The inner core of the heating cable is composed of a cold wire hot wire, and the outer layer is composed of an insulating layer, a grounding layer, a shielding layer and an outer sheath. After the heating cable is energized, the hot wire generates heat and operates at a temperature of 40 to 60 ° C and is buried in the filling layer. A heating cable that transmits thermal energy to a heated body by means of heat conduction (convection) and 8-13 um of far-infrared radiation.
The composition and working principle of the heating cable ground radiant heating system:
Power supply line → transformer → low-voltage power distribution device → household electricity meter → temperature controller → heating cable → radiate heat through the floor to the room
a. Using electricity as energy
b. Using a heating cable as a heating element
c. Heat conduction mechanism of heating cable
(1) When the heating cable is energized, it will generate heat. Its temperature is between 40 °C and 60 °C. It is heated by contact, heating the cement layer surrounding it, then passing it to the floor or tile, and then heating the air by convection to conduct heat. It accounts for 50% of the heat generated by the heating cable.
(2) The second part is that the heating cable will generate the most suitable 7-10 micron far infrared rays to the human body and space after being energized. This part of the heat also accounts for 50% of the heat, and the heating efficiency of the heating cable is nearly 100%.
After the heating cable is energized, the hot wire composed of the nickel alloy metal inside is heated, and operates at a low temperature of 40 to 60 ° C, and the heating cable buried in the filling layer passes the heat energy through the heat conduction (convection) manner and the emitted 8-13 μm The far infrared radiation is transmitted to the heated body.
