  From the description of FIG. 1 and FIG. 2 in the above-mentioned Patent Document 1, the arrangement mode of the adsorbent in the above-mentioned Patent Document 1 is in contact with the outer surface of a member such as a tube or a fin constituting the heat exchanger, and It can be understood that they are arranged to fill the gap. From the viewpoint of disposing more adsorbent, it is preferable to dispose the gap between the tubes and fins in this way.

  However, considering only the process of heating the adsorbent with the heat of the heat exchanger to desorb the refrigerant from the adsorbent, it is preferable to dispose the adsorbent only in the region in direct contact with the tubes and fins. This is because the adsorbent is generally formed of a zeolite or ceramic material and has a low thermal conductivity. More specifically, since it is necessary to transfer heat to the adsorbent that is not in direct contact with the tubes and fins, the heat transfer between the adsorbents is necessary to transfer heat to the adsorbent away from the tubes and fins. This is because it takes time.

  The present invention has been made in view of such problems, and the object thereof is to quickly desorb the refrigerant from the adsorbent while securing the adsorption capacity of the refrigerant by arranging more adsorbent. An object of the present invention is to provide an adsorber for a refrigerator.

The heat conducting member is composed of at least one sheet-like component, and the adsorbent is in contact with at least one of a pair of surfaces of the sheet-like component. The sheet-like component is wound and arranged so that one surface is along the other surface, thereby forming an arrangement space in which the adsorbent is arranged, and the adsorbent is arranged in the arrangement space. As a result, the sheet-like component is in contact with one surface and the other surface.

  According to the present invention, the heat conducting member having a higher thermal conductivity than the adsorbent is provided so that one end thereof is in contact with the outer surface of the heat exchanger. You can communicate efficiently toward the edge. Since the heat conduction member is arranged so that the other end faces in the direction in which the adsorbent extends while in contact with the adsorbent, it efficiently transfers heat to the adsorbent that is not in direct contact with the heat exchanger. And the desorption of the refrigerant from the adsorbent can be performed quickly.

The adsorbent 124 is regenerated in the vessel 10A.

  In this second state, the first heat exchanger 11B of the refrigerator adsorber 10B functions as an evaporator that evaporates liquid phase refrigerant to generate refrigeration capacity, and the second heat exchanger of the refrigerator adsorber 10B. 12A functions as a cooler for cooling the adsorbent 124. The first heat exchanger 11A of the refrigerator adsorber 10A functions as a condenser for cooling the water vapor desorbed from the adsorbent 124, and the second heat exchanger 12A of the refrigerator adsorber 10A heats the adsorbent 124. Functions as a heater.
