System equipment, such as chillers and individual terminal units, is the heart of any HVAC system. Extreme care and time is dedicated to their selection and performance criteria. However, without proper flow through these units, their efficiencies and heating or cooling transfer capabilities are altered.
By specifying automatic balancing, the designer is assured that the system is accurately and dynamically balanced. This means that all components will perform as specified regardless of changes. With automatic flow regulators, the terminal units will not exceed design flow even after modifications or additions to the system.
In a proportionally (manually) balanced system, such changes can cause overflow unless adjustments are made at risers, branches, and terminal.
Automatic balancing offers a number of other benefits such as: pump energy savings, lower head requirements and less balancing labour. For more information on autoflow and the other products, please refer to FDI's webpage.
