摘要: |
为选择合适的汽车方舱空调系统和进出风模式,运用FLUENT软件,对升温、降温和考虑辐射3种工况进行仿真计算,得到相应的舱内速度和温度分布. 升温时,经过300 s舱内平均温度从243 K升到290 K;降温时,经过300 s舱内平均温度从343 K降低到302 K;降温时考虑辐射,经过264 s舱内平均温度从343 K降低到302 K. 对不同进、出风模式进行仿真计算,得到制冷(热)效果较好的进、出风模式. 结果表明:选择左进左出模式有利于利用方舱上层空间;选择右进右出模式有利于利用方舱下层空间;复杂进风模式的通风效果比简易进风模式优越;前出风模式比下出风模式优越. 上述结论为空调选择和进出风模式确定提供了参考依据. |

Abstract: |
Simulations on three kinds of working conditions (heating, cooling and radiation) and different kinds of air-inlet and air-outlet patterns to gain the corresponding distribution of air velocity and temperature inside the shelter were done with FLUENT software. The results indicated that: the cabin average temperature rose from 243 K to 290 K after 300 s when heated; the temperature reduced from 343 K to 302 K after 300 s when cooling; the temperature reduced from 343 K to 302 K after 264 s when considering the effect of radiation during the course of cooling. The results also indicated that: the average air velocity of left-in and left-out pattern was the biggest in the upper space of shelter, while it was the biggest in the lower space of shelter by choosing the right-in and right-out pattern; ventilating effect of complicated air-inlet pattern was better than that of simple air-inlet pattern, and the front-direction removal pattern was better than the down-direction removal pattern. |
