Abstract

L'invention est destinée à l'alimentation de chaleur destinée aux locaux d'habitation, publics ou industriels, ainsi qu'aux équipements technologiques industriels. Pour réduire les pertes de chaleur dans le milieu environnant et, par conséquent, la consommation d'énergie, le système d'alimentation de chaleur est muni d'une installation de refroidissement dont le condenseur est inclus hyrauliquement dans la conduite d'amenée du caloporteur et dont l'évaporateur est inclus dans la conduite d'évacuation du caloporteur. Dans un autre mode de réalisation, le système est également équipé d'un échangeur de chaleur, relié hyrauliquement à la conduite d'amenée, et d'un branchement de celui-ci, via un dispositif réducteur. L'installation de refroidissement dans les deux modes de réalisation comprend plusieurs condenseurs ayant des degrés différents de la température de condensation et reliés en série en suivant la voie du caloporteur; elle comprend plusieurs évaporateurs ayant des degrés différents de la température d'ébullition du caloporteur, reliés en série en suivant la voie du caloporteur. L'utilisation de l'invention permet de réduire d'un facteur multiple les pertes de chaleur via les conduites de caloporteur ainsi que de réduire d'un facteur de 1,64 à 1,84 l'énergie consommée à cette fin.
