Type of article: Article

Summary

The paper deals with the development of a mathematical model for the performance prediction of air-cooled condensers formed by three distinct zones: desuperheater, condenser and subcooler. Each piece of straight tube, between two return bends, is treated as a separate heat exchanger. The energy balances over each zone, for both air and refrigerant streams, together with the effectiveness equations, form a set of non-linear equations, which are solved numerically. In the paper six coil configurations are studied. Predicted results are compared with existing experimental data, with generally good agreement. A few possible applications of the method are also presented.
