Description
While an architectural drawing might specify the size of a wall opening, the actual space available for air to enter a building is significantly smaller. Specifying the right louver requires more than just picking a design; it requires a precise understanding of how the physical geometry of the louver interacts with mechanical airflow.
Louvers 103: Louver Performance explores the critical relationship between a louver's physical construction and its aerodynamic efficiency. This highly interactive module guides learners through the core mathematical calculations that drive the air movement industry. You will explore how to calculate unobstructed openings, predict airflow resistance, and navigate the complex trade-offs required to balance high-volume ventilation with maximum weather protection.

Objectives
-
Define key airflow terminology, including Free Area, Free Area Velocity, and Pressure Drop.
-
Calculate the Free Area Velocity of a louver when given the total system airflow (CFM) and the louver's Free Area.
-
Explain the exponential relationship between air volume (CFM) and resistance (Pressure Drop) within a mechanical system.
-
Calculate the increased pressure drop penalty introduced by louver accessories, such as bird and insect screens.
-
Analyze the engineering trade-offs required to balance high Free Area (ventilation) with effective blade geometry for water rejection.
