R744 technology innovator Systemes LMP has created a CO2 system for artificial cooling of ice slabs called the “CRYSTAL”, already installed at an ice arena in Canada. The CRYSTAL is a multi-compressor unit with an operating capacity of 30 to 140t ideal for new constructions of ice rinks under renovation. Thanks to its state-of-the-art design, the unit features total heat recovery of the compressors, which can be used for commercial space heating, hot water, mechanical room.
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.
At the Seafood Expo Global in Brussels from April 20-22, German manufacturer Ziegra showcased its industrial and commercial ice machines using CO2 and hydrocarbons respectively, but questioned the 150-gram charge limit leaving a gap in their product range. Working with Skaginn, Icelandic manufacturer FROST, who traditionally use ammonia in their refrigeration systems for fish processing, are also looking into CO2 as a viable industrial solution.
A motivation to transform industry perception of CO2 as a refrigerant was behind Hillphoenix’s decision to supply the first transcritical CO2 ice rink installation in the U.S.
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
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.
As climate change continues to permeate political and social dialogue, an increasing number of food retailers are working to green their corporate image and take the lead in engaging in more sustainable practices. Refrigeration consumes a considerable amount of energy and contributes substantially to greenhouse gas emissions. At ATMOsphere Europe 2015, supermarket giants Carrefour, Delhaize and SONAE MC discussed their use of lean, green, GHG-cutting refrigeration machines.
During the 2000 Olympic Games in Sydney, Australia, Greenpeace challenged Coca-Cola to stop using hydrofluorocarbon (HFC) gas as a refrigerant in its millions of vending machines and beverage coolers worldwide. The campaign worked, probably well beyond Greenpeace’s wildest dreams. Coca-Cola’s Tomas Ambrosetti and Steven Cousins explain how the Company’s number of HFC-free units installed worldwide has grown to 1.4 million in the feature interview of the 4th edition of Acceler
Hurtigruten’s cruise liners allow tourists to discover the landscapes of Norway, as well as experience natural phenomena such as the northern lights and the midnight sun. However, like all transport and tourist activities, Hurtigruten’s operations have a direct influence on the environment. The company’s environmental policy therefore has an important role to play, and as part of their sustainability practices, Hurtigruten’s terminal in Bergen uses the natural refrigerant
