| Abstract: |
| 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. |
