Abstract

L'invention concerne un récipient de sorption (1) comprenant une enveloppe flexible (10), laquelle délimite un volume intérieur (11) dans lequel est introduit au moins un fluide de travail (7) et un premier fluide de sorption (3) qui, lors d'un apport de chaleur, libère le fluide de travail (7) sous forme gazeuse et, lors d'une dissipation de chaleur, lie le fluide de travail. Le volume intérieur (11) est subdivisé en au moins un premier volume partiel (111) et au moins un deuxième volume partiel (112) et au moins un troisième volume partiel (113). Le premier volume partiel (111) contient le premier fluide de sorption (3) et le deuxième volume partiel (112) contient soit au moins un condenseur ou un évaporateur, soit au moins un deuxième fluide de sorption. L'invention concerne en outre un accumulateur à sorption ou une pompe à chaleur ou un transformateur de chaleur comprenant au moins un tel récipient de sorption.
