Abstract
In case of emergencies in large heat supply systems, the water temperature in the supply line of the heat supply system is reduced. It is necessary to determine the acceptable duration of the heat supply system during an emergency, taking into account the thermal accumulation of the external fencing and variable water consumption in the hot water supply system. A study was made of the operating modes of the heat supply system in conditions of emergency heat supply from the CHP. The factors affecting the thermal regime of buildings with external fences of various constructions with limited heat supply are considered. A method has been developed for calculating the cooling rate of the inner surface of the outer fence and the temperature on this surface at a given point in time. Calculated dependencies are obtained to determine the acceptable duration of the heat supply system with limited heat supply. Application of the developed methodology can increase energy efficiency and contribute to the energy saving of buildings in the event of emergencies in the heat supply network.
