某抽水蓄能电站地下厂房热湿环境测试分析

水电站地下厂房的通风空调系统对维持厂房内的热湿环境，使其满足人员工作及设备运行的要求有着重要作用。为了对某抽水蓄能电站地下厂房的热湿环境进行评估，对主厂房各层空间空气的热湿参数及通风量进行测试，并结合室外天气状况得出室外天气对厂房内的热湿环境的影响。在测试过程中发现，其蜗壳层设备及管路表面结露问题严重。根据对结露现象的分析，提出相应的解决方案，为水电站地下厂房的热湿环境的调控提供参考。

Test analysis of thermal and humid environment in an underground pumped energy storage hydro power plant

Underground hydro power plant＇s ventilation and air-conditioning systems to maintain thermal and humid environment is important to meet personnel working re- quirements and equipment operation. In order to evaluate the thermal and humid environ- ment of an underground hydro power plant, different layers of thermal and humidity of air space and ventilation combined with outdoor weather conditions are tested and analyzed. It is found that condensation on volute equipment and piping surfaces is a serious problem. Based on the analysis of condensation,appropriate solutions are proposed as a reference for the adjustment of thermal and humid environment of underground hydro power plant.
