It can be obtained by firing at ℃. The quicklime thus obtained is porous and highly reactive because it releases CO 2 while maintaining the volume of the raw limestone. Calcined quicklime is produced by heat treating CaCO 3 or Ca(OH) 2 under reduced pressure or in the presence of a carrier gas such as N 2 gas at a temperature of about 300 to 800 °C, preferably about 300 to 500 °C. It can also be manufactured. For example, CaO, which has a large specific surface area and is called an active powder described in Arai et al., Gypsum & Lime No. 178 (1982) p. 31-40, can also be used as soft burnt lime. The soft calcined quicklime can be used as a powder or can be granulated or molded and filled into the adsorption chamber 2. Furthermore, the adsorption chamber 2 may be filled with soft calcined quicklime wrapped in cloth, wire mesh, or the like that is permeable to water vapor.

When the upper space of the refrigerant storage chamber 8 becomes atmospheric pressure, the diaphragm 12 is pushed by the atmospheric pressure and moves downward, causing the rod 11 to break the thin film member 10. From the torn thin film member 10, the coolant 14 flows through the hollow pipe 17, reaches the coolant absorption sheet 7, and is absorbed by the absorption sheet 7. Adsorption chamber 2 and evaporation chamber 3
is pre-depressurized, e.g. 0.1~30torr, preferably 0.5
~20torr. Since the adsorption chamber 2 and the evaporation chamber 3 have been reduced in pressure in advance, water vapor evaporates from the refrigerant from the refrigerant absorption sheet 7 in the evaporation chamber 3 provided adjacent to the object storage chamber 4 . During evaporation, the water contained in the refrigerant absorbs the sensible heat of cooling the object to be cooled, thereby cooling the object 6 in the object storage chamber 4 to be cooled. The generated water vapor is adsorbed by the soft calcined lime 5 in the adsorption chamber 2, and the adsorption chamber 2 and the evaporation chamber 3 are always maintained at a reduced pressure.
