Abstract

Cycle régénérateur fermé, dont la température minimale du fluide de travail est à son tour proche de la température critique, mais supérieure à celle-ci, et proche de la température ambiante utilisée pour réfrigérer un foyer froid; on sélectionne la valeur de l'isobare supérieur pour qu'il coïncide avec l'isobare dit suprême, qui présente la valeur maximale moyenne de chaleur spécifique à pression constante, dans la zone péri-critique, au-dessus de l'isotherme critique, et délimitée en pression entre un cinquième et cinq fois la pression critique, en fixant l'isobare inférieur pour fournir le maximum d'un facteur dans lequel le numérateur est le travail spécifique, et le dénominateur la somme des valeurs absolues de la variation d'enthalpie spécifique de chaque étape du cycle.
