Abstract:
A combination heating and cooling apparatus which comprises:a compartment into which an item to be heated or cooled may be placed;an electromagnetic wave generator;wherein during a first mode of operation of the apparatus, electromagnetic waves generated by the electromagnetic wave generator are directed into the compartment to heat the item;at least one sorber having a housing defining an enclosure;a sorbate/sorbent compound located within the enclosure;wherein during a second mode of operation of the apparatus, electromagnetic waves generated by the electromagnetic wave generator are directed to the sorber;wherein electromagnetic waves transmitted by the electromagnetic wave generator are propagated through the enclosure to desorb the sorbate from the sorbate/sorbent compound;an evaporator connected to both the condenser and the sorber and positioned in heat exchange relation with the compartment; anda controllable valve interposed between the condenser and the evaporator;wherein sorbate which is desorbed in the sorber is condensed in the condenser and then, during a second mode of operation of the apparatus, controllably released into the evaporator to create a cooling effect and cool the item after which the sorbate is drawn back into the sorber.
