在一个名为个人微气候系统（PERMICS）的局部空调原型系统上测量了通风效果。在同时测量速度场和示踪气体浓度的基础上，引入了基于系统运行第一分钟示踪气体相对减少的新参数。商业计算流体动力学（CFD）软件的模拟结果验证了该参数的有用性。该参数可以快速测量通风系统的局部效率。
Ventilation effectiveness was measured on a prototype system for local air-conditioning named personal microclimate system (PERMICS). Based on simultaneous measurements of velocity field and of tracer gas concentration, a new parameter based on the relative decrease of tracer gas in the first minute of system operation was introduced. The usefulness of this parameter has been verified by simulation results from commercial computational fluid dynamics (CFD) software. This parameter makes quick measurements of the local efficiency of ventilation systems possible.
