On the influence of local and zonal hydraulic balancing of heating system on energy savings in existing buildings - Long term experimental research

摘要

The application of regulation valves in new and existing buildings allows for proper hydraulic balance of the heating system and in this way it may increase the energy efficiency of heating installation. Unfortunately, to the best of authors' knowledge, there are no long-term field studies that present the level of energy savings achieved by means of commonly used valves in engineering practice, such as thermostatic radiator valves (TRVs), under risers differential pressure control valves (DPCVs), pressure independent balancing radiator valves (PIBRVs), as well as a combination of them.
