1st International Conference on Integrity and Lifetime in Extreme Environment (ILEE-2019) Assessment of the emergency recovery ability of heat supply systems in conditions of the Far North Ivanov V.N. a , Ivanova A.V. a , Stepanov A.V., b Kolodeznikova A.N. a, * a North-Eastern Federal University name M.K. Ammosov, Institute of Engeneering & Technology, 50, Kulakovskogo str., Yakutsk, 677000, Russia b V.P. larionov Institute of the Physical-Technical Problems of the North of the Siberian Branch of the RAS, 1, Oktyabr’skaya str,. Yakutsk, 677890, Russia The reliability of heat supply systems depends on the prevention, failure control and improving the efficiency of individual elements of heating systems and heat networks. Standard service life is determined for the operating conditions of central Russia. The heating system and heating networks in the North are engineering according to uniform requirements, as in the middle lane, but they work under more severe conditions due to the extended heating season and low average temperature of the heating period. This paper presents a novel study of the definition of service life and emergency recovery work, considering the factors of geographical location and climatic conditions of operation of elements of heating systems. Performed the analysis of statistical and calculated data for the operation of engineering systems for conditions of the Far North and the Arctic. As a pilot study, heating and heat supply systems are used in Yakutsk, Russia. An analysis of emergency situations of buildings. The results show that the indicator of heat resistance can be used as one of the indicators to select the optimal combination of centralized and decentralized heat supply, taking into account the provision of repair and rehabilitation works. Revealed the dependencies of the period of operational and restoration work on the initial parameters, changes in the temperatures of the internal and external air, the material of the structures and the element of the systems. 1st International Conference on Integrity and Lifetime in Extreme Environment (ILEE-2019) Assessment of the emergency recovery ability of heat supply systems in conditions of the Far North Ivanov V.N. a , Ivanova A.V. a , Stepanov A.V., b Kolodeznikova A.N. a, * a North-Eastern Federal University nam M.K.
