Abstract
In this paper, a comparative study is conducted on the performance of an indirect solar dryer using a solar air heater with a phase change material (PCM) as thermal energy storage (TES). The solar dryer was tested for drying banana crops in Baghdad, Iraq, for two airflows: with a constant flow rate and an automated flow rate control. The parameters like solar radiation, difference in the air temperature across the heater, heater thermal and drying efficiencies, and PCM freezing time are analyzed. The PCM stores thermal energy during the day, releasing it after dark to run the dryer for 5–6 h in the case of the constant flow and 8–9 h in the case of the automated airflow. The results showed a 15% increase in the average drying efficiency and a 31% increase in the average collector efficiency under automatically controlled airflow compared to the constant airflow.
