ERENS, P. J.. A Procedure for the Design or Rating of Counterflow Evaporative Cooler Cores. R&D j. (Matieland, Online) [online]. 1987, vol.3, pp.18-25. ISSN 2309-8988.

A computerised method for determining the size of evaporative cooler cores based on the method of Mizushina is described. An additional program using the above procedure can be used to rate the performance capabilities of a given coil with specified inlet conditions. Block diagrams for both procedures are given and problems encountered in using the method are discussed. Some example calculations are also given. Although the principles of the method have previously been described in the literature the author has attempted to point out some of the problems and pitfalls experienced in developing a successful algorithm for the design or rating of evaporative coolers.
