Calculating floor area for install Ventilator Fan

Calculating floor area for install Ventilator Fan

For Model : A-14S, A-18S, A-22S, A-22, S22, A-25S, A-25, S25, A-30 และ A-39

  1. Calculating the volume of the building
    Formula (put the size of the building) Wide x Long x High
      90 x 120 x 5
    Volume of the building = 54,000.00 m2
  2. Calculating the volume of air must transplant out

    Select the deployment to determine the amount of air to flow out of the building by the AIRCHANGE / hour which is defined as operating conditions
    Style deployment
    (installation point)
    Number AIRCHANGE / HR.
    Warehouse 5-7.5
    Repair plant / Factory 10-15
    Machinery room/ Plant 15-25
    Kitchen (with a lot of heat). 25 or more
    Spray Booth/ Dry Booth 30-100
    Formula Volume of building x AIRCHANGE / HR. ÷ 60 minutes
      54,000.00 x 25 ÷ 60
    The air must transplant out = 22,500.00 CMM
  3. To find the number of fans that will be installed

    The ability of ventilation fan of each model is
    A-14S     =     33 CMM.
    A-18S     =     43 CMM.
    A-22S, A-22, S22     =     80 CMM.
    A-25S, A-25, S25     =     90 CMM.
    A-30     =     111 CMM.
    A-39     =     162 CMM.

    The formula for fan (Select models fan to be installed from the top) MODEL: A-25S (for example)
    The air must transplant out ÷ The ability of the fan required = The number of fans that will be installed.
    22,500.00 ÷ 90.00 = 250 set

    *** Calculating may vary depending on operating conditions. Each building has different conditions. ***
