PTC Heater is an automatic constant temperature, power saving heater. It is a heater made of PTC thermistor ceramic elements as heat source, corrugated sheet made of aluminum alloy as radiator, which is bonded and welded.
PTC heater of electric air conditioner generally includes MCU processor, power module MOSFET / IGBT, isolation pre drive and current detection sensor. The control system transmits the temperature to the MCU through the temperature sensor. By comparing with the target temperature input by the key, the MCU continuously adjusts the heater power according to the temperature difference according to the preset program, so that the interior temperature reaches the set temperature level, and the interior temperature and the set temperature are displayed on the LCD screen in real time.
