Abstract
Heating, ventilation and air conditioning systems for busses achieve improved air distribution by the use of ducts to distribute the air throughout the passenger compartment. The ducts have a varying cross sectional area so that the impedance to air flow appears constant at all points along the duct. The quantity of air distributed from each of a plurality of vents is substantially even is effectively equalized.
