Abstract
PURPOSE:To control the cooling water flow rate by a method wherein the rotational frequency of a cooling water pump or the opening degree of a cooling water system is controlled in accordance with cooling water temperature. CONSTITUTION:Temperature at cooling water inlet is sensed with a cooling water thermometer 9 or temperature of the condensate from a condenser 4 is sensed with a condensate thermometer 8 or temperature of cooling water is sensed with a vacuum gage 7 equipped at the condenser 4. The cooling water flow rate is controlled with said detection signal by controlling the rotational frequency of a motor 12, which is the driving source of the cooling water pump 10, or by controlling the opening degree of a valve 11, which is provided in the cooling water supply route of the condenser 4. For example, the temperature 15 induced from the vacuum gage 7 is inputted in a comparator 13 to calculate the compared result with the set value set in advance in the comparator 13 and the controlling operation of the valve 11 in the cooling water supply route of the condenser 4 or of the motor 12 of the pump 10 is performed, resulting in preventing the condenser 4 from being overcooled.
