| Resumen: | The pursuit of sustainable refrigeration solutions has driven significant interest in thermoelectric refrigeration, a technology that operates without the use of environmentally harmful refrigerants. This study aimed to evaluate the technological advancements in thermoelectric refrigeration systems powered by solar energy. A patent search was conducted using the Espacenet database, employing targeted keywords and followed by a manual screening to exclude patents that were not relevant to the topic, resulting in 109 patents meeting the criteria. The findings highlight the potential of Peltier-effect-based refrigeration systems for eco-friendly climate control, despite the low coefficient of performance, and reveal a promising upward trend in patent activity over recent years, especially in 2017 when it reached its peak. The research identified China as the leading country in patent filing and a balance between independent researchers, companies and universities as the leading institutions in patent filing. A comparison of recurring technologies was conducted, and the primary application areas of these technologies were evaluated. Notably, small-scale applications such as vehicle interiors, residences and personal cooling emerged as prominent areas of focus. These findings can guide future investments in eco-friendly refrigeration technologies, contributing to the reduction of environmental impact in the refrigeration sector. |
