An apparatus capable of rapidly cooling or freezing a com- position comprising a walled housing member (10) having a cool- ing chamber (20) and a door for accessing the cooling chamber from the exterior of the housing, an evaporator (40) and a blower (42) for circulating cold air from the evaporator to the cooling chamber, first (22) and second (24) reactors each containing a complex compound consisting of a metal salt and ammonia ad- sorbed thereon, heaters (21, 23) in the reactors for heating the complex compound, and valves (28, 29, 31, 32) and conduits for directing ammonia from the evaporator to the reactors, from the reactors to the condenser (30), and from the condenser to the eva- porator, and control means (45) for sequentially operating the heaters for alternately heating the complex compounds in the reactors, operating the air handling means and one or more of the valves, and switching means for turning the apparatus on and off. The apparatus may be of a size suitable for a household appli- ance, and includes an embodiment combining the components with a microwave oven for selectively providing rapid cooling and microwave heating.
