Enhancing Energy Efficiency in Air Conditioning Systems via Mechanical-to-Electrical Energy Conversion Using DC Motors

Abstract

This paper explores a novel method for enhancing the energy efficiency of air conditioning (AC) systems by converting the mechanical energy from the external fan into electrical energy using a DC motor. By harnessing this often-wasted rotational energy, the system generates usable power, which can be stored and utilized to reduce overall energy consumption. Our experimental setup demonstrates that at typical wind speeds (5-10 m/s), the system can effectively generate power to charge batteries, contributing to potential energy savings. Additionally, a prototype using a smaller fan validated the concept by generating sufficient voltage for charging lightweight devices, like smartphones. The proposed approach offers a scalable and environmentally friendly solution that could be integrated into existing AC units or new HVAC models, providing significant economic and environmental benefits.
