Outdoors and indoors air streams are induced to travel in opposite directions through the adjacent passages of a plate-fin heat exchanger. A water stream is simultaneously induced to circulate through the passages occupied by the cooler of the air streams. Heat is transferred across adjacent passages, causing vaporization of a portion of the water stream into its accompanying air stream, thus keeping the cooler stream saturated with water vapor. The hotter air stream is cooled and dehumified while the cooler one increases in temperature and humidity content. Very close temperature approaches can thus be achieved at the heat exchanger, with the resultant economies in the energy requirements for ventilation.
