摘　　要：地下厂房热湿环境分布规律的研究对电站运行具有重要意义。利用CFD方法综合考虑室外天气、室内热源和室内湿源对热湿环境的影响后进行数值模拟并通过发电机层离线和在线监测结果验证了仿真精度。将仿真结果用于研究发电机层的热湿环境分布规律以及分析气流组织的热舒适性参数。结果表明:3种气象条件下的热湿环境参数分布相似,温度场分布均匀故温度不均匀系数数值较小,速度场和湿度场数值变化明显,因此速度不均匀系数较大,3种天气条件下的能量利用系数均较大,反应出其具有较好的节能潜力。The analysis of thermal-humid environment distribution of underground hydropower station is of great significance for plant operation.This paper,by using CFD considering outdoor weather,indoor heat and wet source,studies the distribution law of thermal-humid environment and through online and offline monitoring results of generator layer which shows simulation precision.The results of simulation is used to investigate the distribution of thermal-humid environment of the generator layer as well as the analysis of thermal comfort parameters of air distribution.Results show that the three kinds of meteorological parameters of thermal-humid environment under the condition of similar distribution,uniform temperature field distribution results in uneven temperature coefficient value,velocity field and humidity field changes obviously,so the speed of non-uniform coefficient is large,three weather conditions of energy utilization coefficient are large that reflects better energy saving potential.
