摘　　要：在倡导节约能源的今天,主动式冷梁作为一种新型的空调系统末端以其舒适性、节能性受到了广泛关注。而评价主动式冷梁效果的一个重要指标就是它的诱导比。借助于FLUENT软件模拟了在不同一次风量下的型号为巴科尔AIR-FIT 2600主动式冷梁的诱导比,将冷梁的模型做出简化并且详细介绍了该模拟过程。模拟结果表明,主动式冷梁的诱导比随着一次风量的增大而增大,但是当一次风量达到一定风量之后,主动式冷梁的诱导比增长的速率开始趋于平缓。并针对此结果做出了分析,为主动式冷梁的一次风量的选取提供参考。Nowadays,the energy conservation is advocated,the active chilled beam as a new type of air conditioning system,is widely concerned on its comfort and energy efficiency.The induction ratiois a crucial index to evaluate the effect of active chilled beam.With the FLUENT software,the induction ratio of the model of Barcol AIR-FIT 2600 active chilled beam is simulated under different primary air flow,simplifying the model of the chilled beam and introducing the simulation process in details.The simulation result shows,the induction ratio of the active chilled beam increases with the increase of the primary air flow,but when primary air flow reaches a certain value,the growth rate of the induction ratio of the active chilled beam begins to flatten out.The result is analyzed and provides a reference for the selection of the air flow of the active chilled beam.
