Air conditioning compressor rattling abnormal sound, automobile air conditioning compressor abnormal sound reason
The cause of the abnormal sound of automobile air conditioner compressor
Belt abnormal sound: we know that the air conditioning compressor is generally driven by the engine crankshaft through the belt rotation. And when the belt looseness, aging, wear seriously or the tensioning force of the tensioning wheel is insufficient, it will lead to the belt slipping and running jitter, which will send out the rattling abnormal sound.
Air conditioner compressor damage: The refrigerant in the air conditioner needs to be compressed by the air conditioner compressor, so that the low temperature and low pressure refrigerant is compressed into high temperature and high pressure gas, and then the condenser liquifies and dissipates heat. And when the air conditioning compressor internal damage, will also send a rattling noise.
Air duct foreign body: the cold air blown out by the air conditioner will be transported to the car by the blower after the evaporator cooling, and when there is foreign matter in the air duct of the air conditioner (such as residual branches and withered leaves, etc.), the foreign matter will repeatedly rotate with the air blower and hit the air conditioner filter element, so as to make a rattling noise.
Car air conditioning rattling different sound solution:
When the air conditioning abnormal sound, we should find out the cause of the abnormal sound, and then investigate its root to solve.
Abnormal belt sound: if the abnormal belt sound is caused by the belt, we can directly replace the new belt; If it is due to the insufficient tension of the tensioning wheel, the tensioning wheel needs to be replaced.
Air conditioning compressor damage: in general, when the air conditioning compressor is damaged, whether 4S shop or repair shop only provide replacement repair.
Air duct foreign body: open the air conditioner filter to remove the air conditioner filter element, and then check whether there is foreign body inside the air duct. If there is, clean it directly.
