Method for cooling a product, particularly, for liquefying a gas, and device for implementing this method

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...

Beschreibung
Zusammenfassung:	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. The method also includes the following steps: effecting N-1 heat exchanges each time the refrigerant enters the evaporator ( 103, 203 ) of a cycle and each time the refrigerant enters the condenser ( 201, 301 ) of the following cycle for condensing the refrigerant in the condenser.
