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.
