Abstract Traditional air conditioning systems make up for a large percentage of the modern world’s power consumption and it is therefore imperative that alternatives to traditional systems are implemented. This report analyses the performance of the indirect and regenerative evaporative cooler and how different parameters of the model can affect the performance of the system. The relative humidity of the inlet air, the inlet air velocity, the channel gap, the channel length and the product to working air velocity ratio of the cooler were investigated and analysed with respect to the qualities of the product air using the CFD software ANSYS Fluent. The results show that the channel gap had the most substantial effect on the product air temperature, wet bulb effectiveness and Coefficient of Performance (COP) of the evaporative coolers, with a maximum COP of 9.95 being achieved. However, for a maximised cooling performance, each parameter must be considered with respect to the real-world applications of the device. The result of the thesis demonstrates the applicability of evaporative cooling for use in hot and arid climates, which is shown through an analysis of suitability of application in the Middle East.
