Engineer's Notebook: Face Velocity Considerations In Air Handler Selection PDF

This month's Engineer's Notebook evaluates methods to reduce fan energy, which accounts for 30% to 40% of building HVAC system energy, from internal pressure drop along with the increased initial costs and reduction in annual operating costs.
