For example, the temperature of the cooling water is about 30 ° C. in summer as described above. In this case, 70 ° C. or higher is required, and heating means such as a boiler is used to obtain such temperature.

The refrigeration cycle in the case of using cooling water at ℃ is shown together with the adsorbent water content (p). In the figure, the adsorption process is from point A to point B to point C, and from point C to point D is point A.

ましい。As described above, in the conventional adsorption type refrigerator system, in order to obtain the refrigerating output, a considerably high temperature driven heat source is required. Conventionally, in order to obtain such a high temperature heat source. In addition, a heating means such as a boiler was used, but from the viewpoint of energy saving in recent years and the so-called exergetic way of thinking that also considers the environment, such a high temperature heat source is generated by heating with a boiler or the like. Instead, it is desirable to use the heat emitted from the production process of a factory or a thermal power plant as it is.

Especially, the cooling water is 30 ° C. as described above. At this time, as is clear from FIG. 4, the desorption start point D ′ is not located on the regeneration process line in the figure, and the water content of the adsorbent does not change at all, resulting in no adsorption / desorption action. ..
