This model assumes co2 as an ideal gas to calculate the density of co2:
rho_CO2 = p_Air * w_CO2 * M_Air / (R * T_Air)
The delivered volume flow rate results to:
V̇_CO2 = RQ * M * A_Body / CE * T_Air/ 273.15 K
The zone is assumed to be occupied by men to determine the amount of CO2 emitted. For a different occupancy the default values must be replaced.
