Prymak A. Autonomous environmentally friendly heat supply systems with seasonal underground accumulators of heat

Subject of inquiry: seasonal underground accumulators of heat. Object of research: development and scientific substantiation of methods of calculating the basic technical parameters of seasonal underground accumulators of heat. Methods of inquiry: theory of heat transfer, computational mathematics, analysis of experiments Theoretical and practical results, innovation: the method of graphing of the thermal load of the systems of heat supply was further developed; there was improved the method of calculations of the basic technical parameters of the storage battery of heat in the water-bearing horizon; the dependence of thermal conductivity, thermal diffusivity and heat capacity of ground on its humidity and porosity is established. Empirical formulas are proposed. Subject and implementation stage: in development plans of Pyriatyn; at the Institute of Renewable Energy of National Academy of Sciences of Ukraine, in Pyriatyn affiliate of the European University, in St. Panteleimonivska Church. Implementation efficiency: there was reduced use of natural gas and other traditional energy sources, reducing of greenhouse gas emissions, potential energy calculations, analysis of mathematical models of heat and mass transfer was carried out. Utilization field: at the enterprises and organizations engaged in the design, construction and operation of heating systems.
