尾水洞通风可作为水电站厂房的高效节能空调。建立了尾水洞通风系统热湿传递的简化模型，并在此基础上建立了小型试验装置，模拟了尾水洞通风系统中空气流动的热湿传递过程。该模型已被验证对实验和现场测试数据，它显示了良好的协议。该简化模型可用于水电站尾水洞通风系统全年热湿传递特性的预测，也可为水电站尾水洞通风系统的设计提供依据。
Tailrace tunnel ventilating can be used as a highly efficient and energy saving air conditioning for factory buildings in hydropower stations. This paper describes a simplified model of heat and moisture transfer for tailrace tunnel ventilating system with the assumption of isothermal boundary for tunnel wall, and constructs a small-scale experimental set-up to simulate the heat and moisture transfer process during the air flowing through the tunnel. The model has been validated against the experimental and field-test data, and it shows a good agreement. This simplified model is intended for use in annual performances prediction of heat and moisture transfer or provides the design tools for tailrace tunnel ventilating system in hydropower stations.
