To restrain inefficient operation.SOLUTION: A cooling tower system 100 includes a fan 18 which allows cooling water before cooling to be brought into contact with the outside air, a motor 20 which drives the fan 18, an inverter 36 which supplies electric power to the motor 20, a temperature detection section (thermometer 32) for detecting a cooling water temperature after cooling, and a wet-bulb temperature control section 52 which supplies electric power from the inverter 36 to the motor 20 in such a manner that the cooling water temperature is at a set cooling water temperature which is a target temperature. The wet-bulb temperature control section 52 changes the set cooling water temperature so that the electric power supplied from the inverter 36 to the motor 20 does not exceed the prescribed electric power.SELECTED DRAWING: Figure 9 【課題】非効率な運転を抑制する。【解決手段】冷却塔システム１００は、冷却前の冷却水に外気を接触させるファン１８と、ファン１８を駆動するモータ２０と、モータ２０に電力を供給するインバータ３６と、冷却後の冷却水温度を検出する温度検出部（温度計３２）と、冷却水温度が、目標温度である設定冷却水温度となるように、インバータ３６からモータ２０に電力を供給させる湿球温度制御部５２と、を備え、湿球温度制御部５２は、インバータ３６からモータ２０に供給する電力が所定電力を超えないように設定冷却水温度を変化させる。【選択図】図９
