About this file
The provided file is a detailed ductwork and HVAC system map for the 20th Intelligence Squadron (IS) facility, annotated with technical observations about air handling units (AHUs), exhaust fans (EFs), and air distribution systems. The diagram uses color-coded lines to represent different air flow types: green for supply air, orange for return air, dark blue for outside air, and light blue for exhaust air.
The map highlights several key HVAC system characteristics, including: multiple air handling units (AHU-1 through AHU-5) with varying duct sizes ranging from 8"x10" to 72"x24"; non-functional fan coils; rooms with defunct package units; exhaust fans running continuously; and specific ventilation issues such as bathrooms exhausting into open mechanical areas and rooms with inconsistent return air configurations. The annotations suggest potential maintenance and upgrade needs for the facility's air handling infrastructure.
