Multimodal-fused Dynamic AC Dust Detection for Energy Savings

Abstract This paper aims to achieve an accurate determination of the dust accumulation amount in air conditioners. In the experiment, a scattering-type infrared sensor is used to sense the changes in the optical signal caused by dust accumulation. Combined with the PID control algorithm, dynamic adjustment of the measurement system is realized based on the proportional, integral, and derivative operations of the deviation. Through simulated experimental tests and parameter optimization, this method effectively improves the measurement accuracy and stability, providing a new solution for the monitoring of the dust accumulation amount in air conditioners.
