Thermal modernization and improvement of engineering systems of campus F of the National University "Yuri Kondratyuk Poltava Polytechnic"

Scientifically based measures for carrying out thermal modernization of a public building, which involve updating microclimate engineering systems by the modern regulatory construction framework, were highlighted in this article. Research is conducted in parallel with the implementation of the "Higher Education of Ukraine" project, which is supported by the European Investment Bank and NEFCO. Implementation of the developed and approved measures for the modernisation of the ventilation, heat supply and heating systems in combination with the insulation of all external envelope structures, according to preliminary calculations, should significantly improve the energy efficiency of the building of the educational building ‘F’. Partial replacement of worn-out heating main pipelines and their complete insulation in accordance with the requirements of DBN B.2.5-67:2013 will reduce heat energy losses for heat transportation, which in turn will reduce heating costs and increase the efficiency of the heating system. Installing an automated individual heat point at the heat network inlet, which consists of a heat meter, a comb, control valves, an electronic controller that controls pumps and control valves depending on indoor and outdoor temperatures, ensures accurate measurement of heat consumption, allows effective adjustment of the operation of the heating system and reduce heating costs. An automatic controller ensures a stable indoor temperature, and the insulation of pipelines helps to avoid additional heat loss. The installation of autonomous ventilation systems with heat recovery in all classrooms and offices that work with CO2 sensors allows for efficient use of electrical energy for ventilation systems, and reduces the cost of heating the supply air through heat recovery.
