Dynamic Thermal Processes in Devices Heated in the Cold

Mathematical experiments on the study of dynamic thermal processes that occur during the heating of technical devices in the cold are considered. The novelty is in obtaining volume representations of thermal processes occurring in these devices over time: their heating at a lower temperature range limit, using previously accumulated thermal energy in a warm room and increasing it due to additional heating by woven electric heaters when the devices are in a warm room. This article may be of interest to developers of heating systems that use autonomous sources of electricity.
