Large Size Static Pressure Box Airflow Distribution Guodan Liu,Xinxin Wang,Xuan Wang, Feng Qi,Gang Wang , Songtao Hu Institute of Environmental&Municipal Engineering, Qingdao Technological University, Qingdao,266033, China E-mail: xinxin9882@126.com Keywords: Large size static pressure box; floor air supply systems; the way of ventilation; turbulent model; Abstract.
Static pressure box space size bigger, civil structure is complex, leading to the gas flow distribution in the complex, if processing is bad to can affect the uniformity of air supply[2].
The air distribution air conditioning system, using complex structure punching plenum ventilation engineering case is not much, at present there is no Uniform design codes and standards, and static pressure box airflow organization quality will directly affect the audience area ambient air quality and comfort, so if you can grasp accurately the static pressure and velocity distribution situation, will be to improve the air quality audience and comfort play an important role.
