CIBSE Western Australia Chapter: Hydronic System Control using Pressure Independent Control Valves


Presentations:

Andrew Crabtree will first draw on his many years of experience in design, commissioning and building tuning to review the underlying principles of flow control and energy optimisation in HVAC systems, balancing the often conflicting components of psychrometrics, fan energy, pump energy and chiller energy inputs. He will also describe the "Trim & Respond" control strategy for static pressure control in VAV systems and differential pressure control in hydronic systems.


Andy Brooks will then describe what Pressure-Independent (PI) control valves are, how they work, how to use them and where to instal them. He will go on to explain the benefits of PI control valves in relation to system control, commissioning procedures and energy efficiency optimisation.


There will be plenty of time for questions and discussion after the 2 presentations and an opportunity for networking and discussion over a drink until the close at 7.00 pm.
