Study of the operation of district heating systems in residential areas

   The article considers methods to improve the modes of operation of district heating systems in residential areas. The authors identify the problem of heat carrier heat supply to the final consumer and describe the main factors that influence the deviation of the design parameters of the heat carrier. The concept and example of the application of the heat supply scheme for residential developments is given. The paper demonstrates methods of regulating the heat carrier and their effect on the operation of the heating network. The authors give schematic diagrams with the peculiarities of each method operation in case of deviation of parameters of supply of quality heat carrier to the final customer. The operation of control valves with different variations of their installation in the heat supply system is shown graphically. It can be concluded that there is a need to revise the provisions of the concept of district heating concerning the regulation of heat loads and the structure of coverage of heat loads of consumers.
