[Abstract]:With the continuous improvement of living standards, people's requirements for indoor living environment are also moving towards a higher level, from the original solution to the basic living problems. To seek comfort and comfort in the living environment, especially as people spend more and more of their life and work time indoors, Indoor heating is the main way for people to resist the cold in winter, but the country is paying more and more attention to energy problems and new energy, traditional centralized heating is facing new challenges. At the same time, a new type of heating system based on carbon fiber strip is presented in this paper, and the design idea, test model and construction process of electric heating plate are introduced in detail. The test results are obtained. The test is divided into three stages: heat conduction heating, simulated temperature control and electric heating system test of carbon fiber strip in fabricated sample house. In the heat conduction heating test, the electric heating plate is formed by burying the carbon fiber tape in cement mortar. In order to obtain the performance of the electrothermal system, the change trend of temperature at different locations and the energy consumption of the system are measured. The results show that the temperature rise of the electrothermal system is rapid. The average heating rate can reach 1.83 擄C / min. The vertical temperature gradient is much larger than the horizontal temperature gradient, the resistance stability of carbon fiber is better, and the thermal insulation effect of ground temperature reflective film and thermal insulation board is good. Under the adjustment of the temperature controller, the electric heating system can reduce the energy consumption significantly. Because of the control and adjustment of the temperature control instrument, the system will automatically enter the rising and cooling cycle stage after a period of pre-heating time at different initial temperature. The effect of initial temperature on the heating rate and the duration of each stage is also consistent. The full-scale study of the carbon fiber strip electric heating plate is carried out, and the electric heating system of the carbon fiber strip in the whole room is investigated. The optimization of carbon fiber strip arrangement has a good result. The lateral temperature difference of each layer of carbon fiber strip electric heating system is small, and the outdoor temperature is relative to the initial temperature. It is a more effective factor to influence the working time and energy consumption in the temperature control phase. The economic applicability of the electric heating system with carbon fiber is compared with that of the three common heating forms in the market. It is found that the carbon fiber strip electric heating system has a broad application range and market prospect in combination with the green residential industrial assembly building which will be strongly advocated by the country in the future.
