Multi Purpose Multistage Evaporative Cold Water and Cold Air Generating and Supply System

A system comprising:

• an initial-stage (IS) cooling assembly that comprises an IS cooling tower having:
• an ambient air inlet without an associated heat exchanger,
• an air outlet,
• a cooling fluid reservoir disposed near a bottom of the IS cooling tower;
• and
• a fan dedicated to the IS cooling tower, and configured to move air through the IS cooling tower;
• a final-stage (FS) cooling assembly that comprises a cooling tower having:
• an air inlet,
• an air outlet,
• a cooling fluid reservoir disposed near a bottom of the FS cooling tower,
• a fan dedicated to the FS cooling tower, and configured to move air first through the FS air-inlet heat exchanger then the FS cooling tower,
• a heat exchanger at the air inlet of the FS cooling tower;
• and
• a variable-flow pump that is adapted to pump cooling fluid through FS supply piping;
• wherein
• the IS cooling fluid reservoir at least connects to a pre-cooling coil of a primary cooling load and one or more of the following heat exchangers:
• the FS air-inlet heat exchanger;
• and
• an optional mid-stage (MS) air-inlet heat exchanger;
• wherein warmed cooling fluid returns directly to wet media of the IS cooling tower and to the IS cooling fluid reservoir for reuse,
• wherein
• the FS cooling fluid reservoir connects to a primary cooling load and optionally one or more additional cooling loads and warmed cooling fluid returns directly to wet media of the FS cooling tower and returns to the FS cooling fluid reservoir for reuse.
