The shell material of the air conditioner is made of thin opal embossed plastic, which is light in weight and elegant in appearance. However, it will occur with the change of temperature and the physical phenomenon of thermal expansion and cold contraction. Therefore, the "split beat" sound of the air conditioner is caused by the small deformation of the shell, not a fault.
