A combination heating and cooling apparatus which comprises a compartment (276) into which an item to be heated or cooled may be placed; an electromagnetic wave generator (16, 278), wherein during a first mode of operation of the apparatus, the electromagnetic waves are directed into the compartment (276) to heat the item; at least one sorber (12) having a housing (66) defining an enclosure; a sorbate/sorbent compound located within the enclosure; a waveguide (14, 288) for coupling electromagnetic waves generated by the electromagnetic wave generator (16, 278) to the sorber (12), wherein electromagnetic waves transmitted by the electromagnetic wave generator (16, 278) are propagated through the enclosure to desorb the sorbate from the sorbate/sorbent compound; a condenser (38) connected to the sorber (12); an evaporator (42) connected to both the condenser (38) and the sorber (12) and positioned in heat exchange relation with the compartment (276); and a controllable valve (48) interposed between the condenser (38) and the evaporator (42); wherein sorbate which is desorbed in the sorber (12) is condensed in the condenser (38) and then, during a second mode of operation of the apparatus, controllably released into the evaporator (42) to create a cooling effect and cool the item, after which the sorbate is drawn back into the sorber (12). |
