Sealed, thermally insulated tank has tank walls fixed to the load-bearing structure () of a floating structure, the tank walls having, in succession, in the direction of the thickness from the inside to the outside of the tank, a primary sealing barrier (), a primary insulating barrier (), a secondary sealing barrier () and a secondary insulating barrier (), at least one of the insulating barriers includes juxtaposed non-conducting elements, each non-conducting element including a thermal insulation liner () and load-bearing elements that rise through the thickness of the thermal insulation liner in order to take up the compression forces, characterized in that the load-bearing elements of a non-conducting element include pillars () of small transverse section as compared to the dimensions of the non-conducting element in a plane parallel to the tank wall.

A sealed, thermally insulated tank consists of tank walls fixed to the load-bearing structure of a ship, the tank walls having, in succession, in the direction of the thickness from the inside to the outside of the tank, a primary sealing barrier, a primary insulating barrier, a secondary sealing barrier and a secondary insulating barrier, at least one of the insulating barriers consisting essentially of juxtaposed non-conducting elements (), each non-conducting element including a thermal insulation liner, at least one panel and load-bearing partitions rising through the thickness of the thermal insulation liner in order to take up the compression forces. These partitions include at least one anti-buckle partition () that includes a plurality of anti-buckle wall elements that have a respective orientation forming an angle relative to a general longitudinal direction of the anti-buckle partition, for example forming corrugations or double-wall portions.

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.
