摘　　要：地下水电站厂房内的热湿环境对工作人员身体健康以及设备安全运行有着重要影响。针对贵州某水电站进行了全年4个典型季节的地下厂房内热湿环境现场测试,发现该水电站地下厂房主要洞室全年干球温度10.2~26.7℃、相对湿度44.0~94.5%;热湿环境状况总体较好,但部分季节、部分洞室存在空气相对湿度偏高,部分低温设备及管道壁面存在不同程度“结露”现象。通过对地下厂房热湿环境存在问题的理论分析,提出了针对性的通风除湿改进方案,可以为类似水电站地下厂房的热湿环境调控提供一定的工程参考。The thermal environment of the underground powerhouse in hydropower station has a significant impact on the health of the staffs and the operation of the equipments.This paper presents on-site tests of thermal environment for four typical seasons throughout the year at a hydropower station in Guizhou.The results show the yearly air temperature is 10.2~26.7℃and the relative humidity is 44.0~94.5%for the main plants,which indicates the integral thermal environment is in good condition.However,some plants have the problem of high relative humidity in part seasons.Another problem is the dewing phenomenon on the low temperature equipments and pipes.The paper presents the improved plan for the ventilation based on the theoretical analysis of the thermal environment problems mentioned above.The conclusions can provide references for the thermal environment similar to the underground powerhouse in hydropower station.
