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
FRIENDSHIP is pleased to announce that our newest paper about electroplating of selective cobalt-chromium coating is now published online in the journal of Solar Energy Materials and Solar Cells. The paper, Environmentally sustainable electroplating of selective cobalt-chromium coating on stainless steel for efficient solar collectors,… Read More »Publication on electroplating of selective cobalt-chromium coating!
In the past months, CEA worked on the prototype of TES (Thermal Energy Storage) to integrate into FRIENDSHIP solution. So far CEA selected and characterized the Phase Change Material (PCM) and finalized the design of the prototype. Several heat exchanger designs were considered, using parallel… Read More »Ongoing manufacturing of the Thermal Energy Storage
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
On 24th and 25th of November, FRIENDSHIP team got together for the M30 progress meeting. Six months after the first in-person meeting in Sweden, the consortium met again in Munich (Germany), hosted by Clariant, one of the project’s industrial partners. At the beginning of the… Read More »FRIENDSHIP Progress Meeting in Munich
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!
EuroSun is one of the main events on solar energy for buildings and industry in Europe. This year the conference took place in Kassel (Germany), from 26th to 29th September, and its organization was a joint effort of the International Solar Energy Society (ISES) and… Read More »FRIENDSHIP at EuroSun 2022
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
For the third time, FRIENDSHIP was presented at the Renewable Heating and Cooling workshop during the Sustainable Places Conference 2022, held both online and in Nice (France), on 7th September. The Project Coordinator followed up on the presentation delivered last year and in 2020 at… Read More »FRIENDSHIP at Sustainable Places 2022
The Horizon 2020 project FRIENDSHIP reached the halfway milestone this month and for the occasion the whole consortium met in Sweden for a two-day event. The meeting started with the projection of the film: “Our Planet: Our Business” by David Attenborough, to remind about the… Read More »Halfway through the project
