Abstract

Purpose. Analysis and research of determining critical microclimate conditions in emergency situations in heat supply systems, taking into account external climatic conditions and structural features of buildings, which are caused by the acceleration and cheapening of construction processes thanks to the introduction of the latest technologies. Methodology. Theoretical and experimental research based on fundamental knowledge in the field of thermal processes and methods of solving heat exchange problems, modelling of dynamic processes, methods and analysis of random processes, methods of mathematical statistics and forecasting. Results. On the basis of the conducted research, the regularities of the influence of the environment on the maintenance of the microclimate conditions of the premises, depending on the structural features of buildings and structures in emergency situations in heat supply systems, have been established. The limit conditions for achieving critical conditions of the microclimate of premises as a result of accidents in heat supply systems have been determined, which makes it possible to predict the limit conditions for eliminating the consequences of emergency situations and to optimize the activities of repair and rescue services, which are especially relevant in connection with the failure of outdated heat supply systems and combat operations on territory of the country. Scientific novelty. Determining the patterns of environmental influence on the maintenance of indoor microclimate conditions in connection with the structural features of buildings and structures in emergency situations in heat supply systems, which allows controlling the heat supply mode to ensure certain indoor microclimate conditions. Practical significance. Improving the forecasting of the limit conditions for liquidation of the consequences of emergency situations in heat supply systems allows optimizing the activities of repair and rescue services, especially in connection with the failure of outdated heat supply systems and combat operations on the territory of the country.
