Abstract
An energy-saving, direct-contact parallel-flow heat exchanger includes a vertically oriented tower open at the top and bottom for defining a gas-flow conduit. A spray-head adjacent to the top of the tower sprays droplets of relatively warm brine into the air which flows downwardly in response to drag forces being exerted by the falling droplets and is compressed as a heat-exchange process takes place between the air and the droplets. The cooled droplets that fall to the bottom of the tower are collected and separated from the air. An air turbine associated with the tower produces energy in response to the downward flow of air in the tower.
