WET DRY INTEGRATED CIRCULATION COOLING SYSTEM

An integrated circulating water cooling system includes at least one load (20); an air cooling sub-system (30); a wet surface cooling sub-system (50); at least one temperature sensor (92); a control (70); and a coolant circulation sub-system for fluidly circulating coolant from the at least one load (20) to the air cooling sub-system (30) to the wet surface cooling sub-system (50) and back to the at least one load (20). The control (70) selectively operates the wet surface cooling sub-system (50) and the air cooling sub-system (30) based on at least one of temperature sensed in the water circulation sub-system (80); or sensed ambient temperature.
