Static pressure and fan speed
WebOct 23, 2024 · Fan Law 2 tells us that the change in total static pressure of the ventilation system will increase by the square of the change in propeller speed of the fan.If the propeller speed is increased by 10%, the total static pressure will increase 21%. WebFeb 1, 2010 · The building-pressurization-control scheme for the two retro-commissioned buildings is similar to the one employed in many buildings with central-station air-handling systems: Return-fan speed is varied to maintain a set differential between interior-space and outside-air pressure.
