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, the electromagnetic waves 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; a waveguide for coupling electromagnetic waves generated by the electromagnetic wave generator 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; a condenser connected to the sorber; an evaporator connected to both the condenser and the sorber and positioned in heat exchange relation with the compartment; and a 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.
