A method for cooling a product (P) including N ordered adsorption/desorption cycles (), each cycle having the following steps: expanding a refrigerant in liquid phase from a condenser () inside an evaporator () for evaporating at least one portion of the refrigerant, and; adsorbing this refrigerant in vapor phase inside at least one adsorption/desorption chamber () 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. The method also includes the following steps: effecting N-1 heat exchanges each time the refrigerant enters the evaporator () of a cycle and each time the refrigerant enters the condenser () of the following cycle for condensing the refrigerant in the condenser.
