Thermal performance of an evaporatively cooled building: parametric studies.

Describes the modelling of a single-storey office building in a hot and dry climate for evaporative cooling. The counterflow cooling tower is modified to precool the tower inlet air by the tower exit air in a heat exchanger. The study indicates that centralised evaporative air cooling is feasible to maintain near-perfect comfort conditions in hot and dry climates. Modified cooling tower and roof evaporative cooling further enhance the scope of evaporative cooling for comfort applications.
