Water condenser systems needs cooling towers to reject the heat transferred to the condensed water. Analyzing the diagram PxH shows that lower the temperature of the water in the condensation, generate greater efficiency of the chiller due to the reduction in the lift of compression. But to reduce ECWT, the tower needs a higher electric consumption however, an efficiency gains in the Chiller. From thermal simulations, proven that for psychometric conditions of Brasilia-Brazil, a system operating with high energy demand in the tower, saving electricity, can be superior to 4 times, when compared to the std operation. Evaluating the simulation in other regions, it selects results and guarantees the different local psychometric conditions.
