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。
Describes the new air flow and air humidity determination process. Based on an actual example, the wet load of each functional room was calculated, and the problems needing attention when determining the fresh air volume and blowing air parameters were analyzed and discussed. The results show that the wet load caused by infiltration of fresh air must be taken into account in the rooms with small staff density. The outdoor fresh air moisture content, the average wind speed, the sealing performance of the windows and doors and the building height of the enclosure structure have a significant impact on the infiltration wetting capacity of fresh air.
