HVAC Ducting Principles and Fundamentals
pdhonline.com3. High Velocity Duct Systems: High-velocity (HV) duct systems are characterized by air velocities in the range of 2500 to 3500 fpm. Low-velocity ductwork design is very important for energy efficiency in air distribution systems. Low-velocity design will lead to larger duct sizes, but it may be worth since, doubling of duct diameter
