Investigation on air age in a ventilated room with tracer gas technique |
| |
摘要 应用示踪气体测量得到了8种强制通风工况下实验小室中各种测点处的浓度衰减曲线，并计算出各测点的空气龄。实验结果表明，示踪气体用于强制通风研究时实验可重复性较好，实验结果正确合理，测得的空气龄反映了房间各点空气的新鲜程度，也提示了室内空气的流动形态。
关键词 示踪气体 空气龄 通风 实验
Abstract Obtains the decay curves of tracer gas concentration for eight mechanically ventilated cases in a test chamber, calculates the air age from the test data. It is shown that the experiments were done with good repeatability and the tested results of air age were reasonable, which in……
