Animated AHU Cross-Section · Coil Sequencing · Energy Analysis

When to use: Visualize AHU operation with an animated cross-section showing mixed-air dampers, preheat coil, cooling coil, supply fan, and reheat coil. Adjust outdoor air temperature, OA fraction, coil setpoints, and fan speed — watch airflow particles move through the unit and see temperatures update at each section.
