Are HVAC drawings capable of showing more than one type of control system?

HVAC drawings are indeed capable of showing more than one type of control system, particularly if the project scale allows for it. Larger or more complex projects often implement multiple control systems to manage different areas or types of HVAC equipment efficiently. These controls can include systems such as direct digital control (DDC), pneumatic controls, or even a combination of these, to better accommodate varied environmental needs, energy efficiency goals, and occupant comfort.

The integration of multiple control systems into a single drawing facilitates a comprehensive view of the HVAC system, allowing engineers and contractors to visualize how these systems will interact and function together. This is crucial for coordination among trades and for ensuring that the overall HVAC design meets the requirements of the building while adhering to code and safety standards. Therefore, being able to display various control systems on HVAC drawings is not only possible but often essential in providing a clear understanding of the project's scope and functionality.
