 emissions the equivalent of removing 70,000 cars from the road for the duration of the systems’ operation.

First installed in 2004, the CO2OLtec range of products uses transcritical booster technology to deliver cooling for low and medium temperature applications. The technology currently provides more than 100 megawatts of medium temperature capacity to more than 1,000 sites in 19 European countries.

In mild to cold climates, field data indicates that the CO2OLtec refrigeration system improves energy efficiency by an average of 10% compared to traditional HFC systems.

Efficient operation in warm climates

Germany has the highest number of CO2OLtec systems in operation, followed by Norway and Switzerland. To bring viable CO2 technology to all of Europe, Carrier has worked to develop specialised solutions, such as ejectors, economizers and mechanical sub-coolers, which allow the CO2OLtec system to operate efficiently in warmer climates.

Carrier has made tremendous progress toward tearing down the former 'CO2 equator', thanks to new technological developments. A number of projects have been delivered in Spain and Italy, including a successful field trial of innovative controllable ejector technology," said Christoph Brouwers, Director, Mechanical Systems Programs, Carrier Commercial Refrigeration, Europe.

Supported by a wide range of applications

The rapid uptake of Carrier CO2OLtec systems over the past 10 years can also be attributed to the wide range of applications supported by the CO2OLtec product family, which includes small CO2 condensing units to large indoor and outdoor refrigeration racks. This product diversity means the CO2OLtec system can provide solutions for applications ranging from small stores to hypermarkets and distribution centers.

CO2OLtec integrated systems

The CO2OLtec product family recently was expanded to include integrated systems designed to take control of a building's thermal energy supply. These range from basic heat recovery for space heating or hot water systems, to fully integrated systems providing refrigeration, heating and cooling, ventilation and lighting control from a single source.

CO2OLtec integrated systems can deliver up to 35% energy savings versus an equivalent R404A system with a gas boiler, while reducing greenhouse gas emissions by up to 58%. According to Carrier, the combination of operational benefits of the system and the new EU F-Gas Regulation, will contribute to the products’ ongoing success.

We see more and more customers turning to natural refrigerant solutions for their refrigeration needs. At Carrier, the number of CO2OLtec projects in operation has more than doubled over the past two years," said Gunter von Starck, director, marketing, Carrier Commercial Refrigeration, Europe.
