Design of Solar Refrigerator with a Cooling Capacity of 10 Liters of Water

Introduction

Refrigeration is a crucial process in various industries, including food and beverage, healthcare, and pharmaceuticals. It involves cooling an object to reach lower temperatures than environmental temperatures. In this study, a refrigeration system based on a steam compression-based system has been designed that utilizes solar energy as a power source for running a cooling machine. Considering that Indonesia has a great solar energy potential, this system is very suitable to be applied, especially as an alternative solution for areas that have not been reached by equitable electricity supply.

Background and Significance

The use of solar energy in refrigeration systems is not only environmentally friendly but also provides high energy efficiency, especially in tropical countries like Indonesia. The use of natural resources helps reduce dependence on conventional electricity which is often uneven, especially in remote areas. In the context of fisheries, fishermen benefit greatly from this technology, because they can store better catch results, reduce decay, and improve the quality of products sold.

Design and Construction of the Solar Refrigerator

The author has designed and built a solar cooler with a capacity to cool 10 liters of water. The size of the cooling box designed is 25 cm x 20 cm x 20 cm with a wall thickness of 7 cm. This system is able to produce a cooling load of 1313.3 W, with the solar panel area used is 3.04 m² and has a power of 25 WP. The design of this solar refrigerator is very beneficial for fishermen who are going to sea, because they need an efficient cooling system to maintain the freshness of fish catches.

Additional Analysis and Explanation

The cooling load of 1313.3 W produced by this system shows that this cooling machine is able to work effectively under certain conditions. In practice, this means the refrigerator can cool more than just water, allowing the storage of various types of food and drinks. With a solar panel that has a power of 25 WP and an area of 3.04 m², this shows that the efficiency of the panel is very good in producing the energy needed to operate.

Applications and Potential

This solar refrigerator is a very relevant choice to be applied in coastal areas, where electricity access is often limited. With this tool, fishermen can have a practical and ongoing solution to maintain the freshness of their catch while in the sea. In addition, this technology also has the potential to be applied to other sectors, such as animal husbandry and agriculture, where storing products efficiently becomes crucial.

Conclusion

Overall, the design of the solar refrigerator is not only a technology innovation, but also reflects how the appropriate approach in utilizing natural resources can have a positive impact on the community, especially in supporting the welfare and economic sustainability in areas that are less served by conventional electrical infrastructure.

Future Directions and Recommendations

The use of solar energy in refrigeration systems has a great potential to be applied in various industries and sectors. However, there are still some challenges that need to be addressed, such as the high initial cost of the system and the limited availability of solar panels in some areas. Therefore, it is recommended that further research and development be conducted to improve the efficiency and affordability of the system.

Limitations and Challenges

One of the limitations of this study is that it only focuses on the design and construction of the solar refrigerator, without considering the economic and social impacts of the technology. Therefore, further research is needed to investigate the economic and social benefits of the technology and to identify the potential challenges and limitations of its implementation.

Recommendations for Future Research

Based on the findings of this study, the following recommendations are made for future research:

Investigate the economic and social impacts of the solar refrigerator technology
Develop a more efficient and affordable solar panel system
Conduct a feasibility study to identify the potential applications and challenges of the technology in various industries and sectors
Develop a business model to support the commercialization of the technology

Conclusion

In conclusion, the design of the solar refrigerator with a cooling capacity of 10 liters of water is a significant innovation that has the potential to improve the efficiency and sustainability of refrigeration systems in various industries and sectors. However, further research and development are needed to improve the efficiency and affordability of the system and to address the potential challenges and limitations of its implementation.
