The Heat and Mass Transfer Technology Center (CTTC) at the Universitat Politècnica de Catalunya – BarcelonaTech (UPC) participated in the Economic COgeneration by Efficiently COncentrated SUNlight (ECOSUN) project to develop a low-cost, concentrated thermal and photovoltaic cogeneration system that increases the system’s electrical efficiency. This was achieved by reducing the absorption temperature of solar radiation and utilising the residual heat obtained from cooling the photovoltaic modules, to meet the thermal needs for heating or cooling through an absorption machine.
The CTTC of the UPC worked on the thermal and fluid dynamic optimisation of the thermal-photovoltaic concentration receiver by numerically simulating the entire device under different geometries and working conditions. This technology is designed for domestic and industrial applications. Potential application cases were studied under various environmental conditions for different regions and countries of use. A first prototype was validated under real operating conditions. The numerical results indicate an increase in the overall heat transfer coefficient of between 25% and 30%.
Consortium, budget and funding
The project also involved the Institute of Electrical Measurement and Sensor Systems of the University of Graz (Austria) and the Solar Energy Research Center of Ankara University. ECOSUN started in February 2020 and ended in January 2023. It had a total budget of €1,281,639 from the European ERA-LEARN programme.
