Procédé solaire de production de froid basse température (-28°C) par sorption solide-gaz

Abstract : The aim of this work is the design and experimentation of a thermochemical process for cold production purpose at -28°C using low grade heat (70°C) supplied by flat plate solar collectors. An exergetic analysis of the thermochemical dipole and of ideal thermodynamic cycles led to the definition of an original solar process. This process involves two cascaded cycles functioning in parallel. The cycle is discontinuous and presents a day phase of heating and regeneration and a night phase of cold production. A dynamic simulation allowed the study of its functioning depending on the weather conditions and on the dimensions of the process. A prototype covering the needs of a cold chamber loosing 40 W of cold continuously was built and tested in real conditions in Perpignan. It demonstrated the feasibility of this innovative concept and validated the hypothesis used to develop the model. A study of the process functioning was lead by simulation in different meteorological conditions and for different heat sources (solar, geothermal or industrial waste). It showed the potentialities of the concept.
