Regenerative evaporative cooler, cooling system and core module thereof

Abstract

A regenerative evaporative cooler (REC) including: a plurality of dry channel units allowing indoor air to pass therethrough; a plurality of wet channel units formed to extract a portion of air, which has passed through the dry channel units, and formed to heat-exchange with the dry channel units; an evaporation water supply unit disposed at an upper portion of the wet channel units and supplying the wet channel units with evaporation water; and dry channel shields formed at an upper side of the dry channel units, allowing evaporation water supplied from the evaporation water supply unit to be introduced into the wet channel units, and shielding the upper portions of the dry channel units. The dry channel shield effectively prevents evaporation water sprinkled by the evaporation water supply unit from being introduced into the wet channels and simplifies the configuration of the evaporation water supply unit.

         9 . The cooler of  claim 1 , wherein the evaporation water supply unit is formed in a sprinkler type to sprinkle evaporation water in various directions. 
     
     
         10 . The cooler of  claim 1 , further comprising:
 an extracted air blower for discharging extracted air to the outside.   
     
     
         11 . The cooler of  claim 1 , further comprising:
 an air blower for pressure-transferring indoor air to be cooled to a lower portion of each of the dry channel units.   
     
     
         12 . The cooler of  claim 1 , wherein the dry channel units are formed to allow indoor air to move in an upward direction, and the wet channel units may be formed to allow extracted air to move in a downward direction. 
     
     
         13 . A regenerative evaporative cooler (REC) comprising:
 a dry channel unit allowing sucked indoor air to pass therethrough;   a wet channel unit formed to extract a portion of air which has passed through the dry channel unit, and configured to be wet by evaporation water; and   an air blower disposed at an exit of the dry channel unit and blowing air, which has passed through the dry channel unit, toward an indoor area and the wet channel unit.   
     
     
         14 . A core module of a cooler including stacked unit modules each being comprised of a pair of a dry channel unit and a wet channel unit, wherein the unit module comprising:
 a wet channel fin attached to the interior of the wet channel unit;   a heat transfer plate disposed between the wet channel unit and the dry channel unit;   a dry channel fin attached to an outer surface of the heat transfer plate;   a wet channel guide duct attached to an exit of the wet channel unit to guide extracted air passing through the wet channel unit; and   a dry channel shield formed at an upper side of the dry channel unit, allowing evaporation water supplied from an evaporation water supply unit to flow into the wet channel unit, and shielding an upper portion of the dry channel unit.   
     
     
         15 . The module of  claim 14 , wherein the dry channel shields are disposed at a position spaced apart from an upper end of the dry channel units. 
     
     
         16 . The module of  claim 14 , wherein the dry channel shield is disposed at each dry channel unit, and each dry channel shield is formed in the form of a duct. 
     
     
         17 . A regenerative evaporative cooling system comprising:
 a system for introducing indoor air to the dry channel unit by maintaining the exit of the dry channel unit at a low pressure compared with that of the entrance of the dry channel unit and supplying air, which has passed through the dry channel unit, to an indoor area;   a system or extracting a portion of indoor air which has passed through the dry channel unit to the wet channel unit wet by evaporation water;   a system for cooling the dry channel unit through evaporation of evaporation water; and   a system for supplying evaporation water to the wet channel unit to continuously wet the wet channel unit.
