| 摘 要： | 建立了冷库地坪通风防冻系统的三维稳态传热数学模型，对传热模型进行了合理的简化，根据系统的传热过程确定了传热模型的定解条件，利用PHOENICS软件对通风系统在不同通风流速下的传热模型进行了数值模拟分析。结果表明，通风流速对冷库地坪通风防冻系统的传热性能有一定程度的影响。指出了通风管间距为1．5m时较适宜的流速。

| Abstract: | A 3-d steady heat transfer mathematical model of cold storage floor anti-freezing ventilation system was set up and simplified reasonably. And according to the process of the heat transfer, the calculation conditions of the model was defined. Then the temperature field of the system was simulated and calculated under different ventilation flow speed by PHOENICS. The results indicated that the effect of ventilation flow speed was limited on the thermal performance of the system. And the proper ventilation flow speed was also pointed out when the spacing between pipes was 1.5m. |
