The article considers the problem of effective protection of the cooling tower shell using the screen with a ventilated air gap. The aim is to determine the optimal parameters of the air gap. In operation, the calculations were performed showing the effects of temperature conditions and the thickness of the gap on the aerodynamic and thermal modes of operation. The article made conclusions based on the done calculations. The optimum thickness of the gap, provided heating air inlet, which provides the ability to assimilate air moisture throughout the layer and delete it in the atmosphere, which in the future will eliminate condensation on the cold surface of a concrete shell.
