A new transcritical CO2 refrigeration system has been installed in a fishing vessel in Norway, which combines four DSI V3/26/100 freezers and one DSI V3/12/100, all using CO2 as the refrigerant. The new system allows DSI freezers to increase their capacity by 20-30%. Other vessels are in-line for the tests results of this first installation to replace their current R22 systems.
Heatcraft Worldwide Refrigeration has launched the Kirby CO2 evaporator suitable for low temperature freezer applications and direct expansion systems. The evaporator fares well in terms of heat exchange efficiency, capacity, reliability and compressor displacement.
In July 2014, leading CO2 technology player SANDEN expanded its operations in Europe, opening a new branch called SANDEN Environmental Solutions, in France (Rennes, Brittany). The Rennes office is tasked with expanding the market for CO2 solutions in Europe, the Middle East and Africa, a move that signals SANDEN’s commitment to developing the market for CO2 solutions, including residential, professional and commercial applications.
According to a new report by Carrier Commercial Refrigeration almost two-thirds of large supermarkets from North and West European countries now use natural refrigerants in their stores, a trend driven by company-wide sustainability policies, and one that is outpacing EU legislation. The study, developed in partnership with market development company shecco, seeks to provide a clear picture of the key drivers for and against the adoption of sustainable refrigeration and refrigerant options.
At the 11th Gustav Lorentzen Conference on Natural Refrigerants, Johanna Gloël of GIZ Proklima presented on the potential for China to reduce greenhouse gas (GHG) emissions through the use of natural refrigerants, which would replace fluorinated gases in car air conditioning systems. The research suggests that GHG emissions in China could be reduced by 30% by 2030.
Adding to the growing knowledge base on ejectors in CO2 transcritical refrigeration systems, research presented by SINTEF at the Gustav Lorentzen 2014 conference (GL 2014) shows that a CO2 ejector refrigeration system with parallel compression can achieve around 25% energy savings compared to a standard R404A system in warm climates. SINTEF also analysed an integrated energy system with CO2 refrigeration installed in Norway, demonstrating a 30% reduction in energy
“Refrigeration systems need to be adapted to each country to guarantee maximum efficiency,” says Tewis
Alfonso Olcina from Spanish company Tewis gave R744.com an exclusive interview, and insights into the potential use of natural refrigerants for commercial applications in warm countries such as Spain. Olcina also discussed the company’s current and future projects for Southern and Eastern Europe, and Central and Latin America.
The FMI Energy & Store Development Conference in St. Louis gave retailers the opportunity to discuss their experiences with installed CO2 systems. Harrison Horning from Delhaize America / Hannaford, Jamie J. Meyers from Walgreens, and Rob Olden from GI Energy, discussed pilot transcritical CO2 stores in Maine and Illinois, whilst Benny Smith from Price Chopper talked about the first CO2 system in North America, installed in 2008.
Italian-based Castel is a leading global manufacturer of components for refrigeration and air conditioning systems, serving more than 75 countries. Recently announcing its Silver Partnership with R744.com, Castel will soon showcase a new series of Ball Valves, for installation in commercial and industrial refrigeration systems, as well as heat pumps, on R744.com. See preview below.
Attended by over 600 people, the FMI Energy & Store Development Conference focuses on energy-efficiency and conservation in the food retail industry, as well as the latest innovations in store design and merchandising. Kicking off the event as in previous years was the EPA’s GreenChill Awards ceremony, a program that recognises individual stores for investments…
