In order to solve the problems such as short insulation time of the traditional fresh self - lift cabinet and more start and stop times of the compressor. In this paper, by means of numerical simulation and experimental verification, the temperature variation and temperature distribution in the storage compartment of fresh self-storage cabinet with or without cold storage plate are simulated respectively, and the influence of vacuum insulation panel embedded in the insulation layer of fresh self - raised cabinet on the temperature field in storage compartment was studied. The results show that the average temperature in the storage compartment of the cold-storage fresh self-lifting cabinet rises from the initial temperature of 4℃ to the compressor opening temperature of 8℃, which is 38% longer than that of the traditional self-extracting cabinet. In the 800s 1200s 1800s 3000s, the average storage temperature of the cold-storage self-extracting cabinet was 0.8℃, 0.9℃, 1.4℃ and 2.3℃ lower than that of the traditional self-extracting cabinet. Moreover, the storage time of fresh food storage grid embedded in VIP cabinet was extended by 50%
