Migros Ticino has opened a new supermarket in Switzerland that uses Biaggini’s new TotalEnergy integrated CO2 system to serve refrigeration and HVAC needs.
De Rigo CO2 system cuts energy usage by 28% compared to standard system thanks to addition of ejectors, parallel compression and inverter technology.
INTARCON, a Spanish manufacturer of commercial and industrial refrigeration units, is piloting a double cascade R290-CO2-CO2 refrigeration system in an installation in Cordoba, southern Spain “It’s a double cascade refrigeration system configured to use two CO2 loops in conjunction with a propane loop to provide cooling to cabinets, freezers and cold rooms in a supermarket,” Daniel Campaña…
Workshop participants at ATMOsphere Ibérica in Madrid agreed that training is key to triggering wider uptake of natural refrigerants in the Iberian Peninsula.
More than 50% of the members of a Spanish trade group are working with natural refrigerants.
New technologies including ejectors are improving the efficiency of CO2 transcritical systems in warmer climates, heard last week’s Gustav Lorentzen conference.
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…
