The role of PTC in air conditioning

Posted by sere on March 14th, 2020

Air conditioner PTC ripple heater is a self-controlling temperature heater.

1. Constant temperature heating PTC thermistor has constant temperature heating characteristics. The principle is that the temperature of the PTC thermistor is increased by self-heating after the power is turned on, and the resistance value enters the transition zone. The surface temperature of the constant temperature heating PTC thermistor will remain constant. It is related to the Curie temperature and the applied voltage of the PTC thermistor, but has nothing to do with the ambient temperature.

2. PTC heating element is a heating element designed by using the constant temperature heating characteristics of constant temperature heating PTC thermistor. In the case of small and medium power heating, PTC heating elements have the advantages of constant temperature heating, no open flame, high heat conversion rate, minimal influence from power supply voltage, long natural life and other traditional heating elements. Favored by R & D engineers.

3. The constant temperature heating PTC thermistor can be made into a variety of external structures and different specifications, such as disc shape, rectangle, strip, ring and honeycomb porous. The combination of the PTC heating element and the metal member described above can form various forms of high-power PTC heating elements.
