Abstract

The climatic pecularities of the Russian Federation territory that determine the duration of the heating season are considered. The number of operating heating sources of large, medium and low power is reflected. The equipment wear rate of the heating sources is defined. The emphasis is placed on the need to use shell-and-tube heat exchangers in heating supply systems. The methods to intensify the heating exchange processes in such systems are studied. The research on fluid turbulence changes in a heating circuit of the heat exchangers is introduced, taking into account the different geometry of heat exchangers surface and speed modes. The authors considered the heat transfer surface elements and their location subject to the system construction introduced in Code of Regulations 41-101-95 ®Design of heating units¯
