Abstract:
Thermal comfort has a great influence on the productivity and satisfaction of indoor building occupants. In some developing countries, the realization of thermal comfort through the use of refrigerated-based air conditioning systems is largely impeded by poverty and epileptic power supply. Also, the use of some refrigerants has adverse effect on the environment. Evaporative cooling systems are viable options for achieving thermal comfort because, apart from their low cost and power requirement, they are environmentally friendly. This paper attempts to determine the viability of using evaporative coolers to achieve human thermal comfort in several Nigerian cities characterized by different climates using the feasibility index method. Employing the concept of the feasibility index reveals the suitability of using evaporative coolers in Maiduguri, Jos, Sokoto and Yola while Enugu and Port Harcourt are not recommended for the use of evaporative coolers. Evaporative coolers are therefore suitable alternative to refrigerated-based air conditioning systems for achieving human thermal comfort in these areas and in similar areas with high evaporative cooling potentials.
