Central air-conditioning vents-double-layer louvered vents and advantages
The double-layer louvered air vent is equipped with two mutually perpendicular sheets, which are used to adjust the water temperature and the angle of the vertical sheets, expand the airflow dispersion surface, and change the wind direction. The width of the outer frame of the tuyere is also provided with a wide frame and a narrow frame, which are used for the specially requested ventilation system. The biggest feature is that it can be used together with the conditioning valve.
Central air-conditioning vents-single-layer louver vents and advantages
The single-layer louver tuyere can only adjust the wind direction either high or low, and the angle of the segment can either use the ABS plastic firm bracket between the blades. The blades of the single-layer louver tuyere can either be placed horizontally or vertically to control the deflection of the airflow. The biggest advantage is that the wind direction is relatively convergent, and the wind is relatively large.

Central air-conditioning vents-self-hanging louver vents and advantages
If the central air-conditioning vent is a self-hanging louver type, the louver of the air vent naturally sags due to its own weight. The central air-conditioning room with positive pressure actively exhausts the air, and the air-conditioning exchange between indoor and outdoor is blocked from the vertical. When the indoor air pressure is higher than the outdoor air pressure, the airflow will actively blow open the shutters and the airflow will be squeezed out. If the indoor air pressure is lower than the outdoor air pressure, the airflow cannot flow in the opposite direction. The biggest advantage is that it depends on the pressure to stop the deflection of the airflow.

Central air-conditioning tuyere-diffuser and advantages
The diffuser is to allow the air outlet and the direction of the wind to distribute dividends in multiple directions, so that it can be distributed evenly over a large area. The diffuser can be made into a square or rectangle either or according to the relevant request. The biggest advantage is that it makes the wind direction radiate a larger area, and the wind is evenly distributed, and it is also possible to use a regulating valve to control the size and speed of the overall air volume.

Central air conditioning air outlet—spherical adjustable air outlet and advantages
The spherical adjustable air outlet is a kind of air outlet that is similar to the nozzle type. The air flow is abnormally converged. The end of the nozzle is biased to supply air, but after the air flow radiates in and out, the adjustment can be stopped in the space at the top corner, making the air flow end the process. The valve is switched on and off to stop the conditioning. The biggest advantage is that it is suitable for high-speed air supply at the top of the Sage floor, similar to the airport terminal and other places.
