| 摘 要： | 介绍了一种下送风空调系统的设计方法,利用Airpak软件对该设计方法下的空调房间进行数值模拟分析。通过模拟结果得到,下送风空调房间在垂直方向出现温度分层现象,下部工作区温度较低,这使得下送风空调比传统全室性空调系统节能;下送风空调在下部工作区具有较好的热舒适性;下部工作区空气龄较小,能够改善工作区的空气品质。模拟结果证实了该设计方法可靠有效。

| Abstract: | A design method for under floor supply air conditioning system is introduced,and an air-conditioned room designed by the method was analyzed through numerical simulation with software Airpak.Three conclusions are drawn from the results: air in the under floor air supply air-conditioned room shows clear temperature stratification in the vertical direction with lower temperature in the working area beneath,which makes it possible to save more energy than conventional whole room air conditioning system;human thermal comfort is improved in the working area beneath;air quality in the working area is improved as a result of lower air age.Simulation results prove that this design method is efficient and reliable. |
