Balancing fittings in a water heating system

Abstract

Energy conservation and improving energy efficiency are priority areas for the development of the global economy. The need to increase the energy efficiency of the engineering equipment of buildings is due to both the requirements to reduce the energy consumption of buildings in general, and the increase in the proportion of energy-consuming climate systems used in modern construction. In large modern office, hotel and residential complexes to achieve the greatest energy efficiency it is necessary to use various technical solutions. The main element of an energy-efficient heating system is regulation. Balancing devices allow to not only balance and tune the system at any time of operational period but also serve as stop valves during reparation and diagnostics. Determination of energy savings bases on the average value heat consumption before and after modernization, depending on the type of installed valves or their combination. The focus of the work is hydraulic calculation of the heating system the authors conduct research on the effect of differently balancing fittings on the hydraulics of the heating system.
