The first combined CO2 heat pump installed at a Scandinavian hotel delivers significant energy savings of up to 69%, heard the audience at a recent conference in Ohrid.
Opened today, the store uses parallel compression and ejector technology to cope with high ambient temperatures common in the Middle East.
From 17-18 September, at the Crystal Palace Hotel in Tianjin, China, the International Symposium on Natural Working Fluid CO2 Refrigeration and Heat Pump Technology will be held to discuss how to enhance the market competitiveness of CO2 in China.
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.
The continually diminishing CO2 efficiency equator was a hot topic at ATMOsphere Europe 2015. Several system manufacturers presented the methods by which CO2 transcritical system efficiency can be improved, with ejector technology taking the spotlight. According the several presenters the end of the so-called “CO2 equator” is in sight. + VIDEO
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
The use of CO2 as a refrigerant is becoming increasingly widespread in food processing industries, and is beginning to make inroads in industrial heat pump applications. TINE Dairy, which is Norway’s largest producer, distributor and exporter of dairy products, is committed to upholding its sustainable profile and strives to keep up to date with the most climate friendly and energy efficient technologies. With this in mind, TINE’s factory close to the city of Trondheim in
