Automotive air conditioning loudly noisy after what car air conditioning is how to return a responsibility, in most cases, after open air conditioning, the sound of the car change is normal. There are a lot of air conditioning, summer about the fault of air conditioning is very much also. Some phenomenon is not a failure. Some novice drivers do not know, may to check the 4 s shop. For example, the voice of the open air conditioning, and regularly check under the engine of the air conditioning dripping water. Automobile air conditioner voice we heard after the big what reason is open air conditioning is the loudest noise in the electronic fan, given out by the high speed of sound insulation good car in the car doesn't sound so clear, when standing outside the car, especially near the front position, can obviously feel the noise is very big. This is very normal, electronic fan high-speed voice is very big, but size models in different noise also is different, some models of noise especially large. There is a noise from the engine, when open the air conditioning, the speed of the engine at idle speed increase, rising about 100 turn around. Because the compressor to start work, the increase of engine load, must raise speed to supplement the power, can appear otherwise seized up, idle instability phenomenon. So in the car listening to, in addition to the electronic fan, motor speed is high, the noise will be larger. Less clear, however, the noise will be covered in electronic fan, electronic fan noise is too big. Why not open air conditioning electronic fan not high speed? Electronic fan operation is for radiator and condenser cooling, it has two gears, low gears and gear, if you don't open air conditioning, it only gives the tank heat dissipation. Low temperature is not open, the water temperature is high, to open, and in most cases, start low gear can have good heat dissipation, don't need to open top gear, low gear noise is small, it doesn't sound clear. If the temperature is high, the vehicle load is bigger, also can open top gear, just a short time stopped, drivers often don't care. And, after open air conditioning condenser always need to have good heat dissipation, or air conditioning refrigeration effect will become worse. So whether high or low temperature, electronic fan to high speed running, the purpose is to ensure that the condenser heat dissipation is good. In addition, after open air conditioning engine load increase, itself also will produce more heat, the temperature will rise, radiator and condenser are need to heat dissipation, so the electronic fan only at high speed, so they have good heat dissipation conditions. If compressor pulley or have a fault, of course, there will be noise increases after open air conditioning, but it belongs to the sound, it is not normal, how can we tell? Have clearly hear two sound louder and electronic fan running a whine, which also will be mixed with other sounds, common is rustling and squeak. The two sound than other sharp voice, it's easy to recognize. That is to say, a single noise, only whine, is normal. Noise is not a single, have two voice mixed together, especially with a sharp, may the voice is not normal, drive to 4 s shops do check in time. After the automobile air conditioning noise is going on, after open air conditioning condenser always need to have good heat dissipation, or air conditioning refrigeration effect will become worse. So whether high or low temperature, electronic fan to high speed running, the purpose is to ensure that the condenser heat dissipation is good. In addition, after open air conditioning engine load increase, itself also will produce more heat, the temperature will rise, radiator and condenser are need to heat dissipation, so the electronic fan only at high speed, so they have good heat dissipation conditions.
