Effect of thermal storage on crop drying system : A periodic analysis

This communication presents the periodic analysis of a ground air collector with reflector and crop drying chamber. The effect of thermal storage, collector length, depth of the plane of heat retrieval, the flow rate on the useful energy gain and crop temperature has been studied. Numerical computation has been carried out for the typical day of the month of June and December for Delhi climatic conditions. It is observed that there is a significant phase shift 10-12 h due to storage effect.
