Abstract
The need for sustainable and off-grid refrigeration systems is critical in rural and remote areas where electricity supply is unreliable. This study explores the design, construction, and performance analysis of a novel refrigeration system using Liquefied Petroleum Gas (LPG) as a refrigerant. The system utilizes the expansion of high-pressure LPG through a capillary tube into an evaporator to achieve cooling, eliminating the need for mechanical compressors or electrical energy. Experimental trials showed a consistent temperature drop from 33C to 27.9C in 12 minutes with minimal pressure fluctuation, validating the concept. The paper presents a cost-effective, environmentally friendly, and efficient refrigeration solution for underserved communities.
