This study addresses the challenge of developing energy-efficient cooling solutions for arid climates through the experimentation of a solar photovoltaic (PV) powered thermoelectric cooler (TEC), known as a photo thermoelectric air conditioning (PTE-AC) system. The research aims to offer a sustainable alternative to traditional air conditioning systems, particularly in hot, arid regions like Dhahran, Saudi Arabia. The methodology involves fabricating and evaluating the PTE-AC system, which operates exclusively on solar PV power to create distinct hot and cold chambers for personalized cooling. Experimental results reveal that the PTE-AC system reaches its peak performance at an electrical input of 6 A and 5V, achieving a maximum coefficient of performance (COP) of 0.498 and a cooling capacity of 54.8 W. The system's ability to produce condensate varied, with average outputs of 11.7 g/h, 13.8 g/h, and 16.4 g/h recorded under power settings of 4 A, 5 A, and 6 A respectively. In operational conditions, the system maintained an ambient temperature range around the occupants between 22.1 °C and 29.2 °C, with an average of 24.5 °C, at the optimal input setting of 6 A and 5 V. The research contributes significantly to the field by presenting a Freon-free, low-carbon dioxide, and energy-efficient cooling solution, demonstrating a practical application of solar-powered thermoelectric technology in building engineering. The novelty of this study lies in the approach to leveraging solar energy for efficient personal cooling, offering a viable and sustainable alternative to conventional air conditioning in arid climates.
