Peculiarities of thermomodernization of the heating system of military infrastructure complexes

Abstract

Purpose. To develop a solution for modernization of heat supply systems (HSS) of infrastructure complexes including, in particular, in military towns (MT), the problem of both efficient and effective heating of which is especially important at present. To develop a mathematical model for finding an effective solution to the problem of modernizing heating and detecting leaks of the heat-conductor. Methodology. Special and general methods are used: mathematical formalization – to build mathematical model of the problem of heat supply of MT and detection of heat-conductor leaks; induction and deduction – for choosing and substantiating the expediency of using equipment for HSS of MT; analysis and synthesis – for the development of a schematic solution HSS of MT. Findings. Decision options regarding the choice of heat-generating equipment for the modernization of HSS of MT are substantiated. A combined system using boilers and solar collectors is proposed. For the combined system, a schematic solution for integrating equipment into a single autonomous HSS of MT and an economical option for automatic system control are developed. For boilers of the combined system, it is suggested to use cheap and affordable fuel – pellets. A mathematical model has been developed for finding an effective system solution for HSS of MT and detecting heat-conductor leaks. Originality. Special requirements for HSS of MT were formulated: autonomy; high level of reliability, survivability; flexibility in ensuring the volume of heat supply during the day, week, season; minimizing the cost of equipment and fuel for it; the possibility of inexpensive repair and renewal. Variants of modernization of HSS in MT have been analyzed and a schematic solution of an integrated HSS of MT with combined use of generating equipment has been developed. Practical value. The developed mathematical model and schematic solution of HSS in MT as well as proposed options for using equipment and fuel for it allow ensuring the proper level of fulfillment of special requirements for HSS in MT.
