Abstract

L'invention porte sur un élément chauffant à volume constant. On observe une demande pour l'amélioration du coefficient de performance pour un cycle de réfrigération qui est un cycle de Carnot inverse, et on observe une demande pour une amélioration du rendement thermique d'un moteur thermique. Pour améliorer le rendement thermique d'un moteur thermique, la température de vapeur humide d'une turbine à vapeur est portée à une température élevée. On observe une demande pour un accroissement du rendement, la suppression du bruit et la réduction de la perte mécanique dans un compresseur adiabatique. On observe une demande pour la réduction de la quantité d'énergie consommée dans une chaudière, pour l'amélioration du rendement électrique d'une turbine à vapeur et aussi pour l'amélioration de la consommation de combustible dans des dispositifs tels que les automobiles. Le coefficient de performance du cycle de réfrigération est amélioré en remplaçant le processus de compression adiabatique d'un cycle de réfrigération, c'est-à-dire d'un cycle de Carnot inverse, par un processus de chauffage à volume constant. L'élément chauffant à volume constant utilise la variation thermique d'un volume fixe dans la loi de Boyle-Charles de la thermodynamique. Un dispositif d'utilisation de chaleur possédant un rendement d'énergie de conversion global théorique de 1 est obtenu en combinant un cycle de pompe à chaleur qui utilise un élément chauffant à volume constant et un moteur thermique à cycle de Carnot. Un dispositif d'utilisation de chaleur possédant un rendement d'énergie de conversion global de 1 ou plus est obtenu par l'utilisation appropriée d'une source de chaleur à basse température du cycle de réfrigération et d'une source de chaleur à basse température du moteur thermique.
