Ceiling Fan Air Supply vs. Ordinary Air Inlets: Principles & Core Differences
\nI. Core Differences in Air Supply Principles
\n1. Ceiling Fan Air Supply (Laminar Flow Type)
\nProcess: Collecting air and stabilizing pressure \u2192 Multiple-stage filtration \u2192 Rectification and uniform flow \u2192 Vertical Unidirectional Laminar Flow
\nThe air first enters a large volume static pressure chamber, where the high-speed air slows down and the overall pressure is balanced, completely eliminating turbulence;
\nThen it passes through primary \/ intermediate \/ high-efficiency filters for deep purification;
\nNext, it is further rectified by orifice plates and uniform flow membranes, ensuring uniform wind speed across the entire surface;
\nThe air flows downward in a low-speed vertical laminar flow (0.30 – 0.45 m\/s) in a parallel manner, with no cross-flow or swirling.
\n2. Ordinary Air Inlets (Blade \/ Diffuser Inlets)
\nProcess: Direct air discharge \u2192 Turbulent diffusion
\nThere is no independent static pressure chamber. The air flow directly reaches the inlet through the duct, and the distribution of wind pressure and speed is uneven;
\nMostly equipped with simple filters or no high-efficiency filtration, the purification capacity is weak;
\nThe wind direction is changed by blades and diffuser plates, and the air flow presents a chaotic vortex and turbulent form, spreading and swirling in all directions;
\nThe air flow speed is relatively high, and the flow lines are disordered.

III. Summary in One Sentence
\nSupply air ceiling: First stabilize pressure, then purify, and finally rectify. Achieve high cleanliness levels through stable laminar flow;
\nOrdinary air outlet: Air is directly sent out through the duct, achieving ventilation and air exchange in the space through turbulent mixing.<\/p>","protected":false},"excerpt":{"rendered":"
