Impact of Heating System Local Control on Energy Consumption in Apartment Buildings

Abstract

Improving the energy efficiency of residential buildings is ensured by improving the thermal protection characteristics and the wider introduction of control tools. In order to take into account the influence of individualisation of operating conditions, the study of the regulation of heating distribution of a single-pipe system with bypassed heating devices of a 5-storey typical for Ukraine mass building of the 80s after thermos-modernisation for conditions in Kyiv and Warsaw (Poland) was carried out. On the basis of the simulation model created in the Mathcad software environment for design/rated and average climatic conditions, the influence of internal heat flows into adjacent rooms on the distribution of energy consumption, changes in internal air temperature under the influence of local changes in the heating device flow coefficients were studied. The developed approaches, and the results obtained on the influence of local regulation of devices of vertical single-pipe heating systems can be used to clarify the distribution of energy consumption for heating between individual zones of apartment buildings.
