Poultry Housing Spreadsheets

1. Tunnel Fan Comparison Spreadsheet 2008

• ↓ Download spreadsheet (50 KB)
• This spreadsheet allows the user to compare different tunnel fans: the number required, air speed produced, and yearly electricity usage.

• Input:

  • house length
  • house width
  • open ceiling/dropped ceiling
  • electricity rate
  • tunnel fan operating hours
  • Air moving capacities of fans you want to compare (@ static pressure of 0.05" - 0.20")
  • Energy efficiency rating of fans you want to compare (@ static pressure of 0.05" & 0.10")
  • You can also input the number of each type of tunnel fan to produce the air speed you desire.

• Outputs:

  • Air speed in the house
  • Number of each type of fan inputted required
  • Air flow ratio of fan inputted
  • Yearly power usage for each of the fans inputted
  • Windchill effect produced
  • 6" pad area required
  • Maximum pad water usage (90 F, 50% Rh and 100 F, 20% Rh)

2. Pullet House Fan/Light Trap Comparison Worksheet

• ↓ Download spreadsheet (73 KB)
• This excel spreadsheet allows the user to determine how  the air moving capacity of their exhaust fans in tunnel ventilated houses will be affected by the addition of different types and sizes of light traps.

• Input:

  • Number of fans
  • Air moving capacity (cfm) of  the fan you want to examine @ static pressures from 0.00" to 0.25" 
  • Type and amount of tunnel inlet light trap
  • Type and amount of tunnel fan light trap

• Output:

  • Total static pressure tunnel fans will be working against
  • Amount of air moved by each tunnel fan.
  • With crossectional area of the house, air moved by each fan, and the number of fans user can calculate the air speed in the tunnel house.
