Fig. 1 Hydraulic balancing of heating and cooling circuits in larger systems requires control valves as well as an option to monitor the actual flow rates.
Changes in thermal and hydraulic conditions affect the hydraulics of heating and cooling distribution systems.
Among the most common causes for an oversupply or undersupply occurring at consumer installations in heating systems, or cooling distribution systems for air-conditioners, is the lack of hydraulic balancing.
For this reason hydraulic balancing of existing systems (Figure 1) is crucial. Furthermore, when modernisation measures have been taken to improve the energy efficiency of a system, a different energy input changes considerably the thermal and hydraulic conditions.
