INDIRECTLY EVAPORATIVE AIR COOLING PLANT Russian patent published in 2004 - IPC

FIELD: air ventilation and conditioning equipment, particularly for metallurgical workshop crane cabins. SUBSTANCE: device has connected in series heat exchangers having means for fluid organizing. Heat exchangers are composed of plate blocks defining wet and dry channels. Device has inlet pipe for total air flow communicated with dry and wet channel inlet ends and connected with the first heat exchanger; the first outlet pipe for main air flow communicated with dry channel outlet ends and joined to the second heat exchanger, the second outlet pipe for additional air flow communicated with wet channel outlet ends and connected with the first and the second heat exchangers; air supplying fan for total air flow feeding. The second outlet pipe has air-exhauster. Wet channels of the first and the second heat exchangers are closed by caps located on the side of connected heat exchanger ends. The second heat exchanger wet channel inlet ends are connected with dry channel outlet ends. The second heat exchanger is arranged above the first heat exchanger. The second heat exchanger fluid organizing means is located into average in height section of plate block. The first and the second wet channel outlet ends face each other and located coaxially to each other. EFFECT: decreased dimensions without outlet conditioning air quality deterioration. 3 cl, 4 dwg
