An apparatus capable of providing rapid cooling and/or freezing comprises a cabinet or container having a cooling chamber (26), one or more reactors (14, 32, 42) 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 i n 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 (16) for condensing the polar gas, an evaporator (20) thermally exposed to the cooling chamber for providing cooling therein, and conduits (17, 18, 22, 29) and one or more valves (13, 23, 25, 27) directing said polar gas from the one or more reactors (14) to the condenser (16), from the condenser (16) to the evaporator (20) and from the evaporator (20) to the one or more reactors. |
