ABSTRACT:
A counterflow cooling tower includes a casing having cooling air inlet openings formed at its lower end and cooling air outlet openings formed at its upper end, a contact body positioned in the casing and formed from a plurality of contact layers arranged in banks and defining a plurality of water and air flow channels therebetween providing communication between the air inlet and outlet openings, a water distribution installation positioned above the contact body for supplying warm water to be cooled to the channels, channel caps on top of only some of the channels fitted geometrically to adjacent contact layers and covering some of the channels against water from the water distribution installation, and an air supply installation for supplying cooling air from the air inlet openings through substantially all of the channels to the air outlet openings, whereby the temperature and moisture-content of air supplied to the channels to which warm water is supplied are increased while the temperature of air supplied to the other channels is increased by heat transfer through adjacent layers of the contact body without substantially changing the moisture-content thereof. The water distribution installation may include elongated spray nozzles installed in the areas between the channel caps and running at an angle to the channels over the extent of the banks.
