Abstract
This paper presents a theoretical investigation of thermal and physical properties of a phase change material (PCM) consists of paraffin wax with 5% aluminum powder, this composite used as a thermal storage compound in a solar air heater, the compound supposed be encapsulated in cylinders as a solar absorber in cross flow of pumped air. An indoor simulation supposed that the PCM initially heated by solar simulator until liquid phase temperature (50°C) while the pumped air over the cylinders at room temperature (28°C), results show that the air temperature gained due to thermal energy discharge process decreases with increasing of air mass flow rate, and the freezing time for this compound takes long time interval for the lower mass flow rates.
