In Ghana, the production, consumption and commercialisation of mangoes are substantially low. The fruits are highly perishable and require storage temperatures of 10-15oC, but most mango producing areas in Ghana are remote, poor and do not have access to electricity and so cannot use conventional cold storage systems. The wet bulb temperatures in these areas are between 14 and 27oC; and relative humidities vary between 16 and 77%, so a combined desiccant dehumidification and evaporative cooling system has been designed and used at these areas. The system consists of the storage chamber, dehumidifier, heat exchanger and saturator. Analytical models of these components have been developed, the components designed and experimental procedure explained in this paper. Three key assumptions were made in solving the model equations with a computer simulation programme, namely no heat transfer through the walls, no water loss by drift and steady flow conditions. The system__ampersandsignrsquo;s performance was found to be dependent on incoming air conditions and water flow rate and its overall performance produced a minimum cooling of 0.31 tons and maximum cooling of 2.00 tons for water flow rates of 0 and 0.252 l/s respectively. The observed storage temperature of 12oC and relative humidity of 90% were found to be conducive for the long term storage of mango.
