HVAC system drawings using single lines to represent duct runs are known as what?

Single-line drawings are a simplified way of representing HVAC systems, particularly ductwork, using a single line or symbol to depict the various components and routes within the system. This method emphasizes clarity and efficiency by providing a means to understand the layout and flow of the ductwork without overwhelming details.

In the context of HVAC system design and installation, single-line drawings are particularly useful because they simplify complex systems, making it easier for technicians and engineers to interpret and communicate the design intent. This type of drawing is used in initial design phases, helping stakeholders visualize the system without getting bogged down by intricate details, which are typically included in more comprehensive drawings like detail drawings.

Using single lines allows for a clearer perspective of the entire system layout, aiding in project planning and execution, as it effectively conveys the necessary information with minimal clutter. This helps ensure that all parties involved can quickly grasp the essential components and their relationships within the HVAC system.
