      If you’re using this type of louver grille for supply air then yes, same way to calculate. But usually supply air we use ceiling diffuser and those type need to select from the manufacturer’s data sheet.

    Good Morning, at the end of your presentation on grills you commented on dealing with noise from air handlers at the grill, which of presentations were you referring to. Thank you

    Amazing video. I'm not even in HVAC and I used it to calculate a decorative grill size. I'm pushing the 800 fpm limit. Other than noise, is there a risk of my decorative cover blocking too much air to the unit?

    • @aircondlounge
      @aircondlounge  8 месяцев назад

      Thanks. Other than noise, pushing the FPM higher will lead to higher pressure drop which is the air resistance that could slow down the AC fan speed (which reduces the overall airflow). However, we’re talking about prolonged length like a duct. One or two grilles that increases from 500 to 800 FPM wouldn’t have a noticeable difference.

      @@aircondlounge what about if the decorative grill is used to replace the air return grill cover? Am I going to starve the furnace from pulling in enough air? What are the risks I run here?
