Abstract :
In this study, we present thermal results related to the heating effect on the microclimate of a direct solar dryer (DSD). The heating effect is tested under two types of climatically different days: aclear day and a cloudy day. A comparison of the results of the numerical simulation and the experimental tests showed a good agreement and covered two types of heating systems: one radiative and the other convective. Their performance, which depends at the same time on the ambient climatic conditions and the thermal performance of the dryer, is decisive as to the advantage and the disadvantage of each and their appropriation to maintain an appropriate setpoint temperature.
