Abstract
The use of a dehumidifier as a home appliance was advertised in one of the dailies. To investigate the feasibility of using dehumidifiers in Nigeria, fifteen-year dry-bulb temperature and relative humidity data for Ikeja and Ilorin were analysed to get the two-dimensional dry-bulb temperature/relative humidify data for the two locations. From the results, the average number of hours per year in the comfort zone defined by American Society Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) were found to be 182 and 1177 for Ikeja and Ilorin, respectively. It was also found that using a dehumidifier that takes the room air through only a dehumidification process (dry-bulb temperature remaining constant) to bring the relative humidity below 70 % can bring additional 76 %and 58 % of the 8766 hours in a year into the comfort zone at Ikeja as representative of coastal areas and Ilorin to be representative of locations further from the coast in the rest of southern states and parts of the middle-belt, it can be concluded that the use of dehumidifiers is feasible for air-comfort in the southern states and southern part of the middle-belt in Nigeria. Dehumidifiers can also be used to bring relative humidity below 65 % required to grain storage even in the coastal areas. Therefore, a dehumidifier is a useful household appliance in the southern and middle-belt states.
