摘要：
A method for controlling the temperature of water to be fed into a water cooling tower in which when the driving power required to drive motors to be controlled is in excess of the power which can be derived from a frequency converter, some of the motors are driven by a constant-frequency power supply while the remaining motors are driven by the frequency converter. Therefore, the temperature of water to be fed into the water cooling tower can be continuously controlled without increasing the capacity of the frequency converter.
