In electricity, it is able to reach the normal temperature in the initial half an hour. The heating power is 220W, reaching the set temperature, if 100 square meters of heating area (construction area of about 130 ~ 150 square metre) count laying 59 square meters of electrothermal membrane computing, 220V voltage normal usage rate according to: 102W (using the thermal insulation material case) initial full load power 220W.
The operating power P=UI, depending on the voltage and resistance of the equipment. The resistance value of the electrothermal membrane can be measured with an ohmmeter from the end of the thermostat. Generally speaking, the actual resistance is with a little diffrence with the square power and product of area. Therefore, after the acual pavement of the electric heating film has been done, the construction staff will give the actual pavement power. Due to the fluctuation of voltage during the operation of the equipment, it will also cause changes in the power of the electric heating film, if the voltage is low, the power will be small, the heating time will be extended.
To measure the DC resistance and square the rated voltage divided by the DC resistance, then the power is calculated. The electric heating film is divided into high temperature and low temperature electric heating film. The high temperature electric heating film is generally used in electronic, military and so on. The electrothermal?film produced by the Today Technology. The low temperature electric film is a semitransparent polyester film after it is powered. It is made of by the special conductive ink. It is processed by the metal carrier and made between the insulating polyester film. When working, it takes the electrothermal?film as the heating element and sends heat into the space in the form of radiation. It can first make people's body and the objects to get the heat. It's integrated effect is far better than the traditional method of convection heating. The low-temperature radiant electric heating film system is composed of a power supply, a temperature controller, a connecting piece, an insulating layer, an electric heating film and a facing layer. The power supply is connected with an electric heating film through a conducting wire, and the electric energy is converted into heat energy. Because the electric heating film is a pure resistance circuit, the conversion efficiency is high, in addition to a small partial loss (2%), the vast majority (98%) is converted into heat energy. The electrothermal membrane can not be directly for the radiant floor heating, requiring additional patent PVC vacuum envelope, it can be used in floor heating to ensure the use of effects and life. The development potential of electric heating film is huge, which is consistent with the trend of low carbon economy development.
