Cooling apparatus and cooling system utilizing adsorbents

In a cooling apparatus, air within a room is first introduced into a radiator-type adsorber 1, where moisture contained in the air is adsorbed by A-type silica gel. The resulting low-humidity air is subsequently introduced into a desorption cooler 5, where moisture is desorbed from B-type silica gel, thereby humidifying and cooling the air. The resulting low-temperature air is then used for cooling. When a cooling capacity of the cooling apparatus is lowered, air from a heat source is introduced into the radiator-type adsorber 1, where the moisture is desorbed from the A-type silica gel, thereby recovering the adsorbability thereof. The high-humidity air resulting from the desorption of the moisture is subsequently introduced into the desorption cooler 5, where the moisture contained in the air is adsorbed by the B-type silica gel, thereby recovering the desorption cooling capacity thereof.
