Optimization of Low-Voltage DC Compressor Performance in Solar-Powered Refrigeration Systems for Off-Grid Applications
Abstract
This innovative solar-powered refrigerator, adapted from a conventional AC refrigerator, offers a sustainable and eco-friendly solution for preserving food in off-grid environments. Powered by solar panels, it operates on a low-voltage DC system, ensuring efficient energy utilization. With a 120-liter capacity and R134a refrigerant, the refrigerator can maintain optimal temperatures even during periods of low sunlight. Rigorous testing has demonstrated its ability to reduce chamber temperature by 5.5°C in just 35 minutes, using a modest 12V 7Ah battery. Beyond its environmental benefits, this solar refrigerator offers long-term cost-effectiveness and reliable performance. It is well-suited for a variety of applications, including rural areas, outdoor activities, and off-grid living.
