Abstract


At present,it is urgent to find a development-sustainable air-conditioning mode to reduce building energy consumption.This air-conditioning mode should save energy and protect environment.Deep soil and underground tunnel has remarkable energy storage ability, which is also a natural and environment protecting renewable resource.Thus,widely attention of hydro power station air conditioning designer is drawn by underground tunnel and air supply tunnel.For the designers,the key is to find the methodology of utilizing the energy storage ability of underground tunnel and air supply tunnel,in order to actualize suitable air conditioning design of hydro power station indoor environment.In this paper,a field test and theoretical analysis is done on the tunnel ventilation pattern of Shisanling Hydropower Station.Based on the field test data,indoor temperature and relative humidity change regulation of hydro power station is discussed,while the indoor temperature and relative humidity modulation capability of the tunnel is worked out. Moreover,the energy change when air goes through the tunnel is calculated,in order to analyze tunnel energy saving potential.By building up the heat exchange model of hydro power station tunnel,the heat exchange theoretical function is figured out.Then,the notion and function of tunnel efficient and optimize heat exchange length is introduced respectively. The field test data indicate that these functions have high precisions.Erro is below 5%.By analyzing,wall temperature of Shisanling hydro power station tunnel is roughly remain at about 22.3℃.The inlet air can have a significant temperature change,when it goes through hydro power station tunnel or air supply tunnel.After that,the outlet air temperature is close to wall temperature.Erro is±1℃.Thus,tunnel air supply could provide the plant with favorable indoor environment,which meet the need of air conditioning requirement.It is also indicated that the influence of tunnel regulation ability on relative humidity is opposite to that on temperature.The field test of Shisanling hydro power station tunnel(deapth 250m),shows that the tunnel heat exchange is in the condition of constant wall temperature,which is proved by the accordance of theoretical function and field test data.
