Gree air-conditioning semiconductor patent

Of course, auxiliary heating is fast, and electric auxiliary heating refers to PTC electric auxiliary heating technology of air conditioning. In theory, extra electric heating is used to increase the heating capacity, and the effect will be much better. When the electric auxiliary heating is turned on, the air conditioner is heated by both the refrigerant and the electric heating plate, so the heating speed is very fast.

Electric auxiliary heating can automatically change the calorific value according to the change of room temperature and the size of indoor air volume, so as to properly adjust the indoor temperature and achieve the purpose of rapid and powerful heating.

Advantages of electric auxiliary heating

First, the service life is long. Because PTC is a ceramic semiconductor, its structure is relatively stable, which overcomes the weakness of oxidation or deterioration of other electric heating elements due to high temperature or long-term operation, and its service life is beyond the reach of other electric heating elements.

Second, it is safer and more reliable to use. PTC element itself has a strong temperature self-limiting ability, and the highest temperature of the element itself only rises to 70-90℃. Even if the air conditioner fails during operation, it will not cause an accident.

Thirdly, PTC electric auxiliary heating is widely used. The rated voltage of PTC is 220V, but it can work at a normal price when the power supply voltage changes between 100-240V, which is more suitable for areas with unstable voltage.

Fourth, the adjustment is convenient. PTC heating element can quickly reach a stable working state, and the adjustment of heating value is also very convenient.
