Abstract:
An evaporative cooler for a turbine air intake system, the evaporative cooler comprising:a reservoir for holding water; a media; a manifold for dispersing the water from the reservoir above the media; a manifold flow line extending from the reservoir to the manifold; a collector for collecting the water below the media; a pump for pumping the water through the manifold flow line from the reservoir to the manifold; a return line for returning the water from the collector to the reservoir; at least one water supply line for supplying the water to the reservoir; a valve structure for controlling flow through the at least one water supply line; a level sensor for indicating whether a top surface of the water within the reservoir is: 1) above or below a first water level; and 2) above or below a second water level positioned below the first water level; and an electronic controller that interfaces with the valve structure and the level sensor, wherein the controller causes the valve structure to: 1) start water flow to the reservoir at a first flow rate when the top surface of the water falls below the first water level; and 2) increase water flow to the reservoir from the first flow rate to a higher second flow rate when the top surface of the water falls below the second water level.
