15th IIR-Gustav Lorentzen Conference on Working Fluids

15th IIR-Gustav Lorentzen Conference on Working Fluids

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…

CO2 can now compete with HFCs even in warm climates, shows SINTEF research

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.

Gustav Lorentzen 2014: what will be the next big thing for CO2?

A wealth of new research and technological developments on CO2 as a refrigerant in centralised commercial refrigeration, heat pumps, glass door merchandisers and data centre cooling was presented at the 11th biennial Gustav Lorentzen conference on natural refrigerants. The event provided valuable insight into current and upcoming technology trends for all alternative refrigerants. Whilst CO2 stole the show, R744 research continues to focus on improving
