Abstract

The paper discusses physico-chemical processes occurring during the interaction of water environment and air in cooling tower. As the results of exergy analysis of those processes, it was found that ratio of energy and exergy flows is associated with mass transfer and heat transfer. The effectiveness of exergy transformation in the cooling tower was evaluated. The mechanism for determining the exergy losses in the local processes of mass transfer, heat transfer and dissipative effects occurring in the cooling tower is proposed.
