Abstract

This work minimizes the issue of traditional Air Conditioners (AC) by employing an innovative design for DC AC and optimizing energy resources, developing an adaptive Feedforward Incremental Conductance (FFINC) algorithm, and conducting experimental validation and cost-benefit analysis. The proposed AC can regulate the moisture levels in a room using an innovative structure that circulates pleasant air indoors. This innovative design represents a potential replacement for traditional AC. The authors have developed a solar air cooler suitable for the modern era that can either replace AC units under specific conditions or reduce their number when operating in hybrid mode. This design sets the distance between the water circulation area and the DC fan at 3 cm to ensure efficient air cooling. The system includes a 60 W DC fan that draws cool air containing water, which passes through a water absorber filter. This filter absorbs excess moisture, resulting in dry, cool air that takes a 90^° circular path to minimize remaining moisture, thereby enhancing air quality. A 20W DC water pump and the DC fan use energy from various electrical sources. Under sunny conditions, a solar panel, connected via a DC to DC zeta converter, provides power to the DC air cooler. During cloudy weather or nighttime, an AC to DC converter is used to optimize operation in emergency situations; a battery is available to ensure uninterrupted operation.
