| Abstract: |
| To simultaneously deliver multi-categories of fresh products at multiple storage temperatures and to ensure the continuous operation of the cold chain for “the last kilometer”, the development of appropriate cold chain distribution equipment is crucial. Through the e-commerce market research of fresh products and the analysis of distribution demand, a cold thermal energy storage delivery box with multiple storage temperatures was developed, following the relevant standards. The details of structure design, temperature zone distribution, thermal insulation materials, and cold thermal energy storage material, were presented. The performance test of the heat transfer coefficient was also conducted. The test results show that the thermal insulation structure is stable, and the total heat transfer coefficient of the box is 0.68 W/(m2?K), which satisfies the technical requirements of ordinary temperature refrigerated transport vehicles. |
