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
