Abstract
In Ukraine, the operation of boiler houses in the unheated period is inefficient. Therefore, it is practiced to shut down boilers at this time in settlements of Ukraine. This makes it necessary for residents to install apartment heaters for hot water supply.The shortcomings of the traditional systems of centralized heating and hot water supply were aggravated in the conditions of intense hostilities and systematic enemy shelling of the infrastructure of populated areas. Moreover, everything is happening against the background of rising prices for energy resources, their shortage and the approach of the heating season.To increase the reliability of the functioning of the energy infrastructure, it is necessary to duplicate centralized sources with autonomous ones, including those based on renewable energy. In order to guarantee the sanitary and epidemiological well-being of the population, together with water supply systems, reliable operation of water drainage systems and heat pumps, which should become sources of low-potential heat in cities, is also necessary.The purpose of the article is to get acquainted with the possibilities of the «TEMPEST» program for the study of the temperature regime of wastewater, as well as the development of a methodology for determining the thermal energy potential of wastewater in sewage collectors.A study based on the «TEMPEST» program for calculating the potential amount of thermal energy in the sewer network was conducted on the example of modeling the temperature regime of the yard sewer network of dormitories No. 7 and No. 8 of the National University of Water and Environmental Engineering (Rivne, Ukraine). The aim of the study was to determine the amount of thermal energy of wastewater that can be recovered for the needs of hot water supply for residents of dormitories with the help of heat pumps.
