ABSTRACT:
A dual-adsorber cooling system for an automobile has a pair of adsorbers, a cooling vessel, a pair of absorbate outgoing passages extending from the cooling vessel to each of the adsorbers individually, a common adsorbate return passage, a condenser, and a condensation passage. A bypass passage enables the two adsorbers to directly communicate each other to exchange heat. The adsorbers are opposingly disposed with an intervening plenum therebetween. The engine exhaust gas is introduced to the central plenum, and the external air is guided to the central plenum through the adsorbing adsorber so that a blend of the exhaust gas and the air is directed to the desorbing adsorber in the plenum, whereby the adsorbing adsorber is cooled and the desorbing adsorber is heated up. The amount of the external air taken can be controlled according to the amount of the exhaust gas. A process switchover controller can adjust the process cycle period according to the temperature of the exhaust gas. An air flow amount controller can control the amount of the external air taken according to the amount of available heat. The adsorbers may be heated by microwave energy.
