Airflow in a multi-zone building can be a major cause of pollutant transfer, excessive energy consumption, and occupants discomfort. The key to monitoring airflows and mitigating related problems is to obtain a comprehensive understanding of pressure relationships within the buildings. This study proposes a visualization method for representing pressure distribution within a multi-zone building by using a novel pressure-sensing system. The system consists of a Master device and a couple of Slave devices that are connected with each other by a wireless sensor network. A 4-story office building and a 49-story residential building were installed with the system to detect pressure variations. The spatial and numerical mapping relationships of each zone were further determined through grid-forming and coordinate-establishing processes for the building floor plan. Lastly, 2D and 3D visualized pressure mappings of each floor were generated, illustrating the pressure difference and spatial relationship between adjacent zones. It is expected that the pressure mappings derived from this study will allow building operators to intuitively perceive the pressure variations and the spatial layouts of the zones. These mappings also make it possible for operators to diagnose the differences in pressure conditions between adjacent zones and plan a control scheme for the HVAC system more efficiently.
多区域建筑中的气流可能是污染物转移、能源过度消耗和居住者不适的主要原因。监测气流和减轻相关问题的关键是全面了解建筑物内的压力关系。本研究提出了一种利用新型压力感应系统表示多区域建筑内压力分布的可视化方法。该系统由一个主设备和几个从设备组成，通过无线传感器网络相互连接。在一栋 4 层办公楼和一栋 49 层住宅楼中安装了该系统以检测压力变化。通过网格形成和坐标建立过程进一步确定了每个区域的空间和数值映射关系，以构建建筑平面图。最后，生成了每个楼层的 2D 和 3D 可视化压力映射图，说明了相邻区域之间的压力差和空间关系。预计本研究得出的压力映射图将使建筑运营商能够直观地感知压力变化和区域的空间布局。这些映射图还使运营商能够诊断相邻区域之间的压力条件差异，并更有效地规划 HVAC 系统的控制方案。
