With training an important facet of expanding the CO2 transcritical market, on 25 March Carrier Commercial Refrigeration opened its CO2OLacademy field training facility in Germany, at its Research Development Center in Mainz. One of only a few training facilities with a live-store environment, the CO2OLacademy facility will improve the skills and technical knowledge of Carrier Commercial Refrigeration field technicians in Europe.
Carrefour has big plans for CO2. The company won’t go so far as to declare an all-CO2 philosophy, yet its expansion into warmer ambient climates, in particular two transcritical pilot stores in Valencia, would suggest that notion is closer to reality than they might think. R744.com sat down with the Director International Support at Carrefour, Jean-Michel Fleury, about the expanding CO2 transcritical market in Europe.
The biannual IIR Conference in Ohrid, Macedonia typically focuses on the use of ammonia in refrigeration but this year’s event, held April 16-18, involved formal discussions on CO2 for the first time, in response to its increasing use. This included presentations on the specific equipment required for the use of CO2 in different refrigeration applications.
SONAE MC’s Amad Hafez spoke to R744.com about their experience with cascade systems in Portugal and the retailer’s feelings about their future use of natural refrigerants. While the company praised the high savings their CO2 subcritical commercial refrigeration systems were able to provide, they are still seeking an alternative to R134a. The performance of its two CO2/NH3 stores has not met expectations. However, SONAE MC is keeping an eye on CO2
With CO2 transcritical retail stores in warmer European climates expected to hit 100 in the next two to five years thanks to technology developments like adiabatic cooling, ejectors and parallel compression, Bulgaria represents a potential growth market for the technology. Although there are still barriers to overcome in the EU Member State positive developments are on the way with leading retailer Kaufland seriously considering CO2-only systems.
Carrier began working with tegut…., a German food retailer, in 2010 with a contract to supply a number of CO2OLtec transcritical CO2 refrigeration systems to the chain. R744.com had the opportunity to talk with Carrier Commercial Refrigeration’s Director Turnkey Operations, Christoph Brouwers about the companies’ experience with transcritical CO2.
Moving south to Spain, R744.com interviews the professors Nacho Fandos (IES Llombai) and Ramón Cabello (Jaume I University of Castellón), pioneers of CO2 training in the country. Thanks to collaboration with secondary schools, the Jaume I University of Castellón and companies such as Frost-Trol, training courses have been successfully run since 2011.
Enex has been actively developing solutions to increase CO2 system efficiency in warm ambient climates like Spain and Italy. Using parallel compression and ejectors in unison, the company has realised significant efficiency gains and cost (first cost + energy cost) reductions. With more than 60 units installed with auxiliary compressors and more than 20 units using ejectors, the company’s accumulated data proves the energy savings of Enjector® technology can be as
As the worldwide market for CO2 (R744) technologies continues to develop, gaining ground in new application areas within Europe and picking-up momentum in food retail in North America, R744.com is pleased to announce its Partnership with more and more leading CO2 heating and cooling technology providers, including compact Kältetechnik GmbH. R744.com provides an online platform for suppliers, end-users, consultants, academics and policy makers to connect and learn about
Revised criteria for the “Blauer Engel” (Blue Angel) label will require data centres with cooling demands higher than 50 kW to use natural refrigerant-based cooling systems or systems that do not require refrigerant.
