置换通风是近年来发展起来的新型通风方式 ,可将未经混合的清洁空气直接送入人体活动区 ,并达到节能的效果。对于水电站厂房发电机层机组较少、纵向长度不长的通风设计 ,可采用下进上排、纵向穿堂风的气流组织方式 ,并利用大坝灌浆廊道冷空气 ,可节省厂用电 ,达到较好的通风效果。经过在高坝洲水电站厂房中的实际应用 ,这种置换通风方式类似自然风 ,通风效果好且流场稳定 ,可供类似电站暖通专业设计参考 Displacement ventilation is a new type of ventilation developed in recent years. It can directly send un-mixed clean air into the human activity area and achieve energy saving effect. For the hydropower station plant generator layer less, long vertical length of the ventilation design, can be used into the row, the vertical wind through the hall organization, and the use of dam filling corridor cold air, electricity can be saved plant to achieve more Good ventilation effect. After the practical application of Gaobazhou hydropower plant in the plant, this replacement ventilation is similar to the natural wind, good ventilation and flow field stability, for similar HVAC professional design reference
