Abstract

The increasing demand for energy-efficient cold storage solutions, particularly in the transport of perishable foods, has led to the exploration of phase change materials (PCMs) as alternatives to conventional refrigeration methods. This study investigates the use of eutectic mixtures of polyethylene glycol (PEG) 600 and PEG 6000 combined with water as PCMs in portable cold storage. The eutectic mixtures were prepared in a 50:50 weight ratio and their performance compared against traditional cold storage using distilled water and no PCM. Key metrics such as storage duration within optimal temperature ranges (-2℃ to 5℃) and temperature homogeneity were evaluated. The results indicate that the PEG 6000 eutectic mixture achieved the best temperature stability, maintaining critical temperatures for up to 4.67 hours, outperforming PEG 600, water, and systems without PCM. However, the temperature uniformity within the storage was suboptimal, with a standard deviation of around 2℃, indicating poor thermal conductivity of the materials.
