NOCTURNALLY OPERABLE WATER HARVESTER AND ASSOCIATED METHOD

摘要

In use, the method of operating the apparatus (1) to condense water from ambient air entails circulating the heat exchange fluid (3) between the radiator (2) and the (condenser 4), whilst simultaneously: emitting radiation from the emission surface (8) of the radiator (2) to the nocturnal atmosphere so as to cool the heat exchange fluid (3); receiving the heat exchange fluid (3) into the condenser (4) so as to cool the fins (23) to, or below, the dew point of the ambient air such that water condenses from the ambient air onto fins (23); and flowing cool dehymidified air discharged from the condenser (4) onto the emission surface (8) of the radiator (2). The presence of cool, dehumidified air flowing over the face of the emission surface (8) of the radiator (2) prevents or reduces contact between warm moist ambient air and the emission surface (8); thus preventing or reducing the formation of dew on the emission surface (8).
