Evaporative cooling — pad and water sizing.
Compute pad face area, indicative water flow and expected ΔT from tunnel-fan cfm and outside conditions.
Inputs
Results
- Pad face area
- 220.2 m²
- Pad efficiency
- 75%
- Inlet air ΔT
- 10.5 °C
- Humidity suitability
- Evaporative cooling viable
- Water flow
- 661 L/min
Design face velocity 1.5 m/s for 6-inch pads.
Saturation efficiency assumption — confirm against the pad manufacturer's data.
Inlet 27.5 °C. Wet-bulb temperature is the physical floor; cooling can never go below it.
Wet-bulb depression 14.0 °C. Confirm against local design-day humidity data, not annual averages.
3 L/min per m² of pad face while pads run.

In short
This cooling calculator is a free browser tool for commercial poultry projects. Enter your own figures and it returns a class-4 planning estimate (about ±30%) under conservative, expected and optimistic scenarios. Use it to size an investment and to brief manufacturers — a firm supplier quote always overrides the estimate.
How to use this calculator
- Enter your project figures. Replace the default values in the cooling calculator with your own flock size, targets and local costs. Defaults are commercial-sector averages, not a recommendation.
- Compare the three scenarios. Switch between conservative, expected and optimistic to see how sensitive the result is to your assumptions before committing capital.
- Read the assumptions. Check the assumptions panel so you know what the model excludes — typically taxes, import duties, special civil works and land.
- Turn the output into a quote request. Send the resulting figures in a single request to receive comparable offers from qualified third-party manufacturers.
