Abstract
The issue of ensuring the microclimate conditions of the premises in the buildings and structures during cold season are of exceptional importance, as it is the basis for ensuring the safety of human life and health. Emergencies and significant violations of the thermal regime in premises and buildings worsen microclimate conditions for an indefinite period of time, until its parameters reach extreme values dangerous for human life. These issues are particularly relevant in the context of the growing number of emergency situations in heat supply systems in Ukraine, both due to the high level of wear and tear of their infrastructure in general, and wartime emergencies. Therefore, conducting research to ensure the safety of heat supply systems operation during emergency shutdowns by determining the regularities of temperature changes in rooms, reaching the critical temperature and operating time of heat supply systems, taking into acount the spatial location of rooms in buildings and their design features, is an urgent task. The purpose of the article. Study of the risk of reaching critical modes of heat supply systems operation in emergency situations, taking into acount the structural features of buildings and ensuring the necessary microclimate conditions. Conclusion. On the basis of the conducted research, the regularities of the structural features of buildings and structures in emergency situations in heat supply systems to ensure microclimate conditions in the premises have been determined. The limit conditions for achieving critical indoor microclimate conditions due to accidents in heat supply systems are determined, which allows predicting the limit conditions for eliminating the consequences of emergency situations and optimizing the activities of repair and rescue services, which is especially important in connection with the failure of outdated heat supply systems and combat operations on the territory of the country.
