Air-conditioned room pressure difference and air balance design of passive ultra-low energy residential buildings
摘要：
被动式超低能耗居住建筑是提升我国居住建筑节能水平和室内环境的重要途径，但由于国内目前工程设计实践较少，现有工程的通风系统存在一定问题。在国内外标准的基础上，通过2个被动式超低能耗居住建筑的通风系统设计和性能实测数据，采用建筑围护结构整体气密性的空气渗漏量模型，分析了其空调房间与室外或走廊等相邻区域的压差值，以及新风系统风量平衡的设计应用，探讨了现行标准对被动式超低能耗居住建筑空调房间压差值和风量平衡设计的适用性。
Abstract：
The passive ultra-low energy residential building is an important way to improve the energy saving level and indoor environment of residential buildings in China. However, due to the current few engineering practices, the ventilation system design of existing projects has certain problems. Based on the domestic and international standards, through the ventilation system design and performance measurement data of two passive ultra-low energy residential buildings, adopting the air leakage model of building envelope, analyses the pressure differences between air-conditioned rooms and the adjacent areas such as outdoor or corridors, and the design application of air balance of outdoor air systems. Discusses the applicability of current standards to the air-conditioned room pressure difference and air balance design in passive ultra-low energy residential buildings.
