Their efficiency comes from increased suction vapor density, which is a significant advantage in colder climates, says NTNU researcher
New study found ejector system outperformed a conventional booster system across all ambient conditions
The EU funded MultiPACK project tested Integrated CO2 heat pump systems in two Italian hotels and found COP values up to 6, depending on the ambient temperatures
Professor Armin Hafner sees this and other innovations expanding the market for CO2 HVAC&R systems.
Professor Armin Hafner of NTNU calls for governmental loans to overcome higher costs of NatRef systems.
The EU-funded MultiPACK project is testing the performance of cooling/heating CO2 solutions in supermarkets and other buildings.
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.
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…
