Fabrication of Solar Based Air Cooler and Refrigerator

The increasing global demand for cooling and refrigeration, coupled with rising energy costs and frequent power supply interruptions, has intensified the need for sustainable and energy-efficient alternatives. Conventional cooling systems rely heavily on grid electricity, contributing to high operational costs and environmental impact. In response to these challenges, this project presents the design and development of a solar-powered air conditioning and refrigeration system that utilizes renewable solar energy to provide reliable and efficient cooling solutions. The proposed system is designed to operate flexibly in multiple modes, including air-cooling mode, refrigeration mode, or simultaneous operation of both, depending on user requirements. Solar energy is harnessed, regulated, and stored to ensure continuous operation even during periods of low sunlight or power unavailability. Simple manual control mechanisms are incorporated to allow easy switching between operating modes, making the system user-friendly and suitable for a wide range of applications. Temperature monitoring plays a crucial role in maintaining efficient performance, ensuring optimal cooling while minimizing energy wastage.
