Abstract: A method for cooling a product (P) including N ordered adsorption/desorption cycles (100, 200, 300), each cycle having the following steps: expanding a refrigerant in liquid phase from a condenser (101, 201, 301) inside an evaporator (103, 203, 303) for evaporating at least one portion of the refrigerant, and; adsorbing this refrigerant in vapor phase inside at least one adsorption/desorption chamber (120, 220, 320) containing a zeolite adsorbent (Z) whereby cooling a remaining portion of the refrigerant in the evaporator to a predetermined low temperature, the low temperature decreasing from one cycle to the next.
