HVAC System Control Diagrams – HVAC SCD
HVAC control visualized in a clear and consistent way.
System Control Diagrams (SCD), provide the missing link between HVAC P&ID’s and HVAC PLC software by visualizing control strategies in a clear and consistent way. HVAC SCD’s provide insight in the control strategies and interfaces between systems and they are comprehensible by project participants at various levels and disciplines. The way has been evolved over the last years resulting into a solid standard, NORSOK standard I-005. PDE has been involved in developing HVAC SCD’s for various offshore projects since 2011 and has implemented the way on its onshore industrial projects since 2013. It’s expected that the NORSOK standard I-005 will be transferred into an international standard, such as ISO or IEC, in the forthcoming years.
