温湿度独立控制空调系统中独立新风系统的研究（2）: 送风参数的确定
Dedicated outdoor air system in the THIC air-conditioning system (2): Determination of supply air parameters
摘要：
介绍了新风量和送风含湿量的确定流程。以一个实际算例为基础，计算了各功能房间的湿负荷，分析讨论了新风量和送风参数确定时需要注意的问题。结果表明，对于人员密度较小的房间，必须考虑新风渗透产生的湿负荷；室外新风含湿量、平均风速及围护结构门窗密封性能和建筑高度对新风渗透产湿量均有显著影响。
Abstract：
Presents the determination process of outdoor air volume and humidity ratio of supply air parameters. With a practical building model, calculates the moisture load of each functional room. Gives the important suggestions for determination of outdoor air volume and supply air parameters. The results show that the moisture load from outdoor air infiltration in low occupant density room should be considered. Additionally, the outdoor humidity ratio and average wind speed, the air tightness of building envelope and the height of the building have significant effects on the moisture load from outdoor air infiltration.
