TECHNICAL GUIDE VENTILATING THE ROOMS The air quality in confined spaces (indoor), can cause different unpleasant effects reactions from general malaise to more serious complications on health status. Experts have widely shown that huge concentrations of pollutants like tobacco, smoke, sweat, formaldehyde, carbon monoxide (CO2), radon, etc... can be found in work environments, in public offices, commercial buildings. To improve the quality of air we breath, it is necessary to ventilate the rooms where people live and carry out their several activities. Hence the need to install a fan. HOW...

1) Start with the flow rate value (m3/h) on the right side of the diagram. 2) Proceed horizontally until you cross the diagonal line giving you the diameter of the duct you need. 3) Descend vertically to find the value of the pressure loss expressed in mm H2O per each meter of duct. Multiply this value with the required lenght of pipe and you will find the total pressure loss value. If you want the value in Pa, multiply the value by 9,81. 4) At the intersection of the flow rate and duct diameter values, follow this line upwards until it intersects with the recommended air speed (m/sec)....
