1 centrifuge "Tiny Cooling Fan" rotating aerodynamic noise
In fact the biggest factor affecting floor-conditioned indoor noise centrifugal fan is used to rotate aerodynamic noise, such noise is not only concerned with the fan speed but also with the structure of the fan itself relevant. Change the fan speed and the structure can effectively reduce aerodynamic centrifugal fan rotation noise.
Liquid jet noise 2 "Tiny Cooling Fan" capillary
The sound of the refrigerant flow is due to the refrigerant in the refrigeration piping system constantly circulating, pressure, temperature and state of constant noise caused by changes occur. Which is mainly manifested in the refrigerant into the evaporator through a capillary restrictor state jet noise caused by mutations actually entering the evaporator capillary structure is a nozzle, and the nozzle fluid noise is caused by the reflection.
Noise 3 "Tiny Cooling Fan" out of the wind and return air pressure imbalance and the like
Because floor-standing air conditioner indoor unit itself is a send, return air of the closed system, if the structural dimensions of the evaporator is certain, when the return air unhindered when wind output is the largest, and the noise is not the greatest. When the return air hindered, it can drastically reduce the amount of wind, and the noise increased.
