The Performance of the Adsorption Cycle Cooler that is Driven by Solar Energy with a Collector Area of 1 m2 and a Slope of 30o Collectors

Introduction

Solar energy is the most abundant renewable energy source on earth, and in Indonesia, the potential for use is very large. With an average solar radiation of 4.5 kWh/m² per day in the western region of Indonesia and 5.1 kWh/m² per day in the eastern region, solar energy can be used as the main source for various applications, including in cooling technology. In this study, we will explore the performance of an adsorption cycle cooler that is driven by solar energy with a collector area of 1 m2 and a slope of 30o collectors.

The Adsorption Cycle Cooling Machine

The adsorption cycle cooling machine consists of three main components: collectors/adsorber, condenser, and evaporator. The surface area of the collector/adsorber is 1 m² with a slope of 30 degrees. This collector is filled with 18.5 kg of activated carbon which functions as an adsorption medium, while the evaporator is filled with 5 liters of methanol. In the cooling process, as many as 4 liters of water are used as cooled media.

The adsorption cycle cooling machine works by using solar energy to heat the activated carbon in the collector/adsorber. The heated activated carbon then releases heat to the methanol in the evaporator, causing the methanol to evaporate and cool the water. The cooled water is then used to cool the surrounding environment.

Experimental Results

This research was conducted within a period of three days, which was divided into two periods: the desorption process and the adsorption process. The experimental results show that collectors can absorb solar radiation with a daily average of 7,093,769,356 joules. In the first adsorption cycle, the engine managed to reduce the water temperature to 1.85 degrees Celsius with an average environmental temperature at 26.9 degrees Celsius.

Advantages of the Adsorption Cycle Cooling Machine

The use of solar energy in the adsorption cycle cooling machine has several advantages. First, this technology is environmentally friendly because it uses renewable energy sources that do not produce greenhouse gas emissions. In addition, with increasing cooling needs in various sectors, such as agriculture, industry, and household cooling, the use of this machine can help reduce dependence on fossil fuels.

In terms of efficiency, collectors designed with a slope of 30 degrees are optimal to capture sunlight, especially in tropical regions such as Indonesia. This slope allows collectors to receive direct sunlight at most time a day, thereby increasing the efficiency of collecting solar energy.

Furthermore, the use of activated carbon as an adsorption medium also provides benefits. Active carbon has a very large surface area and high ability to absorb heat, which helps the cooling process become more effective. Meanwhile, the methanol used in the evaporator has a low boiling point, so it can absorb heat quickly to produce the desired cooling effect.

Conclusion

With all these advantages, this cooling machine driven by solar energy can not only reduce operational costs and environmental impacts, but also provides innovative solutions to cooling problems in various sectors. In the future, it is hoped that more research and development will be carried out to optimize this technology and make it more affordable for the wider community.

By understanding and developing this technology, Indonesia can utilize the great potential of solar energy, as well as contribute to global efforts to create a cleaner and sustainable environment.

Recommendations for Future Research

Optimization of Collector Design: Further research is needed to optimize the design of the collector, including the slope and surface area, to improve the efficiency of collecting solar energy.
Development of New Adsorption Media: The use of new adsorption media, such as zeolites or silica gel, may improve the efficiency of the cooling process.
Scalability of the Technology: The technology needs to be scaled up to meet the cooling needs of larger areas, such as cities or industrial complexes.
Cost-Effectiveness: Further research is needed to reduce the cost of the technology, making it more affordable for the wider community.

Conclusion

In conclusion, the adsorption cycle cooling machine driven by solar energy with a collector area of 1 m2 and a slope of 30o collectors is a promising technology for cooling applications. With its environmental benefits, high efficiency, and innovative solutions to cooling problems, this technology has the potential to contribute to a cleaner and sustainable environment. Further research and development are needed to optimize this technology and make it more affordable for the wider community.
