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
