Numerical Simulation of Small Cold Storage
The airflow change in cold storage were simulated by FLUENT under following three conditions, pre-cooling, stop to defrost and switch cold storage door. The result shows that the pre-cooling wind speed should be chose reasonably while guarantees the pre-cooling effort, hot air defrost had a favorable defrosting performance, and it is essential to seek optimal defrosting time according to the frost thickness and energy consume. The temperature field near the switch door was analyzed, and the temperature gradient near the switch door is considerable, but the outdoor air can be obstructed by increase air curtain.
