Abstract
A cooling tower having an evaporative media along with a liquid distribution system that distributes hot liquid over the evaporative media. The cooling tower includes a pair of heat exchanger modules that each have a first set of passageways in fluid communication with a first flow duct and a second set of passageways in fluid communication with a second flow duct. The heat exchanger module transfers heat from a first air stream into a second air stream. The cooling tower further includes a first bypass flow path that extends between the first heat exchanger module and the second heat exchanger module whereby a bypass door regulates airflow there through.
Claims19
A cooling tower having a vertical axis, comprising:
- an evaporative media located at a first position along the vertical axis;
- a liquid distribution system that distributes hot liquid over said evaporative media;
- a first heat exchanger module having a first set of passageways in fluid communication with a first flow duct and a second set of passageways in fluid communication with a second flow duct;
- a second heat exchanger module having a third set of passageways in fluid communication with a third flow duct and a fourth set of passageways in fluid communication with a fourth flow duct;
- a lifting device that moves said second heat exchange module to a second position and a third position;
- and
- an air current generator that directs air through said first, second, third, fourth passageways and bypass flow path through the cooling tower.
