PROVIDING MICROCLIMATE CONDITIONS, CONSIDERING THE CONSTRUCTION FEATURES OF THE BUILDINGS AND STRUCTURES DURING EMERGENCY SHUTDOWNS OF THE HEAT SUPPLY

Rapid and low-cost construction of modern buildings and structures is provided through the introduction of the latest technologies. At the same time, a significant impact on the modern construction industry of Ukraine is caused by the problem of significantly ageing infrastructure of heat supply systems, which is complicated by the hostilities in the country. This leads to the emergence of critical microclimate conditions. To determine the critical conditions of the microclimate of the premises in case of disturbances in the heat supply system, one of the topical tasks is to investigate the dynamics of indoor air temperature changes in the premises. The purpose of the article. Investigation of the dynamics of indoor air temperature change in order to determine critical microclimate conditions and to provide safe operation of heat supply systems during emergency shutdowns of heat supply systems. Conclusions. 1. On the basis of the conducted research, the dynamics of indoor air temperature changes depending on the construction features of buildings and structures and the influence of external climatic factors (environmental temperature, solar radiation, wind influence) is establish. 2. Based on the conducted modeling of the impact of external climatic factors during emergency shutdowns of heat supply systems the critical time of reaching the boundary conditions of microclimate and maintaining safe operation of heat supply systems are detetmined.
