Solar Based Air Cooler Using BLDC Motor

Abstract - With the intensifying global demand for thermal comfort, traditional cooling systems are contributing significantly to high electricity consumption and environmental strain. This research proposes an innovative solution by developing an evaporative air cooler powered by solar photovoltaic (PV) energy and driven by a Brushless Direct Current (BLDC) motor. Unlike standard coolers that use AC induction motors, the integration of BLDC technology offers superior efficiency, reduced thermal loss, and enhanced longevity. The system utilizes a dedicated charge controller to manage energy harvested from solar panels, storing it in a battery unit for consistent operation during non-sunny periods. Experimental observations indicate that this system provides a cost-effective and sustainable cooling alternative, particularly effective for off-grid applications or regions facing frequent power instability.
