HVAC - How to Size and Design Ducts - CED Engineering
www.cedengineering.comOrdinary heating, ventilating, and air conditioning duct systems read air pressures at 0.4 psi or less, often much less. 1 psi equals 27.7 inches of water gauge; a common duct pressure of 0.25 inches water column is equal to (0.25 divided by 27.7 in-wc/psi) = 0.009 psi. Duct Pressure: Duct system is pressurized by three pressures: •

www.ct.govDesigning for Wind Pressure This graphic illustrates the effects of wind forces on a building. The arrows indicate positive forces pushing on the surface and negative pressures pulling on the opposing side of the building. The wind forces impact and vary on every surface of the building. In most cases the pulling (-) forces are the higher loads.

CHAPTER 48. NOISE AND VIBRATION CONTROL
tsvibra.irHVAC equipment for a building is one of the major sources of interior noise, and its effect on the acoustical environment is important. Further, noise from equipment located outdoors often propagates to the community. Therefore, mechanical equipment must be selected, and equipment spaces designed, with an emphasis on both
