A visual representation detailing the components and configuration of a system designed to replace air exhausted from a building. This schematic illustrates the flow of air through various elements, including filters, heating or cooling coils, dampers, and fans, showing their relationships and functions within the overall assembly. For example, a building with significant exhaust systems, like a manufacturing plant or large kitchen, would utilize such a diagram to understand and maintain the system that provides replacement air, ensuring proper ventilation and indoor air quality.
The availability of this visual aid is critical for effective system maintenance, troubleshooting, and optimization. It ensures proper building pressurization, prevents negative pressure issues, and maintains a comfortable and healthy indoor environment. Historically, these diagrams were hand-drawn, but modern computer-aided design (CAD) software allows for more precise and easily updated representations, contributing to increased system efficiency and longevity.
