The paper submits the description and the temperature performances of an autonomous adsorption refrigerator. The volume of the chamber is equal to 7 litres. As the refrigerant was used the distilled water. It is shown, that such device can support the lowered temperature in the chamber without use of source of energy during 12 hours.
To obtain the lower temperature in the evaporator, the thermal and sorption characteristics of the sorbent bed with active carbon - acetone pair were studied. The possibility of thermal control over refrigerating capacity and of the provision of uniform heat output from the evaporator is illustrated.
