Features of heat exchange in office premises with radiant cooling

Decarbonization of the engineering systems of buildings and structures is extremely important both for achieving zero emissions of greenhouse gases and for ensuring energy security of countries. One of the main consumers of energy in public buildings, in particular in office premises, are cooling systems, which maintain the temperature of the internal air in the premises during warm periods of the year. To achieve the goals of energy saving and high thermal comfort in the premises, it is advisable to use radiation cooling systems. Modeling methods are used to describe the behavior of radiation cooling systems and to assess the influence on them of various factors. In this article, modeling of thermal interactions in an office premises is performed using graph theory. As a result of mathematical modeling, heat balances for the heat capacities of the room were drawn up and systems of balanced equations were proposed. In addition, the article provides a graphic dependence of the area of the ceiling cooling panel on the temperature of the internal air and heat gain from solar radiation in the office premises.
