Abstract

La présente invention concerne un dispositif à cycle de réfrigération, qui comprend : une unité de stockage de chaleur qui est disposée entre de multiples unités côté source de chaleur et unités côté charge et qui met en œuvre un échange de chaleur avec un fluide frigorigène qui s'écoule entre les multiples unités côté source de chaleur et unités côté charge ; un dispositif de commutation de stockage de chaleur qui commute entre un trajet d'écoulement qui introduit le fluide frigorigène depuis les multiples unités côté source de chaleur jusqu'à l'unité de stockage de chaleur et un trajet d'écoulement qui introduit le fluide frigorigène depuis les unités côté charge jusqu'à l'unité de stockage de chaleur ; une unité de sélection d'unité côté source de chaleur qui, lorsque le dispositif de commutation de stockage de chaleur commute vers le trajet d'écoulement destiné à introduire le fluide frigorigène depuis les unités côté charge jusqu'à l'unité de stockage de chaleur, sélectionne une unité côté source de chaleur dans laquelle est introduit le fluide frigorigène qui s'écoule depuis l'unité de stockage de chaleur ; et un dispositif de régulation qui met en œuvre une régulation de façon à fermer une première vanne tout ou rien et à ouvrir une seconde vanne tout ou rien dans l'unité côté source de chaleur sélectionnée par l'unité de sélection côté source de chaleur.
