| 目的 以某电子方舱为研究对象，分析在现有结构条件下，空调所提供的冷量能否满足舱内电子设备正常工作要求和人员舒适要求。方法 分析和研究舱内的传热问题，采用FLUENT软件，并结合κ-ε两方程紊流模型与SIMPLE算法对方舱内的热环境进行三维数值模拟。结果 在保证空调送风温度和速度不变的前提下，送风角度分别为30°和0°时，都能基本保证电子设备正常工作要求和舒适性要求。当送风角度为30°时，方舱降温效果较好。结论 通过分析得到方舱制冷系统设计的不足之处，并提出了改进制冷系统冷气通路的方法，对今后方舱的制冷系统设计改进具有指导意义。 |

| Objective To analyze whether the cooling capacity provided by air conditioner under existing structure conditions meet requirements on normal working of electronic equipment and personnel comfort in the shelter. Methods Heat transfer in the shelter was analyzed and researched. Based on FLUENT software, and in combination with κ-ε two equation turbulence model and SIMPLE algorithm, a simulation of thermal environment in the shelter was established. Results If the temperature and speed of supply air were kept unchanged, the thermal environment in the shelter could meet the heat dissipation requirements of electronic devices and the comfort for operators with the blow angle 30 and 0, but the effect is better with the blow angle 30. Conclusion Shortages in design of refrigerating system for shelter can be obtained by analysis and the methods for improvement of the refrigerating system are proposed. It is important for the design and improvement of the shelter in the future. |
