After investigating numerically, the different GAX (Generator-Absorber heat eXchange) cycles for absorption cooling at -20°C and -40°C from solar heat, a prototype was designed for typical FRIENDSHIP operating temperatures. This prototype was designed to meet at cold demand at -20°C using solely environmentally friendly refrigerants… Read More »Prototype of the absorption chiller under testing
Solar heat for industrial processes
In the last months, SINTEF developed a lubrication free turbo-compressor for the steam heat pump of the FRIENDSHIP system. The designed compressor prototype allows temperature lifts of up to 30 Kelvin in a single stage compression and was dimensioned to a capacity range of around… Read More »Compressor Prototype For The Heat Pump Is Installed!
A prototype of TES (Thermal Energy Storage) is being designed for later tests at CEA, on two experimental facilities, with different Heat Transfer Fluids (HTF) -pressurized water and thermal oil- and operating ranges. Several heat exchangers designs have been considered, using parallel or concentric tubes,… Read More »Progress on the thermal storage
SINTEF and CEA are investigating different innovative solutions for absorption cooling at -20°C and -40°C from 100-250°C solar heat, in particular a GAX (Generator-Absorber heat eXchange) cycle based on commercial components, like Plate Heat Exchangers (PHE). This innovative design improves the heat and mass transfers,… Read More »Innovations on the ejector and absorption chillers
FRIENDSHIP project is glad to announce the publication of a scientific article on absorber coatings, written by our partner Kemijski inštitut – National Institute of Chemistry. The paper is related to the research work on the development of the spectrally selective absorber coatings and refers… Read More »Publication on absorber coatings!
