The main feature of the turbulence clean room is that the flow cross section of the air flow is changing from the flow to the outlet (from the air supply outlet to the return air inlet), and the clean room section is much larger than the air supply inlet section, so it cannot form uniform airflow in the full-chamber section or in the full-chamber working area section.Therefore, the streamlines behind the air supply port have large or increasingly large angles between each other, the radius of curvature is small, the airflow cannot flow in a single direction in the room, will collide with each other, there will be backflow, vortex generation.The essence of the flow state of the turbulence clean room is: abrupt flow;Non-uniform flow.


This is a more accurate and comprehensive description of turbulent clean rooms than turbulence.Turbulence depends mainly on the Reynolds number, which is mainly affected by the flow rate. However, if a high-efficiency filter is used to top the air supply, all the above results will be produced even if the flow rate is extremely low, because it is a sudden flow and non-uniform flow.Therefore, in this case, there is not only mixing between flow layers due to turbulent flow, but also mixing of large reflux and vortices within the whole compartment.


So, in a nutshell, the role of turbulence clean room principle is: when a clean air from the air supply outlet into indoor, rapidly spreading around, mixed, at the same time almost the same amount of air flow from the inlet line to walk, the clean air dilution to indoor air pollution, the original high dust concentration of diluted in indoor air, always a balance.So the faster and more uniform the flow, the better the dilution.
