Principle difference between cb 1 nm heating principle: internal metal heating tube, quartz glass wall by nanometer needle plating technology on graphene material and various formulas, quartz glass tube can use conductive and at the same time not conductive properties of quartz glass effectively achieve the separation of water and electricity, have the effect of safety glass surface is very smooth and at the same time solved decades of metal tube (furring this problem, this product is called graphene nano cainuanlu 2 electric heating floor heating principle: hot paste printing on polyester film, the resistance of the conductive paste is equivalent to many parallelly After electrify to fever, the silver metal is equal to the electrode, on both sides of the connection ink resistance, after electrify the electrothermal carbon molecular cluster growing friction between metal and generate heat, heat energy and by far infrared radiation out evenly in flat way, effective electric radiation conversion rate of more than 80%, while heating special materials to ensure a stable long 3 principle of central air conditioning heating heating performance: compressor suction low pressure gas compressed into a high temperature and high pressure gas, through the heat exchanger raised the temperature, high temperature gas will condense into liquid The liquid then enters the evaporator for evaporation. After passing through the evaporator, the liquid turns into low-pressure low-temperature gas. The low-temperature gas is again sucked in by the compressor for compression。
