The HVAC diffusers shall be customized according to the opening size. In order to facilitate installation, the actual inner diameter (length and width) of the HVAC diffusers will be slightly less than the net opening size by 0.5-1.0 cm. Louver HVAC diffusers are widely used as air supply outlets in air conditioning systems. According to the use requirements, aluminum air volume regulating valves (miter gates) can be equipped behind the HVAC diffusers.
Used in heating and cooling air conditioning systems, can be installed on the side wall or ceiling. The vertical louver-type air outlet has a positive-pressure air conditioning room for automatic exhaust. Normally, the louver at the air outlet will naturally sag by its own weight to isolate the indoor and outdoor air exchange. When the indoor air pressure is greater than the outdoor air pressure, the airflow will blow the louver open and exhaust outwards. Conversely, when the indoor air pressure is less than the outdoor air pressure, the airflow cannot reverse into the room, and the air outlet has a one-way check function.
