Abstract: The dependency of the existing designs of evaporative coolers on electricity for operation is a severe limitation for their usage in Nigeria due to challenges associated with electricity provision. Consequently, devices that are either energy independent or raw energy dependent will provide a more reliable option. The present work is aimed at harnessing raw solar radiation for cooling. A range of designed and fabricated prototype evaporative coolers were employed for which analysis were conducted to study the effect of varying certain parameters against a controlled condition. Attempt was made to utilize the device such that a temperature drop low enough to effectively preserve perishables without employing external energy sources, pumps or converters was attained. The performance evaluation yielded a temperature drop of at least 6 °C from the ambient. Potentially, this device shall be suitable for the preservation of perishable edibles.
Keywords: Solar radiation, evaporative cooling, temperature drop, ambient temperature.
