水电站地下厂房通风排热能效测试与分析

Test and Analysis on the Efficiency of Ventilation and Heat Discharge in Underground Workshop of Hydropower Station

本文根据该地下水电站功能建筑的布局和通风通道的设计,结合水电站的运行特点,在地下厂房空调系统关闭状态下,对主要通道的温湿度及风量、处于开启状态的风机的总输入功率、工作场所温度、相对湿度、风速、各风口的风量进行测试,评估自然风对厂房内部功能装置的排热能力和功能房的温湿度调节作用。结果表明,进风段洞室引入室外空气具有良好的降温效果,有助于厂房段的通风排热,并建议类似厂房可在建成初期的几年内通过自然风对厂房进行排热和温湿度调节。

According to the function of the underground hydropower station building layout and the design of the ventilation channel, combining with the characteristics of the operation of the hydropower station and the underground workshop air conditioning system is closed, the main channel of temperature and humidity and air volume, the total input power of the fan in an open position, temperature, relative humidity, wind speed, the workplace tuyere air volume testing, evaluation of natural wind device of plant internal function of the heat removal capability and function of room temperature and humidity. The results show that the introduction of outdoor air intake section cavity has good cooling effect, help workshop section of the ventilation heat, and suggested a similar factory can be built in the early a few years by natural wind exhaust heat and temperature and humidity control was carried out on the plant.
