On 7 April, on the eve of China Refrigeration 2015, one of the largest trade shows in the HVAC&R industry shecco organised the first ever ATMOsphere Network Shanghai. Supported by Danfoss and Mitsubishi Heavy Industries (MHI), the event gathered over 60 experts from industry, research institutions and government, who gathered to discuss the latest natural refrigerant trends in the world’s largest HVAC&R market. The event also featured a preview of the upcoming bilingual English-Chi
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
Carbon dioxide, which is making progress as a refrigerant in the North American supermarket sector, is also increasingly infiltrating its way into the industrial sector in cascade and secondary systems, which was evident at the IIAR (International Institute of Ammonia Refrigeration) 2015 Conference & Exhibition, which took place in San Diego from 22-25 March.
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.
Heatcraft’s Bohn CO2 unit cooler line, designed for supermarkets or those involved in commercial refrigeration, helps to minimise environmental impact while maintaining- and improving- efficiency levels. With a broad range of unit coolers to choose from, there will be no one left wanting.
The continually diminishing CO2 efficiency equator was a hot topic at ATMOsphere Europe 2015. Several system manufacturers presented the methods by which CO2 transcritical system efficiency can be improved, with ejector technology taking the spotlight. According the several presenters the end of the so-called “CO2 equator” is in sight. + VIDEO
2014 was an important year of ‘firsts’ for CO2 in terms of the refrigerant being applied in a wider range of applications in Europe, including transport, ice rinks, the HORECA food service sector, and more. The sixth annual ATMOsphere Europe 2015 conference heard from the technology providers and contractors of these projects, including Carrier Transicold, Green & Cool, Green Cooling, Thermo King and AF Consulting.
