In this work, an innovative insulated wall concept for refrigerated truck is proposed. A 2D transient numerical model of the truck cell is developed and simulated considering the solar radiation from 6 AM to 4 PM of a typical summer day in Vicenza (Italy). The innovative composite wall consists of a traditional polyurethane (PU) insulation layer wrapping a layer of PCM (reference melting temperature of 2 °C) with different thickness from 0.5 cm to 2 cm. The results confirm that the proposed solution is very promising because even the smallest thickness can assure an adequate temperature inside the cell for almost the entire simulated journey.
