Abstract

This standard considers the balancing of hydronic systems in buildings for the applications of ventilation, heating and cooling. Balancing is understood to mean that, depending on the procedure, water or heat flows are ensured in accordance with the design and calculation. For this purpose, a basic distinction is made between the following procedures: Hydronic balancing Thermal balancing (temperature-based procedure) Hydronic balancing is a procedure for dimensioning and adjusting hydronic systems. In the narrower sense, it means using pipes, fittings and pumps selected for the application, i.e. in accordance with the generally recognized rules of technology, to ensure the determined setpoint water flows by calculating and adjusting regulating resistances or automatically acting balancing elements. In heating and cooling systems, this applies to the areas of generation, distribution and transfer (e.g. room heating surfaces, room cooling surfaces, heat exchangers).
