Статья: Разработка и верификация программно-вычислительного метода моделирования температурного режима помещения при аварийных отключениях отопления (2026)

Abstract. Objective. This study presents the development and verification of a computational method for predicting indoor air temperature during emergency heating shutdowns. The aim of the study is to verify the correctness of a digital tool designed to calculate the indoor temperature regime, the rate of air temperature drop and heat losses under intermittent energy supply conditions, taking into account the heat-storage properties of enclosing structures and heating system components. Method. The methodological basis is the theory of thermal stability and the law of regular thermal conditions of the first kind, which describes the cooling process of heating system elements and enclosing structures. The software algorithm consists of two blocks that process the geometric, thermophysical, and operational parameters of the room, external enclosures, and heating system. The software is designed for research and engineering calculations. Result. The developed tool was tested to determine indoor air temperature in both dimensional and nondimensional forms, the rate of temperature drop and heat losses during the room cooling period. Testing confirmed the stability of calculations and their consistency with the physical heat transfer model. Conclusion. The novelty lies in the algorithmic integration of air cooling processes, building envelopes, and the heating system within a single software and computing approach. The method automates calculations of room temperature conditions during heating system outages and is designed to analyze the reliability, energy efficiency, and operational sustainability of buildings.
