Natural refrigerants MAC systems could reduce GHG emissions by 30% in China

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.

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

FMI retailer experiences: more pilot CO2 trancritical installations to come in the US

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.

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
