Abstract

Forced or natural ventilation is the most common measure of frost heave protection for refrigerated warehouse floor. To optimize air velocity for the underfloor forced ventilation system of refrigerated warehouse, a steady state three-dimensional mathematical model of heat transfer is set up in this paper. The temperature fields of this system are simulated and calculated by CFD software PHOENICS under different air velocity, 1.5 m/s, 2.5 m/s or 3.5 m/s. The results show that the optimized air velocity is 1.5 m/s when the tube spacing is 1.5 m.
