Abstract: A product performance test method and system are provided. The product performance test method includes: at least testing a specific heat capacity C of a heat storage material of a sample, a heat transfer coefficient K, an energy efficiency ratio E of a refrigeration system, and a mass m of the heat storage material contained in the sample to detect a performance level of the sample. The method provided tests four key factors: the specific heat capacity C of the heat storage material of a product, the heat transfer coefficient K, the energy efficiency ratio E of the refrigeration system, and the mass m of the heat storage material in a box.
