With the improvement of people’s living standards, in areas where there is no central heating, the installation and installation of heating systems – electric heating / plumbing systems, has become the choice of more and more people.
In the past two years, due to the pressure of environmental pollution, the country has implemented a coal-to-electricity heating policy in areas such as Beijing, Tianjin and Hebei. Therefore, electric heating equipment has received great attention.
Compared with the gas furnace, the complexity of the system for producing hot water by air energy machine, as well as the consumption in the early stage, the use of electric direct heating equipment is a convenient installation and an alternative to the whole.
At present, the heating components of electric heating equipment mainly include – carbon fiber, graphite heating sheet, electric resistance wire, graphene-containing heating sheet, which are summed up as two types of heating materials – carbon and wire heating materials, due to the heating of the resistance wire in actual use.It will experience an increase in line loss due to the increase of time. It is used less and less in the application of actual electric floor heating. The current electric heating products mainly use carbon heating materials as heating components.
Carbon fiber, graphite carbon crystal, resistance heating wire, graphene main heating component, carbon heating material, heating mechanism, in the case of energization, carbon molecules generate phonons, ions and electrons, and carbon molecules collide with each other, collision (alsoThermal energy is generated by the Brownian motion. The thermal energy is radiated by the far-infrared method with a wavelength of 5-14 microns. The effective electrothermal energy conversion rate can reach over 90%. For the carbon material with some graphene added, the graphene material is super.Inductive, its heating performance is more stable, the electrothermal conversion efficiency can reach 99%, compared with the traditional carbon material heating, with large unit area power and high energy efficiency, effectively reducing paving area and reducing energy consumption.
Heat Transfer Mechanism of Carbon Heating Materials The reason why carbon heating materials can quickly respond to ceramic tiles is that their 100% power input is effectively converted to convert more than 60% of thermal energy and more than 30% of infrared radiation.
This double heating principle allows the heated object to be gradually regenerated and absorb more heat.
After the power is turned on, the carbon heating material generates a large amount of far infrared rays having an upward wavelength of 5-14 micrometers. After receiving the infrared rays, the ceramic tiles can be absorbed and converted into heat energy to raise the temperature of the ceramic tiles.
Its principle is first-class, “sunshine shines everything.”
Practice has proved that in the environment where the human body feels equally comfortable, far-infrared heating is about 2 °C lower than the ambient temperature required for air convection heating.
Therefore, by using a carbon heating material to heat the interior of the room, the human body feels “hot but not dry”, the whole body is warm and the mind is fresh.
Moreover, far infrared ray assists heating, so that the expectation of heating is significantly reduced.
Infrared radiation heat transfer far-infrared and human body action mechanism 01 From the perspective of theoretical physics, any object above the absolute zero will have radiation, in the ideal case can be simulated with black body radiation, the so-called black body radiation is when it reaches the thermodynamic equilibriumAt the time, its radiation is called blackbody radiation, and the distribution of the governing shot can be expressed by Planck’s law.
The simplified Wien displacement law is the relationship between the front end wavelength itself and the temperature of the black body electromagnetic radiation energy density.
The normal body temperature of the human body is around 37 °C, and the wavelength of the electromagnetic wave wavelength calculated by the law is 9.
About 5 μm.
The object is more likely to absorb energy close to the wavelength of its radiation peak, and far infrared rays in the wavelength range of about 8-14 μm are more easily absorbed by the human body.
02 From the perspective of microscopic energy, molecular vibration and chemical action, when the frequency of the energy wave coincides with the frequency of the molecular vibration, resonance occurs, and the energy is absorbed by the molecule and absorbed by the resonance.
The frequency of the 8-14 μm micron far infrared ray coincides with the vibration frequency of the water molecules, so the energy is completely absorbed by the water molecules.
About 60% of the body’s weight is water, and other macromolecules such as DNA, RNA, and proteins also contain a large number of hydrogen bonds, which can generate resonance energy absorption with far infrared rays.
Water molecules quickly spread to other tissues inside the body after absorbing energy, so when heated by far infrared rays, the human body feels uniform heating from the inside out, without the skin burning sensation of other short-wavelength heat sources.
Far-infrared rays are far less penetrating than high-energy rays such as X-rays, but their energy is effectively absorbed by the human body and is not destructive to other rays.
In the human body, the presence of water molecules is usually surrounded by clusters in the form of clusters or clusters around other macromolecules such as DNA, RNA, proteins and a few. After absorbing energy, the clusters of water molecules are destroyed and the activity of the whole system is increased.The effect is equal to the increase in ionic strength.
Human organs are reservoirs of various biotoxins that cannot be immediately discharged and stored in the body, causing disease.
These toxins are also encapsulated by water clusters and captured in the body.
When these toxins accumulate, blood circulation is interrupted and cellular energy is impaired.
However, when these large water clusters absorb a far infrared wave of 8-14 μm, the water starts to vibrate, destroying the cluster, and the toxin can be quickly eliminated from the body.
Infrared radiation imaging of the human body The effects of far-infrared radiation on the human body’s external and far-infrared radiation can increase the temperature of the skin and subcutaneous tissue, promote blood circulation and metabolism, and promote human health.
The thermal effects of far-infrared ray therapy on tissues, anti-inflammatory effects and promotion of regenerative effects have been clinically affirmed, and usually the treatment uses direct irradiation to the positioning.
Infrared micro-irradiation treatment has a significant effect on the improvement of microcirculation, especially in the micro-blood flow state, which shows that the capillary blood flow velocity is accelerated after the complication, and the red blood cell aggregation phenomenon is reduced, thereby improving the body tissues and important organs.Nutrition, metabolism, repair and function have positive effects.
The far-infrared deep penetration reaches the depths of the muscles and joints, warms the body, relaxes the muscles, drives the oxygen and nutrient exchange of the microvascular network, and eliminates the accumulation of fatigue substances and lactic acid wastes in the body, which is effective in eliminating the internal mass and alleviating the soreness.
Far-infrared rays illuminate the resonance absorption of the human body, which can cause fatigue and aging substances, such as lactic acid, free fatty acids, lipids, excess subcutaneous feces, etc., the activation of the hair follicles and subcutaneous babies, without the kidneys, directly from the skinmetabolism.
Therefore, the skin can be smooth and tender.
The physiotherapy effect of far-infrared rays can improve the heat energy in the body and activate the cells. Therefore, it can promote the metabolism of trace tissues, burn and decompose, consume excess energy, and lose weight more effectively.
Therefore, it is very desirable to decorate the heating tile to warm the floor, especially the electric floor heating product made of graphene carbon heating material. Because it generates far infrared rays during the heating and heating process, it can heat the air and is beneficial to human health.Electric heating products.
