Design of a Sustainable, Energy-Conserving Portable Refrigeration System

Abstract: In present research work, we have designed a portable refrigeration system that will be ideal for off grid applications in remote areas. The present refrigeration systems are struggling with challenges like more energy consumption, limited reliability and lack in environment sustainability, which have become a major concern in off grid applications. To tackle the same, the proposed design combines innovative, sustainable and energy efficient features like wool wood, duct fans, heat sinks and water circulation pipe grids. Wool wood, a natural material known for its excellent thermal properties. Along duct fans to create pressure difference, heat sinks for heat exchange and a water circulated pipe grid, for better heat transfer properties. These features collectively create a system which is environment friendly and gives better performance in comparison with conventional refrigeration systems. The application of this system include uses in remote and rural communities, emergency medical transport and fieldwork in isolated areas. The system's reliability, performance and the energy saving features have been calculated using computational simulations. The key limitations in a conventional refrigeration system are addressed in this paper, giving more temperature consistency, energy efficiency and with that addressing the growing demand in sustainable technology and off grid scenarios.
