Abstract

PURPOSE: To maintain excellent heat exchange ratio by operating valves, which is set on a bypa equipped with a refining unit, by a water quality detecting unit for a circuit through which cooling water circulates.
CONSTITUTION: When the electric conductivity increases to a prescribed value, e.g., 500μv/cm or higher, valves 8a, 8b are opened by an electric eonductivity measring unit 6, so that a constant quantity of cooling water is passed through a refining apparatus 9 consisting of a zeolite tank 9a, an anion and a cation exchange resin tanks 9b, 9c set on the bypath 7, and is refined. When the electric conductivity of the cooling water decreases to a prescribed value, e.g., 300μv/cm or lower, the valves 8a, 8b are closed by the unit 6. The cooling water is cooled in a cooling tower 1, circulated by a pump 2 through a heat exchanger 3. Water 5 is replenished to a water tank installed at the base of the tower 1 in order to maintain the water level constant
