御装置。 The cooling water from the cold water pit at the bottom of the cooling tower is sent to the plant's heat exchanger, and the return water from the heat exchanger is made to flow down from the nozzle at the top of the cooling tower to the cold water pit, and the flowing water is introduced by a suction fan. In a cooling tower having a structure in which the cooling water is brought into contact with air, the cooling water temperature controller controls and calculates the deviation between the measured cooling water temperature value and the cooling water temperature set value and transmits the flowing water temperature set value as its operation output; A cooling tower temperature control device comprising a flowing water temperature controller that controls the rotation speed of the suction fan based on an operational output obtained by controlling and calculating the deviation between the measured value of the flowing water temperature and the set value of the flowing water temperature.
