A method for determining the composition of any circulating water in cooling systems was developed basing of the proposed actual evaporation rate. The evaporation rate is a flow of evaporated water divided by a flow of loss drops at the cooling unit. The formulas for the determination of this rate in stationary conditions are given. The proposed mathematical model is confirmed by calculation comparing to the existing one, which does not allow predicting concentration factor of circulating water. The opportunity to implement stable system of automatic control using this model is given. An admissible concentration factor for CaSO4 and the method for determination of rational concentration factor for system are presented.

Keywords: evaporation rate, cooling system, mathematical model, concentration factor, flow control, acid dosing.
