Ventilation Calculation Formulas
Volume = Length × Width × Height
Air Exchange Rate = Volume × Exchanges/Hour (based on crop)
Fan Capacity = Air Exchange Rate / 60 (m³/min)
Vent Area = Floor Area × 20%
Cooling Load = U × Surface Area × ΔT
| Crop Type | Air Changes/Hour |
|---|---|
| Vegetables | 60 |
| Flowers | 45 |
| Seedlings | 30 |
| Tropical Plants | 90 |
