Abstract
A cooling tower controlling system includes a plurality of cooling towers, a plurality of pumps, a circulation line through which circulating cooling water flows, a temperature measuring unit, a first load controlling unit, and a second load controlling unit. The temperature measuring unit measures a temperature TEof the circulating cooling water at a position upstream of a heat exchange unit and downstream of a storage unit. The first load controlling unit controls a rotational speed of the cooling fans so that an absolute value ΔTE of the difference between the temperature TEand an outside air wet-bulb temperature TEcomes within a first approach temperature APcorresponding to a first load in a first load period. The second load controlling unit controls a rotational speed of the cooling fans so that the absolute value ΔTE of the difference between the temperature TEand the outside air wet-bulb temperature TEcomes within a second approach temperature APcorresponding to a second load in a second load period.
