摘要
节点风压作为通风系统重要的参数之一,其计算方法和应用尚未引起足够的重视。以大气节点为参考点,采用广度优先算法累进计算通风系统中各节点的风压。以节点风压数据为基础,通过对通风网络图的节点号和风道号进行重新编码将节点号和风道号与其实际物理位置的风压关联起来,从而方便人们对通风系统的阅读、理解和记忆,更使得在复杂通风系统中搜索特定的风道和节点、判断风道位置的对错有章可循,有法可依。
As an important parameter of ventilation system, node pressure and its calculation method as well as its application have not attracted enough attention. Taking air node as reference point, breadth first search is adopted to calculate progressively the air pressure of each node in a ventilation system. Based on the data of node pressure, the numbers of each node and airway in a ventilation network graph are recoded to correlate the air pressure of their objective physical locations, thus can facilitate the reading, understanding and remembrance of a ventilation system. More importantly, this optimization method of recoding can make it well - regulated for operators to seek some airways and nodes and to judge their positions.
