A general mathematical model of evaporative cooling devices.

Modèle mathématique général des dispositifs de refroidissement à évaporation.

Type of article: Article

Summary

The paper presents a general nondimensional mathematical model for the description of all types of evaporative cooling devices in today's use (water cooling towers, evaporative condensers and evaporative fluid coolers, air washers, dehumidifying coils, etc.). The system of differential equations describing nonadiabatic evaporation processes is transformed to a pure nondimensional form by the introduction of nondimensional coordinates and parameters and by the substitution of a straight air saturation line instead of the real one. This nondimensional model forms a basis for simple and rather accurate methods for rating various types of evaporative cooling devices.
