| Summary: | Simulation models are used by engineers in designing buildings climate systems. Such models are essential for solving a problem of improving energy efficiency of capital construction objects. The model can be applied as a tool for investigating building and constructions energy (energy modelling) when developing the techno-economic justification in the energy management system according with ISO 50001:2011 "Energy management systems - Requirements with guidance for use". Solar radiation is one of the major factors affecting the thermal regime of the building. Implementation of the intelligent control system of heat consumption allows increasing energy efficiency in case of maintaining optimal climatic parameters in rooms. The main aim of the study is to develop the integrated model of building and weather conditions simulation block for carrying out subsequent studies of the solar radiation influence on thermal processes inside the building, as well as for evaluating energy saving potential. The methods used in the study: simulation using the software package Simulink and special libraries Simscape of "acausal" modeling. The results. The authors have developed the integrated model of building and investigated the insolation processes typical for climatic parameters of Western Siberia (February). The paper introduces the research results of the indoor air temperature dynamics in the control rooms. The received data on changing the thermal regime of the control room allowed further studying of heat exchange with the environment, as well as determining the effect of solar radiation on heat supply control system functioning. The paper introduces the conclusions on the efficiency of the disturbing factor compensation for achieving energy saving effect. |
