The dynamic thermal history of storage product system is related to the insulation and also to the inertia. Use a new porous media doped with nanofluid PCM to improve the system efficiency. The analysis of the porous sponge thickness with 8 mm, 16 mm and 20 mm, the integrated nanofluids with 0.1%, 0.15% and 0.2%, the mass of the PCM and the initial temperature of the stored product with -1°C, 4°C, 12°C is achieved in order to underline the advantages of the new saturated porous media (sponges) with the phase change material (PCM) /Al2O3-H2O nanofluid. The carrots are used as the experimental object in the experiments by orthogonal method. And the integral value of average temperature of the air in the box is an index to judge the effect of cool storage. The transportation temperature and duration are mainly affected by the pre-cooling temperature of products, the storage materials, the nanofluids mass fraction, the thickness of porous sponge. Compared with range values, the optimal combination of all the factors for the effect of cool storage is as following: the thickness of porous sponge of 20 mm, the mass fraction of 0.2%, the mass of cold storage materials of 0.4 kg, and vegetables pre-cooling temperature of 4°C . Under constraint of mass (or volume) transportation we demonstrate that the thickness of sponge of 16 mm instead of 20 mm, and nanofluids mass fraction of 0.15% instead of 0.2% could be enough. The equivalent variable is defined basing on theoretical basis to interpret the experiment and analysis.
