Numerical simulation of air flow and heat transfer in air refrigerated containers using clean energy technologies

Abstract

Air refrigerated containers are important links and key equipment for air cold chain transportation. The refrigerated container cools the goods through the cold air circulation in the container to achieve the purpose of refrigeration. The key to the design of aviation refrigerators lies in the numerical simulation of the cold air flow and temperature distribution in the containers to determine the best air duct design and optimal air outlet arrangement. This article briefly analyzes the structure of the air refrigerated container, establishes the mathematical and physical models for numerical analysis, and then analyzes the two methods. At the same time, temperatures are tested in physical container with temperature measuring devices and conducts a comparative analysis with numerical simulation. The results show that the existing top on the basis of the air supply, assign a flow channel to each small tuyere and remove the small tuyere beside it. This situation is better for both flow and heat transfer. Temperatures in tests are similar with numerical simulation.
