A new heat and mass transfer model based on basic principles has been developed for thermal and hydraulic calculations of indirect evaporative cooler performance. Some simplifications have been incorporated to make the model more user-friendly. It is universal and can be used to analyse different evaporative cooler designs and conditions, such as tube- or plate-types and those that use outdoor or room air as the secondary air and either sensible cooling or cooling and dehumidification of the primary air. Variations of the basic calculation procedure for these differing conditions are provided. Compares results from sample calculation for several designs with data from other sources for validation. This model can be used for energy analyses as well as for system or product optimisation.
