C. and a moisture content together imparting to the conditioned air a dew point generally equal to the desired temperature. This conditioned air is simultaneously introduced from above and below at the same rate into the respective faces of the mat to produce in the mat a pair of horizontal and vertically approaching fronts at which moisture condenses out of the conditioned air.
