| 简介 |
The device (FAN COIL UNIT) air conditioner or radiator (RADIAOR) various kinds of wind through an evaporator fan applied so that an electric heater or heating efficiency can be improved as a heating PTC ceramic in heater
More particularly the of the device PTC (Positive Temperature Coefficient Thermally Sensitive Resistor) BaTi03 trace of rare earth oxide element by the addition of Ba imparted thereto, that has conductive portion of the replaced by Pb or Sr capable of moving of re n kind of semiconductor type thin film layers or one or in " on any temperature is reached, temperature by means of transition (Phase Transition) increases with increasing abruptly resistance value is increased is a device having an the properties of. I.e. a feature of the PTC (re) in a constant temperature abruptly increases in resistance value is performed in such a manner that. Thus PCT heating heat dissipating speed heat to prevent a deformation of the generating capability is provided which very quickly, therefore, the operation of the and electrically stable resistivity specific position far infrared in ceramic PTC divergence and is set to more than the temperature of gas is cut off current is excess current and in fires involving and exhibition of highly stable.
Airplane of the device said, publicly known airplane used in heating efficiency using ceramic PTC of the PCT ceramic heater to provide heat exchanger.. |
