Abstract

L'invention porte sur un dispositif de climatisation, lequel dispositif comporte une fonction de stockage de la chaleur, et peut être facilement installé dans une maison ou un établissement de petite taille typique, tel qu'un kiosque de vente. Ce dispositif de climatisation, qui comporte un cycle de réfrigération (50) avec lequel un réfrigérant est amené à circuler par la liaison d'un compresseur (2), d'un échangeur de chaleur extérieur (4), d'un décompresseur (5) et d'un échangeur de chaleur intérieur (17), comporte de plus un dispositif de stockage de chaleur (12), qui a un corps de stockage de chaleur (13) rempli par un agent de stockage de chaleur et qui est apte à échanger de la chaleur entre l'agent de stockage de chaleur de ce corps de stockage de chaleur (13) et le réfrigérant circulant dans une tuyauterie de réfrigérant. La tuyauterie de réfrigérant du dispositif de stockage de chaleur (12) est reliée au cycle de réfrigération (50), de telle sorte que de la chaleur peut être stockée dans l'agent de stockage de chaleur par l'utilisation d'une énergie électrique nocturne.
