Web15 jun. 2024 · What is HVAC? HVAC is a term stemmed from ‘Heating, Ventilating, and Air Conditioning’, and it is a system that is aimed to provide comfort for indoor areas. Science contributes to identification of various measures for that comfort and thermal control, and HVAC systems will be engineered based on the desired design points. WebV = 4005 x square root (delta P) Delta P = ( pressure change in inches WC) V = Velocity (ft/min) Determining air flow is a matter of multiplying the cross sectional area of a duct by the air velocity. If the dimensions of the duct are known, then the cross-sectional area can be easily determined and the volumetric flow calculated.
Web3 feb. 2024 · Fans play a major role in an air-handling system and generally HVAC operation. They should deliver the required air volume flow rates at proper pressure to let the air flow pass through different stages with associated pressure drops and then deliver it to the intended indoor area.
