An apparatus capable of providing rapid cooling and/or freezing comprises a cabinet or container having a cooling chamber, one or more reactors each containing a complex compound formed by adsorbing a polar gas on a metal salt, in which the polar gas is alternately adsorbed and desorbed on the complex compound, and in which the complex compound is formed by restricting the volumetric expansion and controlling the density during adsorption of the polar gas on the metal salt, whereby the complex compound is capable of adsorbing said polar gas at a rate of greater than 15 moles per mole hour of the complex compound in about 20 minutes or less, a condenser for condensing the polar gas, an evaporator thermally exposed to the cooling chamber for providing cooling therein, and conduits and one or more valves for directing said polar gas from the one or more reactors to the condenser, from the condenser to the evaporator and from the evaporator to the one or more reactors.

An apparatus capable of providing rapid cooling and/or freezing comprising: (a) a cabinet or container having a cooling chamber therein; (b) one or more reactors each containing a complex compound formed by adsorbing a polar gas on a metal salt, and in which said polar gas is alternately adsorbed and desorbed on said complex compound, said metal salt comprising a halide, nitrate, nitrite, oxalate, perchlorate, sulfate or sulfite of an alkali metal, alkaline earth metal, transition metal, zinc, cadmium, tin or aluminum, or sodium borofluoride or a double metal chloride, or mixtures thereof, and wherein said complex compound in said one or more reactors is formed by restricting the volumetric expansion and controlling the density thereof during said adsorption of said polar gas on said metal salt, whereby said complex compound is capable of increased reaction rates in the number of moles of said polar gas adsorbed and/or desorbed per mole of said complex compound per hour at adsorption or desorption times of less than 60 minutes, respectively, as compared to a complex compound formed without restricting the volumetric expansion and controlling the density thereof, and wherein said complex compound in a desorbed condition is capable of adsorbing said polar gas at a rate sufficient to achieve rapid cooling or freezing in about 30 minutes or less; (c) condenser means for condensing said polar gas and evaporator means thermally exposed to said cooling chamber for providing cooling therein, and conduits and one or more valves cooperating therewith for directing said polar gas from said one or more reactors to said condenser means, and from said evaporator means to said one or more reactors; and (d) heating means cooperating with said one or more reactors for heating said complex compound therein.
