摘要：To investigate the effect of ventilation tube inside diameter on thermal performance of food refrigerated warehouse floor ant freezing mechanical ventilation system, a steady three-dimensional mathematical model of heat transfer is set up in this study. The calculation conditions of the heat transfer model are defined according to the reasonable simplification and heat transfer process. The temperature fields of this system are simulated and calculated by CFD software PHOENICS under different tube inside diameters, 250 or 300 mm. The results show that the effect of ventilation tube inside diameter is greater on thermal performance of food refrigerated warehouse floor antifreezing mechanical ventilation system. The proper tube inside diameter is pointed to be 250 mm for the food refrigerated warehouse floor with 1.5 m tube spacing.
