摘　　要：为研究云南干河泵站地下厂房通风系统方案的可行性,以数值模拟为基础、相似理论为依据,确定各种比例尺,建立了泵站地下厂房通风系统1/10的缩尺模型.进行了不同季节、不同送风温度、不同机组运行台数共9种工况的模型试验.测试了地下厂房各区域室内参数,对试验数据进行了处理与分析.试验结果表明,在最高送风温度24.5℃时,厂房内夏季最高温度为29.46℃,平均温度为27.72℃,满足相关设计规范要求,泵站通风系统方案可行.在部分机组运行及过渡季节时,室内温度更低,通风系统可采用变风量运行,进一步实现节能.A 1/10 scale model for the ventilation system of the underground powerhouse of Ganhe Pum- ping Station was established on the basis of numerical simulation and similarity theory to study the feasibil- ity of the pumping station＇s ventilation system. The model tests contained 9 different working conditions, such as different seasons, different supply air temperatures and different numbers of operating units. The interior parameters of all regions in the underground powerhouse were tested, and the test data were ana- lyzed. Experiment results have shown that the highest and the average interior temperature is 29.46 ℃ and 27.72 ℃ respectively in summer when the supply air temperature reaches 24.5 ℃. The scheme for the ventilation system meets the requirements of relevant standards. The indoor temperature is lower in transi- tion seasons and in partial loading condition. Therefore, VAV system can be used in the ventilation system in order to achieve further energy saving.
