Abstract: The invention concerns a thermic machine comprising a reactor of the adsorption-desorption type, a condenser and an evaporator. According to the invention, the machine is constituted by a first vertical hermetic cylindrical tank section (1), traversed by a first hydraulic circuit (4) and containing the reactor, an envelope arranged at the periphery of the first tank section (1), which is connected to a second hydraulic circuit (6) and which together with the wall of the said first tank section (1) constitutes the condenser (5), and a second hermetic tank section (2) in communication with and arranged below tank section (1), the second tank section being traversed by a third hydraulic circuit (7) and constituting the evaporator.

Abstract: The invention pertains to refrigeration units which operate by means of heat energy, and especially solar energy, wherein the mode of operation consists of a desorption phase and an adsorption phase. The energy collector (8) contains a material (10) with high adsorption and desorption capacity, such as zeolite, and it is connected to an evaporator (2) situated within an insulation chamber.
