摘要:
以海滨城市典型综合管廊某通风段作为研究对象，建立适用于综合管廊通风换气、传热传质的三维非稳态数学模型，并分析该段管廊的流场、温度场、湿度分布等。研究发现，通风后管廊内湿度、温度由外部环境的空气状态和管廊的热力环境决定。在廊内高温报警工况下，当外界干球空气温度等于或低于35 ℃时，采取机械送排风可取得很好的降温效果。当管廊内温度低于外界空气露点温度时，在送风风机入口、低温壁面处易形成水珠/水雾，应予以关注。
Abstract:
A three-dimensional unsteady mathematical model for ventilation, heat and mass transfer of a ventilation section of a utility tunnel built in a coastal city was established, and the flow field, temperature and humidity distribution of the section of the utility tunnel were analyzed. After ventilation, the humidity and temperature were determined by ambient air state and thermal environment in the utility tunnel. In the case of high temperature alarm in the utility tunnel, mechanical ventilation could achieve a good cooling performance when the ambient air dry-bulb temperature was equal to or below 35 ℃. When the temperature in the utility tunnel was lower than the dew point temperature of the ambient air, water droplets and mist were easily formed at the inlet of the air supply fan and on the surface of low-temperature wall, which should be paid attention to.
