Abstract
PURPOSE:To make it possible to measure the water balance for a cooling tower without using a flow meter and with a simple constitution by measuring the wet bulb temperature of the outside air of a cooling tower and the inlet temperature and outlet temperature of the cooling water and calculating the amount of evaporation and amount of cooling water circulation. CONSTITUTION:Temperatures are measured by respective thermometers T1-T3 and the amount of evaporation is calculated from those measured temperatures in a calculation controller 7. In the calculation controller 7 a curve of the performance of a cooling tower is stored on which the cooling capacity (log U/N) of the cooling tower which is a function of the ratio N of the water and air of the cooling tower which is a function of the ratio N of the water and air of the cooling tower is taken along the axis of ordinates and along the axis of abscissas the logarithm of the ratio of the amount of cooling water circulation L and amount of gas G (logL/G). At the intersection of this curve and the evaporation curve based. on the amount of evaporation value U/N is determined, and, further, from the value U/N the amount of cooling water circulation L is calculated. The amount of evaporation and the amount of cooling water circulation which are calculated are inputted through the modems 8 and 9 to a host computer 10 on the side of the base station, and the cooling water 1 is monitored. Further, in the calculation controller 7 the thickening ratio is calculated from the amount of the evaporation and a valve V is opened so as to supply the replenishing water to bring the thickening ratio to a specified thickening ratio.
