Tunnel Fan Comparison Spreadsheet 2014
- This spreadsheet allows the user to compare different tunnel fans: the number required, air speed produced, and yearly electricity usage.
Input:
- House length
- House witdh
- open ceiling/dropped ceiling
- Minimum desired tunnel fan capacity (typically between 9 and 11 cfm/ft2)
- Electricity rate
- Estimated 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")
- Desired air speed
Outputs:
- Air speed in the house
- Number of each type of fan inputted required
- Air flow ratio of fan inputted
- Estimated air moving capacity of each tunnel fan at expected operating static pressure
- Total air moving capacity of the tunnel fas at expected operating static pressure
- Yearly power usage for each of the fans inputted
- Theoretical windchill effect produced
- Number of tunnel fans required are based of the expectant static pressure at the desired air speed
- 500 ft/min = 0.10"
- 600 ft/min = 0.15"
- Over 725 ft/min = 0.20.
- 5 and 10 year operating costs
