91B125/PG/ALF A refrigerator 1 includes a cylinder 2 containing a bed of adsorbent material 3 and a gas, e.g. carbon dioxide. A piston compresses the gas which is adsorbed by the adsorbent material 3 and the heat of adsorption is dissipated by fins 4 to atmosphere. The piston, when retracted, decompresses the gas which desorbs from the adsorbent material 3. Repeated compression and decompression of the gas causes a cold zone to be created within the material 3 which is thermally linked to a location to be refrigerated.
