Over 100 manufacturers, retailers, contractors and consultants gathered in the Italian city of Padova last week to hear how new developments in ejector technology are improving the performance of CO2 refrigeration systems in warm climates.
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
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.
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.
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
