Study on the Temperature Field inside Refrigerated Containers

Abstract

With the development of food industry and food refrigerated transport, all kinds of refrigerated containers are becoming more and more popular. But the decay of perishable food takes place often due to improper loading and unreasonable design of air flow organization. Based on analysis, experiments and simulation with Fluent software, this paper studies the temperature field and air flow inside the refrigerated container in certain loading conditions. The results show that different inner temperatures need different air blowing-in velocities in order to obtain more uniform temperature field. And the blowing-in velocities have the different influences to different positions inside the container. The increase of blowing-in velocity is beneficial to the uniformity of the temperature field. The conclusions and suggestions are of reference value to the design and operation of refrigerated container.
