The application for the patent was published on June 19, 2026, under issue no. 25/2026.
Abstract: The present invention relates to the design, development and experimental investigation of a solar photovoltaic (PV) powered residential air conditioning system. The system comprises a one-ton inverter split air conditioner operating with R32 refrigerant, four bi-facial photovoltaic panels of 590 W each mounted in a 2x2 configuration, a lithium ferro-phosphate battery storage unit, a charge controller, and a single-phase DC-to-AC inverter. The photovoltaic panels generate 12-15 kWh of electrical energy per day, which powers the air conditioner during sunshine hours and the stored energy in the battery powers the system during off-sunshine hours. The system maintains indoor air temperature at 23 ± 1 °C with coefficient of performance varying between 2.1 and 3.9. The payback period was assessed as 5.5 years. The carbon-dioxide emissions of the proposed system is reduced by about 95 percent compared to the conventional grid-connected coal-based power generation, thereby offering a sustainable and environment-friendly cooling solution for residential applications in tropical climates.
