Effects of Switch Door on Temperature Field in Cold Storage Based on Numerical Simulation

Abstract

In this paper, the unsteady numerical simulation in the doorway was done, the unsteady temperature field in 30s, periods of opening and closing door was simulated, the results show that the outside air can quickly penetrate into the room and disrupt its temperature field during the process of opening the door, after closing the door, the air cooled quickly in the downside of the room, the upside cooled slowly. It shows that this process will cause the door cooling loss, air curtain at door and other measures should be taken for energy saving.
