A dew-point air cooler comprises a heat exchanger including a) a bank of vertical tubes 3 arranged to pass primary air 1 to be cooled along the outside of the tubes with exchange of heat; b) means for passing pre-cooled secondary air 2 through the interior of the tubes; c) means 4,5,7,13 for introducing water periodically into the tubes from the top and forming a film of water on the inner wall of the tubes; d) means for discharging the humidified secondary air; and e) means for passing at least a portion of the cooled primary air to a space to be cooled. <IMAGE> |
