Latent thermal energy storage for refrigerated trucks

Systematic Opportunity Scan of Energy Recovery Technologies Applied to Trucks with Electric Refrigerated Units

“…Calati et al [56] present that 40% of the total amount of energy required for the transportation of refrigerated food is consumed by the refrigeration system. Therefore, the research presented by the researchers is justified based on the growth of refrigerated food transportation, requiring systems that guarantee the temperature of the food within a certain range.…”

Thermal Storage Based on Phase Change Materials (Pcms) for Refrigerated Transport and Distribution Applications Along the Cold Chain: A Review

“…Similar to [91], Calati et al [17] modelled a 2D section of a traditional European refrigerated truck insulation wall which consisted of a cm Poly-Urethane foam layer wrapping a PCM layer with thickness ranging from 0.5 to 2 mm, as depicted in Fig. 13.…”

“…A different PCM location was investigated by Copertaro et al [83]. In [17] and [91] the PCM layer faced the refrigerated space, whilst in [83] it was applied to the external side of a traditional 20 ′ ISO refrigerated container. The authors aimed at analyzing the advantages in terms of energy need reduction due to the application of the new container envelope.…”

“…Moreover, five different exposures were considered: north, south, east, west, and horizontal. As done by Calati et al [17], the solar radiation was also considered. Compared with a traditional container, the authors evaluated the heat load peak and daily energy rate reductions to ensure the temperature inside the refrigerated space to be maintained at 0 • C. The internal air temperature was set at 0 • C, consequently, suggesting the adoption of an active refrigeration unit if considering a real application.…”

“…The LTESs have already found application in many different contexts as reviewed by Mobedi et al [10]. These applications range from high temperature industries (electricity generation and waste heat recovery, [11]), medium temperature applications, from thermal management of electronics and electric vehicle batteries to buildings ( [12,13,14]and, finally, low and very-low temperature applications such as HVAC systems ( [15,16], Botcher in [10]) or applications for the cold chain [17]. An ideal PCM should have a suitable phase change temperature along with high thermal conductivity and latent heat.…”
