METHOD AND DEVICE FOR PRODUCING CONDENSATE FROM ATMOSPHERE Russian patent published in 1998 - IPC

FIELD: power engineering; producing water condensate at industrial scale from atmospheric air. SUBSTANCE: atmospheric air is expanded by flow C on turbine 7 of vacuum evaporation plant 6 to pressure below atmospheric value and supplied to first heat-transfer apparatus 9 wherein it cools down atmospheric air flow D which is forced by one of fans 10 driven, for example, by turbine from flow B. Hot air enters vacuum compressor 8 and brought by the latter to atmospheric pressure. In cooling down each flow, air crosses dew point thereby causing water precipitation. Air cooled down to dew point and further cooled below dew point functions in each heat-transfer apparatus as refrigerant for next heat-transfer apparatus. EFFECT: improved economic efficiency. 2 cl, 1 dwg
