Abstract

A refrigerator and/or freezer incorporates one or more reactors containing a complex compound of a metal salt and a polar gas adsorbed thereon in which the volumetric expansion of the complex compound is restricted during adsorption, and which reactors comprise one or reaction chambers having a maximum means mass diffusion path length of less than about 15 mm, and/or a maximum thermal diffusion path length of less than 1.5 mm.
