Air conditioning compressor burned 3 main reasons.
Air-conditioner compressor starts frequently During the start-up process of air-conditioner compressor, there is generally a step-down starting circuit, but the starting current will exceed several times the rated current, and the starting temperature of the air-conditioning compression motor rises very fast. If the temperature of the air conditioner is not set properly, the cooling temperature is too low, and the heating temperature is too high. At this time, the air conditioner compressor is frequently turned on and off, which will shorten the life of the air conditioner compressor.
2, the air conditioning power supply voltage is unstable, the power supply voltage quality is not good, such as the voltage is too high or too low, have adverse effects on the air conditioner compressor motor, especially beyond the rated voltage range of the air conditioner compressor, the most improper, long-term operation makes the air conditioning compressor The motor is in an inefficient overheating condition, resulting in poor insulation and motor winding burnout.
3, air conditioning copper pipe system is not clean enough, which contains water, water can also cause air conditioning compression motor insulation is poor; water and refrigerant and refrigeration oil circulating in the system, high temperature and low temperature state, will produce acidic substances, In turn, the insulation layer of the motor will be destroyed, and the motor of the air conditioner compressor will burn out after a long period of time.
