The present study has been executed to clarify the advantage of using latent thermal storage integrated with a back pass solar air heater (SAH). The purpose of this study is to design, fabricate and evaluate the performance of SAH with integrated nanoparticles enhanced phase change material (PCM) absorber storage system. Two different of the SAH configurations have been designed and studied; without thermal storage and with thermal storage using paraffin wax as a PCM. Both configurations are fabricated and tested outdoor under the Iraq climatic conditions according to ASHRAE standard tests at different air mass flow rates. The experimental results show that improvement in the efficiency of the SAH integrated with storage compared to SAH without storage. Moreover, the discharging time of heat stored took 5.5, 5, 4.5 and 4 hours at the air mass flow rate 0.03, 0.04, 0.05 and 0.06 kg/s, respectively.
