The working principle of the heating cable:
The inner core of the heating cable is composed of cold wire and hot wire, and the exterior is composed of an insulating layer, a to earth, a shielding layer and an outer sheath. After the heating cable is energized, the hot wire generates heat and operating at a temperature between 40-60°C, the heating cable buried in the filling layer transmits thermal energy to the heated body through thermal conduction ( convection) and 8-13um. far infrared radiation.
The composition and working principle of heating cable radiant floor heating system:
Power supply line → transformer → low voltage distribution device → domestic meter → thermostat → heating cable → radiate heat to the room through the floor
p>a. Use electricity as a source of energy
b. Use the heated cablent as a heating element
c. .Heating cable heat conduction mechanism
(1) Heating When the cable is energized, it generates heat between 40℃ and 60℃. By contact conduction, it heats the layer of cement surrounding it. , then transfer it to the floor or tiles, then heat the air by convection. Conductive heat represents 10% of the heat generated by the heating cable
(2). The second part is that after the heating cable is powered on, it will generate 7-10 micron far infrared rays which are most suitable for the human body and radiate towards the human body and space. This part of the heat also accounts for 50% of the generated heat, and the heating efficiency of the heating cable is close to 100%.
The inner core of the heating cable is composed of cold wire and hot wire, and the exterior is composed of insulation layer, grounding, insulation layer. shielding and a gouter groin. Once the heating cable is energized, the hot wire. generates heat and operates at low temperatures of 40 to 60°C. The heating cable buried in the filling layer transfers thermal energy to the heated object through thermal conduction (convection) and 8-13 μm far infrared radiation.
The working principle of carbon crystal floor heating
Under the excitation of electricity, “Brownian motion” is generated by carbon molecular groups, and thermal energy is generated by the collision and friction between carbon molecules generate a large amount of infrared radiation, and its conversion rate of electrical energy and thermal energy reaches more than 98%. Within thirty seconds of power on, the surface temperature of the heating element rises rapidly relative to ambient temperature and transfers thermal energy to the coating on the surface.face of the carbon crystal electric heater and the insulation material on the back of the carbon crystal electric heater. The insulating material continually transfers thermal energy. The coating reflected on the surface of the heating element causes a continuous increase in its surface temperature. After 2-4 minutes, the heating element and the insulating material reach thermal equilibrium and perform thermal radiation. at constant temperature. Its infrared radiation will not produce high frequency radiation. It has no ultraviolet rays or visible light. It is not only harmless to the body, but also can improve the body's microcirculation, promote metabolism, improve human immunity, and is beneficial to health. The wavelength of infrared radiation is between 8 and 18 microns.
