FRIENDSHIP is glad to present our newest paper about one-dimensional mathematical modeling of two-phase ejectors, which is now published online in the journal Applied Thermal Engineering. The paper, One-dimensional mathematical modeling of two-phase ejectors: Extension to mixtures and mapping of the local exergy destruction, was… Read More »Publication on one-dimensional ejector model for mixtures
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
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
