Calculate cool room capacity in tonnes for fruit, vegetables and meat storage. Plan cold storage requirements for harvest.
Cool room 6m × 4m × 2.5m = 60 m³. Storing apples (0.4 t/m³).
Capacity (tonnes) = Volume (m³) × Loading density. Loading density: Apples 0.35-0.45, Potatoes 0.45-0.55, Meat 0.30-0.40 t/m³.
Total tonnes ÷ loading density = volume. Example: 50 tonnes apples ÷ 0.4 = 125 m³ cold room. Add 20% for pallet space and airflow.
Apples: -1 to 1°C, Potatoes: 2-4°C, Meat: -1 to 2°C, Frozen: -18°C. Humidity 85-95% for most produce.
Cooling capacity (kW) = Volume × 0.1-0.2 for cold rooms, × 0.3-0.5 for freezers. 100m³ needs 10-20kW.
