地下水电站主厂房通风空调系统设计风量的确定
Determination of design air volume in ventilation and air conditioning system for underground hydropower station
摘要：
归纳了地下水电站厂房的布置及其通风空调系统的通风流程特点，并分析了地下水电站厂房的通风与其他建筑的区别。总结了目前空气处理方案的8种类型，并阐述了系统设计风量的影响因素，推导出各种空气处理方案与通风流程所对应的系统设计风量及空气处理设备冷量的确定方法。建议实际工程中应根据室外进风参数、室内设计参数及厂内不同场所的余热比例等因素，合理选择空气处理方案和确定系统设计风量。
Abstract：
Summarizes the layout of underground hydropower station and characteristics about ventilation process, and analyses the differences between the ventilation system of underground hydropower station and that of other buildings. Summarizes eight types of air processing schemes, and expounds factors affecting the design air volume. Moreover, deduces the methods for determining the design air volume and air handling equipment cooling capacity corresponding to various air processing schemes and ventilation process. Suggests that a reasonable air processing scheme and design air volume should be selected according to the outdoor inlet air parameters, indoor design parameters and the proportion of heat from different parts in the actual project.
