CO2 evaporators should be operated without superheat, heat recovery should be employed, says Professor Armin Hafner.
Amman, Jordan, store is saving 40,000kWh per year in a high-temperature climate after leap-frogging from R22 to CO2, bypassing HFCs.
The EU-funded MultiPACK project is testing the performance of cooling/heating CO2 solutions in supermarkets and other buildings.
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…
Armin Hafner, a professor in refrigeration technology at the Norwegian University of Science and Technology (NTNU), gave one of the most inspiring presentations at ATMOsphere Asia 2016, highlighting some of the latest technological advances in ejectors, transport, and industrial refrigeration solutions as well as superseded technology that helped shape the natural refrigerant market we know today.
