Abstract. This work addresses the limitations of traditional air conditioners (AC) by incorporating an innovative design for DC air conditioners, optimizing energy resources, developing an adaptive feedforward incremental conductance (FFINC) algorithm, and validating the approach through experiments and a cost-benefit analysis. The proposed AC is designed to effectively regulate moisture levels within a room, utilizing an innovative structure that circulates comfortable air throughout the room. This design serves as a promising alternative to traditional air conditioning systems. 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. Proposed design maintains a distance of 3 cm between the water circulation area and the DC fan to optimize air cooling efficiency. The system includes a 60 W DC fan that draws cool air containing water, which passes through a water absorber filter. Moreover, a 50 W dehumidifier inside the air cooler effectively controls room humidity, ensuring that the air remains dry and comfortable. By absorbing excess moisture, the dehumidifier enhances the overall cooling performance of the system, contributing to improved air quality and comfort for occupants. A 20 W 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.
