Low temperature electric heating film is a semi transparent polyester film that can generate heat after being electrified. It is made of conductive special ink and metal current carrying strips processed and hot pressed between insulating polyester films. When working, an electric heating film is used as the heating element, which sends heat into the space in the form of radiation, making the human body and objects warm first. Its comprehensive effect is superior to traditional convective heating methods. The low-temperature radiation electric heating film system is composed of a power supply, a temperature controller, connectors, an insulation layer, an electric heating film, and a decorative layer. The power supply is connected to the electric heating film through wires, converting electrical energy into thermal energy. Due to the pure resistance circuit of the electric heating film, its conversion efficiency is high. Except for a small loss (2%), the vast majority (98%) is converted into heat energy. Electric heating film cannot be directly used for ground radiation heating, and a patented PVC vacuum envelope needs to be added to ensure its effectiveness and lifespan in ground heating. The development potential of electric heating film is enormous, which is in line with the trend of low-carbon economic development. The electric film heating method does not consume water, does not occupy land, has independent switching, is energy-saving and material saving, and conforms to the policy direction of emission reduction and low-carbon, with broad development prospects
