THE COMPLEX APPROACH TO THE MODERNIZATION OF BOILERS, HEAT NETWORKS AND CONNECTED BUILDINGS
The mathematical model that allows for a comparative analysis of the technical and economic characteristics of the three scenarios of the thermal modernization district heating system: the replacement of boilers, heat networks and pumps, the replacement of these elements in combination with thermal modernization of buildings, as well as a scenario that includes the implementation of all previous measures and the installation of Individual Heat Points in buildings (complex modernization). The advantages of the complex modernization on the horizon of planning for 50 years have been shown. Calculated analysis of the influence of various factors on the preference for this scenario has been carried out. The developed model can be used for the preparation of feasibility studies of projects energy efficient modernization of district heating systems and buildings. Bibl. 5, Fig. 8, Tab. 2.
