In the quest to optimize energy efficiency in cold-chain transportation, a groundbreaking study led by Guo Jiaming has shed new light on the potential of high-reflectivity insulation materials. Published in *Zhileng xuebao* (translated as *Journal of Refrigeration*), the research delves into the thermal insulation characteristics and energy consumption of refrigerated trucks, offering promising insights for the energy sector.
Guo Jiaming’s study focused on enhancing the thermal insulation performance of refrigerated trucks, a critical factor in reducing energy consumption and operational costs. By employing high-reflectivity insulation materials, the research team conducted comprehensive tests to analyze heat flux, air cooling rates, and temperature uniformity within the truck compartments.
The results were striking. The application of these advanced insulation materials reduced the peak temperature of the external wall surface by a significant 23.6°C. This reduction translated into a substantial decrease in heat transfer into the compartment, with heat flux reduction rates ranging from 16.7% to 26% at a set refrigeration temperature of 5°C. In the absence of refrigeration, the heat flux reduction was even more pronounced, at 46.3%.
“These findings demonstrate the immense potential of high-reflectivity insulation materials in improving the energy efficiency of refrigerated trucks,” said Guo Jiaming. “The materials not only enhance temperature uniformity but also allow the refrigeration system to reach and maintain the desired temperature more effectively.”
The study revealed that the insulation materials improved the temperature uniformity of the external wall of the compartment to 1.12 and the internal uniformity to 1.68. This enhancement led to a 9.1% reduction in the operating frequency of the compressor, resulting in significant energy savings and improved energy efficiency.
The implications of this research extend beyond refrigerated trucks. The findings are relevant for various facilities with insulation requirements, such as granaries and cold storage facilities. As the energy sector continues to seek innovative solutions to reduce consumption and lower costs, Guo Jiaming’s study offers valuable insights into the future of energy-efficient cold-chain transportation.
“Our research provides a new perspective on how advanced insulation materials can revolutionize the energy efficiency of cold-chain logistics,” Guo Jiaming added. “This is just the beginning, and we are excited about the potential applications and further developments in this field.”
As the industry continues to evolve, the integration of high-reflectivity insulation materials could pave the way for more sustainable and cost-effective cold-chain transportation solutions. The study published in *Zhileng xuebao* serves as a testament to the ongoing innovation in the field, offering a glimpse into the future of energy-efficient logistics.
