Smart balancing - Part 1 - An introduction to pressure-independent balancing valves

摘要

Attaining proper flow rates through all parallel branches of a hydronic distribution system is a vital part of delivering the expected comfort. The usual intent of balancing is for the installer, or perhaps a separate testing-and-balancing contractor, to adjust several manually set balancing valves so that the flow rates in each branch of the system are at, or very close to, a listing of flow rates prescribed by the system designer. When these design flows are achieved, the system is considered to be properly balanced.
