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
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!
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
