The invention refers to a multipurpose system of recipients that is made up of two coaxial cylindrical vessels (1) and (2), which delimit a vaporization space (i1) and a condensation space (i2) that are connected by a pipe (3) and a laminating valve (R1), and is equipped with some valves (S1) and (S2). The refrigeration agent is introduced in and discharged from the system by means of the valves (R2) and (R3), the lid (4) being mounted air-tightly onto the cylindrical vessel (1).
