Abstract
The study was devoted to solving the issue of creating new electric heating devices that can be used in autonomous heat supply systems. The issues were resolved by developing an original low-pressure electric steam heater. The study was aimed at improving the efficiency of heat supply systems for buildings and structures. Given the current trends in the global striving for energy conservation, it cannot be fully realized without the introduction of high-tech and low-energy-consuming electrical equipment. As a result of theoretical studies of a heat pipe with an electric heater, a design of an electrovacuum heating element has been developed. The low-pressure electric steam heater can be used in heat supply systems of autonomous users. Thermal energy transfer is currently accompanied by substantial energy losses since the heat carrier has to pass considerable distances. Switching of the facility to the heating plant is impossible in some cases because of technical problems or significant material costs for laying pipelines. As a result of the study, the dependence of heating the heat pipe at various volumes of the heat carrier and mass of the pipe itself was established. When a certain mass is reached, the temperature of the heating surfaces can reach 70 °C which is considered acceptable. The experimental data obtained have made it possible to develop an electric heater of new generation with a fundamentally new design of the heating element. It combines the efficiency of an electric spiral and comfortable warmth from a traditional radiator. This heater is an explosion and fire-safe and can be integrated into the Smart Home system
Highlights
Search for energy-efficient solutions in the field of heating residential and industrial premises is an issue of very high topicality
Heating residential and industrial premises with the use of electric heaters is still a rather expensive way to maintain microclimate in cold seasons though this type of heating has a definite prospect of use
Electric heaters are used in many countries as an alternative to central heating since laying and maintaining heat supply lines are quite expensive and their cost can exceed the cost of the project itself with pipelines of large length
Summary
Search for energy-efficient solutions in the field of heating residential and industrial premises is an issue of very high topicality. Conventional centralized heating systems have a number of essential drawbacks, primarily, the necessity of circulation of liquid heat carriers through the pipeline system This is connected with significant operating costs and heat losses in transportation. With the development of the use of renewable energy sources and a decrease in the cost of electricity produced in this way, electric heaters can replace some types of heating systems including centralized ones. Thermal energy must be produced close to the place of its consumption in order to exclude its losses during transportation This is ensured by electric heating systems. LPESH is a new generation electric heater with a fundamentally new energy-saving heating element and an electronic control system It will reduce the costs of heating the premises.
