These simplified calculations were used to determine the general ventilation level and Over-all ventilation fees for every man or woman within the approximated CO2 era price and measured CO2 equilibrium concentrations. For every man or woman Total ventilation costs have been then calculated using the occupancy.
In spite of a lessen move level, centrifugal lovers develop a steadier movement, leading to a drastically increased static efficiency.
