Refrigerated truck as the research object, using the CFD numerical simulation software simulate the dynamic temperature field of refrigerated truck with a internally suction type air curtain, it emphatically analyzes the influence of the export velocity of the internally suction type air curtain to the refrigerated truck's heat preservation performance when door is opened. The results show that the suitable export velocity of the air curtain can improve the insulation performance of the refrigerated truck, but when the export velocity is too large, the opening of the air curtain not only can n...
