Abstract

L'invention porte sur un procédé pour appliquer un travail vers l'extérieur à l'aide d'une énergie thermique environnementale. Une énergie thermique et une énergie froide produites par une pompe à chaleur sont absorbées par des milieux constituant une source de chaleur et une source froide ; ensuite, la source de chaleur et la source froide coopèrent avec le milieu à la température environnementale pour actionner un appareil d'application de travail thermique afin d'appliquer un travail vers l'extérieur ; l'appareil d'application de travail thermique applique un travail aussi bien quand la température s'élève que quand la température chute ; un échange de travail à étages multiples est utilisé dans toutes les étapes de la totalité du processus, ou, autrement dit, de multiples milieux sont utilisés pour effectuer un échange de chaleur de nombreuses fois afin d'effectuer un refroidissement ou un chauffage graduels jusqu'à une température requise pour une certaine étape, et, cependant, des milieux froids et thermiques de différentes qualités sont obtenus et stockés séparément ; de multiples processus d'échange de chaleur de la même séquence permettent aux qualités des milieux d'être graduellement améliorées, et, par conséquent, des milieux froids et chauds de haute qualité qui peuvent être utilisés sont obtenus, et l'énergie froide et l'énergie chaude sont totalement utilisées. L'invention porte également sur un système pour appliquer un travail vers l'extérieur à l'aide d'une énergie thermique environnementale.
