Abstract

In order to reduce the influence of defrosting heat on the temperature fluctuation of the cold storage, this experiment uses two cooling fans in parallel on the basis of continuous defrosting, and studies the influence of defrosting heat on the temperature fluctuation of the cold storage under four working conditions: The resultsindicate that the average temperature of each section of the empty storage is always higher than that of the top cold storage in the process of defrosting; the temperature fluctuation of the top cold storage is 2.52 ℃ and 2.94 ℃ lower than that of the empty storage under the frost and no frost conditions, and the energy consumption of defrosting is 1.36% and 1.81% lower than that of the empty storage, respectively. The results show that the cold storage plate on the top of the cold storage can effectively reduce the temperature fluctuation during defrosting, which is of great significance to ensure the quality of food stored in the cold storage.
