A new flagship market in downtown Boston will keep its seafood fresh with a Howe flake ice machine using CO2 as a natural refrigerant.
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.
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.
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.
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.
