Abstract

This document defines procedures and methods for the hydraulic optimization of heating, cooling and ventilation systems based on temperature measurements (possibly in combination with other variables/information). It establishes a classification of such temperature-based approaches regarding essential characteristics. This document is applicable to a technically correct dimensioned and constructed hydraulic system from generation to transfer (including piping, heat transfer equipment, storage tanks, valves, pumps, heat exchangers, etc.). This document is also applicable to water-based heating systems, including the heating water side of air heating/air-conditioning systems and to systems that use water without admixtures as a heat transfer medium. This document does not provide a quantitative assessment of the effectiveness of temperature-based optimization approaches - e.g. evaluation of the energy saving potential compared to the hydraulically unregulated state - and no classification of effectiveness in the context of conventional hydraulic balancing on the basis of calculation values.
