ON THE ISSUE OF RESEARCHING CRITICAL CONDITIONS AND OPERATIONAL SAFETY OF HEAT SUPPLY SYSTEMS DURING EMERGENCY HEAT SUPPLY SHUTDOWNS

The issues of ensuring the microclimate conditions of the premises of buildings and structures in the cold season are of exceptional importance, as they are the basis of ensuring the safety of life and people's health. Emergency situations and significant violations of the thermal regime in premises and buildings for an indefinite period of time worsen the conditions of the microclimate, 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 operation of heat supply systems 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 account the spatial location of rooms in buildings and their design features, is an urgent task. The purpose of the article. Theoretical studies of the risk of reaching critical microclimate conditions in emergency situations in heat supply systems, taking into account the spatial arrangement of premises inside buildings and structures and structural features of buildings. Conclusion. Determining the regularities of temperature changes in the premises, reaching the critical temperature and operating time of heat supply systems are necessary for the study of changes in the microclimate parameters of the premises of residential buildings, which are caused by emergency shutdowns of heat supply systems. 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.
