AI Technical Summary

Technical Problem

In air conditioning equipment with a swing mechanism, the cyclic swing of the swing function causes changes in the static pressure inside the air duct, resulting in unstable constant air volume control, frequent fluctuations in air volume, noise generation, and reduced user comfort.

Method used

By responding to the swing function activation command, the swing mechanism is started and oscillates according to the preset swing cycle. At the same time, the first control cycle is used to control the constant air volume of the fan, so that the first control cycle and the preset swing cycle meet the preset linear relationship, ensuring the stability of the fan speed.

Benefits of technology

During the cyclic swing of the swing mechanism, the stability of the constant air volume control of the fan is maintained, noise is reduced, and user comfort is improved.
