Abstract
A system for optimizing the control of the water temperature within a cooling tower is disclosed. The temperature and the relative humidity of the air outside the cooling tower are measured and are selectively utilized as inputs to a plurality of modules containing function blocks in a logic arrangement. The function blocks produce an output signal indicative of the wet bulb temperature of the outside air which is compared to the cooling tower water temperature causing the speed of the cooling tower fans to be adjusted in response to the temperature difference therebetween.
