Method.
Background technology
Heating System of Electric radiant Heating Film is different from using radiator, air-conditioning, radiator as the point heating system of representative and with hair
Electric heating cable is the wire type heating system of representative, the low-carbon heating high-tech that formula heating field is researched and developed using modern aerospace flight technology in face
Product.
Electric heating heating film principle is product under the action of electric field, and the carbon molecules group in heater generates " Brownian movement ",
Violent friction and shock occur between carbon molecules, the thermal energy of generation is externally transmitted in the form of far infrared radiation and convection current,
The conversion ratio of electric energy and thermal energy is up to 98% or more.The effect of carbon molecules makes system surfaces be brought rapidly up.Electric radiant Heating Film is warmed up into heating
System be mounted on wall () on face, thermal energy will continuously be evenly transferred to each corner in room.The institute of Electric radiant Heating Film
That can play the role of being brought rapidly up to space, in that its 100% electric energy input be efficiently converted to be more than
66% far infrared radiation energy and 33% convection current thermal energy.Policy guidance of the Electric radiant Heating Film because meeting emission reduction low-carbon, development prospect
It is wide.
Existing Electric radiant Heating Film is thin through printing, the hot pressing polyester that insulate at two layers by conductive special ink, metal current-carrying item
Manufactured a kind of special heating product between film, the product is by power supply, temperature controller, connector, insulating layer, Electric radiant Heating Film and finish coat
It constitutes.Using Electric radiant Heating Film as heater when work, heat is sent into space in the form of radiation, body is made one and basks, is integrated
Effect is better than traditional heating system.
