Refrigerated transportation has a primary role in assuring quality and safety of perishable products. About 4million of refrigerated vehicles run worldwide. The energy requested for the foodstuff carriage only is about40% of the total energy consumed during the journey. Researchers have been putting their efforts in developinginnovative solutions to assure an adequate products transportation with lower environmental impacts. LatentThermal Energy Storage systems based on PCMs are a promising technology.In this work, the discharging phase of an insulated wall consisting of a polyurethane layer wrapping a secondone (0.5-2 cm thick) of PCM (2-5°C melting temperature) is analysed. 2D transient simulations are run byapplying a varying hourly solar irradiation of a typical summer day in Vicenza. The results reveal that theproposed design is very promising because even the smallest thickness can assure an adequate temperatureinside the cell for almost the entire operation.
