Abstract

　L'invention concerne un système de collecte de chaleur solaire à haute efficacité dans lequel la solidification de sel fondu est rendue plus facile à traiter en réduisant l'ampleur selon laquelle le sel fondu est utilisé. De la chaleur est échangée entre du sel fondu avant d'être chauffé par un collecteur de chaleur de sel fondu 1 et de l'huile de synthèse chauffée par un collecteur de chaleur d'huile 21, de telle manière que le sel fondu est préchauffé dans un préchauffeur de sel fondu 22. Étant donné que le sel fondu préchauffé est chauffé par le collecteur de chaleur de sel fondu 1, c'est-à-dire que l'huile chauffée par la chaleur solaire est utilisée pour chauffer le sel fondu, l'énergie thermique recueillie par le collecteur de chaleur de sel fondu 1 peut être réduite. Ceci facilite le traitement de la solidification de sel fondu, et rend inutile le fait de devoir fournir de l'huile chauffée par un réchauffeur d'huile à un générateur de vapeur d'eau (partie chauffée), ce qui élimine la nécessité de disposer d'un réservoir destiné à stocker la chaleur de l'huile de synthèse, et permet de réduire proportionnellement les coûts globaux d'installation et de réduire la déperdition thermique pendant le temps d'immobilisation et les périodes non ensoleillées telles que pendant la nuit.
