INDIRECT EVAPORATIVE AIR COOLING DEVICE Russian patent published in 2000 - IPC

FIELD: air- conditioning systems. SUBSTANCE: device has housing with tray, branch pipes for supply of common air flow and discharge of main and auxiliary air flows, supply and suction, plate stacks having alternating surfaces forming passages made from moisture-proof material for common air flow and passages made from capillary porous material for auxiliary flow; at one end they are communicated with passages of main flow and at other end they are blanked off. To enhanced efficiency of cooling, space between capillary porous plates is separated by pair of corrugated watertight plates forming double triangular "wet" passages on either side of evaporating plate and "dry" passages of square section. EFFECT: enhanced efficiency of cooling; reduced power requirements. 2 dwg
