Abstract:

PROBLEM TO BE SOLVED: To preclude the generation of freezing of an air intake unit contacted with outdoor air or a louver plate and the freezing between filler members in the side of the louver plate in the coldest period.
SOLUTION: Freezing, generated between the filler members when a circulating cooling water temperature in an outdoor air intake unit 11 is raised to an equal value as that in a mixing chamber 13 side or the temperature is reversed to a value higher than that in the mixing chamber 13, is thawed gradually by a method wherein the rotation of a fan 21 for a cooling tower 10 is reversed from a normal rotation into a reverse direction for a predetermined period of time based on a command from an operation control unit 23 and a motor 22 for the fan 21 is controlled through inverter control while the opening degree of a valve 24 is regulated and the amount of spray water per unit area from the outdoor air intake unit 11 side is increased above that from the mixing chamber 13 side.
