Latent Thermal Energy Storage (LTES) systems adopting Phase Change Materials (PCMs) have been proposed to be implemented along the cold chain over the last years. Hence, in this work, a novel insulated wall concept for refrigerated truck is proposed. A 2D transient numerical model of the truck cell is developed. Results are obtained considering the varying hourly 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 with different thickness from 0.5 cm to 2 cm. Three paraffin waxes with different reference melting temperature of 2°C, 4°C, and 5°C are studied. The results confirm the validity of our hypothesis because even the minimum thickness layer of PCM considered here can ensure an adequate temperature inside the cell for almost the entire simulated period.

Abstract
Latent Thermal Energy Storage (LTES) systems adopting Phase Change Materials (PCMs) have been proposed to be implemented along the cold chain over the last years. Hence, in this work, a novel insulated wall concept for refrigerated truck is proposed. A 2D transient numerical model of the truck cell is developed. Results are obtained considering the varying hourly 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 with different thickness from 0.5 cm to 2 cm. Three paraffin waxes with different reference melting temperature of 2°C, 4°C, and 5°C are studied. The results confirm the validity of our hypothesis because even the minimum thickness layer of PCM considered here can ensure an adequate temperature inside the cell for almost the entire simulated period.Pubblicazioni consigliate
