We all know that when the home air cooler works for a long time, the noise of the fan will become louder and louder, but how much do we know about the causes and solutions of the phenomenon? When installing the air cooler, in the choice of location, avoid close contact with other objects. Close installation will cause the fans to collide with each other during operation and generate noise. If it is unavoidable, choose something softer and place it in the middle to fill. When installing the air cooler, lock the wheels of the feet. Do you want to choose a relatively stable ground as far as possible when choosing the place to place the air cooler, so that the wheels of the feet will not collide with the ground, or pad some fillers in the gap to reduce direct ground contact.

The voltage of the air cooler should be controlled within the rated voltage range. When the voltage is too low, the start and operation of the air cooler will produce abnormal noise and vibration. Usually, we can choose a voltage stabilizer or a power regulator. A voltage regulator is used to stabilize the voltage and prevent noise due to low power.
