Abstract:
1. A cooling system comprising: a first-stage cooling assembly that comprises a forced-draft cooling tower having: a final-stage cooling assembly that comprises a forced-draft cooling tower having: the first-stage variable flow water pump pumps cooling fluid from the first-stage cooling fluid reservoir through the first-stage supply piping to, and the cooling fluid from the first stage-cooling tower is in indirect heat exchange relationship with, two or more of the following heat exchangers: warmed fluid is returned directly to wet media of the first-stage cooling tower and then upon being cooled flows down into the first-stage cooling fluid reservoir for reuse, and the final-stage variable flow water pump pumps cooling fluid from the final-stage cooling fluid reservoir through the final-stage supply piping to a heat exchanger serving a final cooling load and warmed fluid is returned directly to wet media of the final-stage cooling tower and then upon being cooled flows down into the final-stage cooling fluid reservoir for reuse and the cooling fluid from the final-stage cooling tower is in indirect heat exchange relationship with the heat exchanger serving the final cooling load, but the first-stage variable flow water pump does not circulate cooling fluid to an air-to-water heat exchanger servicing the ambient air inlet of the first-stage cooling tower.
