Excess Heat Management – airflow calculation for excess heat removal

Enter Calculation Data
Heat Load Q (W):
W
Supply / room
Supply Air Temperature °C
Room Temperature °C
Airflow by Δt Value
Formula
V = Q / (ρ × cₚ × ΔT)
Where
  • Q = heat load [W]
  • ρ = air density [kg/m³]
  • V = airflow [m³/s]
  • cₚ = specific heat capacity of air [J/(kg·K)]
  • ΔT = temperature difference [°C] (room − supply air)
Constants
  • ρ = 1,2 kg/m³ (ilma, ~20 °C)
  • cₚ = 1005 J/(kg·K)
Tip: Enter the supply air temperature and the desired room temperature - the temperature difference (ΔT) is calculated automatically from their difference.
