This study, conducted by Alexandre M.S. Costa of the State University of Maringá and published by the State University of Ponta Grossa in Brazil, analyzes the annual energy performance of a closed-loop hot water solar thermal system under various weather conditions in 6 Brazilian cities (Curitiba, São Paulo, Rio de Janeiro, Recife, Salvador and Brasília) using the -f chart method. This method is based on 2 different approaches. It calculates the fraction (f) of monthly heat load that comes from solar energy.
This presentation was given by Stéphane Joblot of E-Sol, a company specialized in renewable energy studies, during a workshop organized in the framework of the Energievie.info programme of the Alsace region, with the support of ADEME, the French Environment Agency. After giving a general overview of various solar thermal techonololgies and applications, the speaker shares the findings from a case study which analyzed the process needs of an agri-food company in the city of Colmar. This company operates 5 days a week and needs 4.000 liters of water at 60° C daily.
