Calculating floor area for install Agriculture Fan

Calculating floor area for install Agriculture Fan

For model : AV-J01040 (40") 1/2HP, AV-J01048 (48") 1HP และ AV-J01048 (48") 2HP

  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 m3
  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
    AV-J01040 (40") 1/2 HP     =     333 CMM.
    AV-J01048 (48") 1 HP     =     667 CMM.
    AV-J01048 (48") 2 HP     =     694 CMM.

    The formula for fan (Select models fan to be installed from the top) MODEL: AV-J01048 (1HP) (example)
    The air must transplant out ÷ The ability of the fan required = The number of fans that will be installed.
    22,500.00 ÷ 667.00 = 33.73 ชุด

    *** Calculating may vary depending on operating conditions. Each building has different conditions. ***
    Note : An example of this calculation is the installation of a ventilation fan for Machinery room/ Plant
