Background. The urban economy includes a large number of construction sites for various purposes that need reliable and efficient heat supply, and improvement of infrastructure. And at the same time, they must create a safe and comfortable urban environment. The most important state task of rational use of energy resources can be solved using secondary energy resources and renewable energy sources. Therefore, the development of new modern technologies for the secondary use of energy resources in the urban environment is an urgent task. The purpose of the study is to evaluate the energy and economic efficiency of the proposed seasonal heat transformer, designed to maintain road surfaces of various structures during the cold season without ice and snow cover, as well as to produce hot water in hot water supply systems by utilizing the heat of heating the road surface during the warm season.
Materials and methods. The method of balance calculations of heat exchange processes in technological power plants is used in the study.
Results. A device based on heat transformation processes has been proposed to improve the quality of the urban environment. The efficiency of the proposed device and the operating costs of its operation are determined.
Conclusions. The proposed technical solution ensures a reduction in energy costs for buildings and energy savings, and also improves the operational parameters, convenience and safety of the adjacent territories.
