The conference, taking place in Trondheim, Norway, on June 13–15, will include sessions on CO2, ammonia, hydrocarbons, water and air.
The biennal Gustav Lorentzen Conference on Natural Refrigerants is once again brought back to Trondheim, the hometown of Professor Gustav Lorentzen and the cradle for the revival of CO2 as refrigerant. The conference has become a globally important meeting place for more than 350 field experts from industry and research. The conference typically has 120 oral…
Test shows that enhanced R744 technology can compete with traditional single-temperature R404A container up to 50°C.
CO2-based technology can provide efficient heating and cooling in Spanish supermarkets despite the country’s warm climate, according to a paper presented by experts from the NTNU and SINTEF at Gustav Lorentzen this week. Estimations based on six representative cities show how HFC-free solutions lead to remarkable energy savings. The EU F-Gas Regulation bans the use…
12th IIR Gustav Lorentzen Natural Working Fluids Conference, to take place in Edinburgh next week, will review latest trends and innovations related to natural refrigerants.
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
DTI at Gustav Lorentzen 2014: can ice storage and Vortex Flow Sensors improve CO2 system efficiency?
The Danish Technological Institute (DTI) presented two papers on topics related to CO2 refrigeration systems at the 2014 Gustav Lorentzen Conference on Natural Refrigerants held in China from 31 August – 2 September. In the first presentation, ice storage for a transcritical refrigeration system is suggested in order to achieve greater energy savings in warmer climates, and flexible power consumption.
