ДОСЛІДЖЕННЯ ТЕПЛОВИХ ХАРАКТЕРИСТИК ЕЛЕКТРИЧНИХ ОПАЛЮВАЛЬНИХ ПРИЛАДІВ
In recent years, there has been a trend of transition from gas to electric heating, due to changes in the energy sector of the economy. Mass use of portable electric heaters allows to reduce fuel consumption by 25%, significantly reduce heat loss and negative impact on the environment. Electric heat...

| description |
In recent years, there has been a trend of transition from gas to electric heating, due to changes in the energy sector of the economy. Mass use of portable electric heaters allows to reduce fuel consumption by 25%, significantly reduce heat loss and negative impact on the environment. Electric heating is characterized by affordability, high efficiency, low costs of installation and maintenance, the ability to use preferential tariffs.
The purpose of the article is to analyze the technical and economic characteristics and efficiency of typical household electric heaters. The article contains an experimental study of the heat flux and heat of radiation of selected structures. The heat flux density was determined by the calculation method and in comparison with experimental data. Complex heat transfer is taken into account by calculating the heat transfer coefficient. Numerical and experimental study of the natural flow of convection in combination with radiation is carried out with each heated device in the laboratory.
A comparative analysis of the ratio of thermal characteristics to the cost and efficiency of devices. With the help of the author's method of "centers of mass" the comparison of qualitative characteristics of devices is carried out. As a result of the analysis it was established that the ALMAZ TERM Panel does not meet the set quality conditions, which requires further refinement of the design and technological indicators.
Studies show that it is possible to increase the efficiency of heating devices by increasing the consistency of the temperature profile, changing the radiation factor, optimizing the heat transfer surface of the device, as well as by integrating heat storages to store and improve heat distribution. In this case, the electrical energy is converted into heat and stored with subsequent use during peak hours. |
