Registration Date 03-02-2025 Organization Institute of Engineering Thermophysics of NAS of Ukraine popup.description1 The purpose of the work is to develop methods and means to ensure energy-efficient heating of premises in crisis, including war, conditions when using electric heating devices of various types. popup.description2 The purpose of the work is theoretical and experimental studies of the thermal regime of a separate room when heated by electric appliances. Research methods are numerical modeling of heat exchange processes and aerodynamics in the room of the building, experimental studies of the thermal regime of a separate room when heated by electric heaters of various types, analysis of the results obtained. During the work, a model was created and numerical studies of the temperature state of the room were performed. As a result, velocity and temperature fields were obtained in the building at different velocities and temperatures of air supply from the heating electric device. From the temperature distribution in the room, it was established that the temperature in the room is distributed unevenly, but the average temperature in the room meets the requirements for the temperature in the room in the winter period of the year in accordance with sanitary standards. Experimental studies of local and operational heat supply modes based on the operation of low-power electric heaters (up to 1.5 kW) were also conducted. Experimental measurements of the temperature and air flow velocity at the distance from the surface of the electrical device were carried out, and measurements of the air temperature in the room at its height were carried out. Based on the conducted theoretical and experimental studies, their feasibility and efficiency are shown and the features of the thermal regime of the room when heated by electrical devices are determined. The use of such heating devices will ensure heating of rooms in crisis and emergency conditions. Product Description popup.authors Bozhko Ihor K. Moroz Maryna V.
