The Effect of Adsorber Adsorber Temperature on Refrigerant Absorption in the Adsorption Cycle Cooling Machine

Introduction

The adsorption cycle cooling machine is an environmentally friendly technology that utilizes refrigerant that does not damage the ozone. With a simple design, this machine allows easier maintenance and is an attractive alternative to traditional cooling systems. One important component in this system is the adsorber, which functions to absorb the refrigerant of the evaporator. In this study, an adsorber is used in a flat plate with an area of 0.25 m² and a thickness of 1 mm, filled with 8 kg of activated carbon. This adsorber is heated using a radiation from an electric lamp, and has a collector angle applied is 0 °.

The adsorption cycle cooling machine operates on a unique principle, where the adsorber absorbs heat from the sun during the day, causing refrigerant to flow to the condenser and melt in the evaporator. Conversely, at night, lower environmental temperatures will cool the adsorber, triggering the adsorption process. In this condition, refrigerant that evaporates from the evaporator is absorbed by the adsorber. This study aims to investigate the effect of adsorber temperature on refrigerant absorption in the adsorption cycle cooling machine.

The Importance of Temperature Regulation in the Adsorption Process

The importance of temperature regulation in the adsorption process cannot be ignored. This process is strongly influenced by the temperature of the adsorber adsorber. When the temperature of the adsorber increases, the ability of adsorption to refrigerant such as methanol and ethanol will also increase to a certain extent. In this case, optimal adsorber temperatures not only support the efficiency of refrigerant absorption, but also ensure that the cooling system can operate optimally.

Temperature that is too low can reduce the rate of evaporation of refrigerant in the evaporator, while a temperature that is too high can cause excessive desorption process, thereby reducing the overall efficiency of the system. Therefore, the right adjustment at the adsorber temperature is the key to achieving the optimal performance of the adsorption cycle cooling machine.

Analysis of the Effect of Temperature on Refrigerant Absorption

The study shows that at the thermostat temperature of 200 ° C, the adsorber reaches the optimum temperature to absorb methanol, reaching 123.43 ° C, with absorption of 6.25 ml/kg. As for ethanol, in the same condition, the temperature of the adsorber is 123.16 ° C and the absorption also reaches 6.25 ml/kg. These results indicate that the adsorber temperature has a significant effect on the absorption of refrigerant.

The analysis of the effect of temperature on refrigerant absorption is crucial in understanding the behavior of the adsorption cycle cooling machine. By optimizing the adsorber temperature, the efficiency of refrigerant absorption can be increased, which in turn supports the reduction in the use of hazardous materials for the environment.

Optimal Adsorber Temperature for Refrigerant Absorption

The optimal adsorber temperature for refrigerant absorption is a critical parameter that needs to be optimized. The study shows that the optimal adsorber temperature for methanol and ethanol is around 123.43 ° C and 123.16 ° C, respectively. These temperatures are achieved at a thermostat temperature of 200 ° C.

The optimal adsorber temperature is crucial in achieving the optimal performance of the adsorption cycle cooling machine. By optimizing the adsorber temperature, the efficiency of refrigerant absorption can be increased, which in turn supports the reduction in the use of hazardous materials for the environment.

Conclusion

The adsorption cycle cooling machine is an environmentally friendly innovative solution for cooling needs. By understanding the effect of adsorber's vacuum temperature on refrigerant absorption, we can optimize the performance of this machine. The results showed that the right adsorber temperature can increase the efficiency of refrigerant absorption, which in turn supports the reduction in the use of hazardous materials for the environment.

By continuing to explore and study this technology, we can create a more efficient and sustainable cooling system. The adsorption cycle cooling machine has the potential to revolutionize the way we cool our homes, offices, and industries, and it is essential that we continue to research and develop this technology to make it more efficient and sustainable.

Recommendations for Future Research

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

Investigate the effect of different adsorber materials on refrigerant absorption: The study used activated carbon as the adsorber material, but other materials such as silica gel or zeolites may have different properties that affect refrigerant absorption.

Investigate the effect of different refrigerants on refrigerant absorption: The study used methanol and ethanol as the refrigerants, but other refrigerants such as ammonia or hydrocarbons may have different properties that affect refrigerant absorption.
Develop a more efficient adsorption cycle cooling machine: The study used a simple adsorption cycle cooling machine, but more complex cycles such as a double-effect or a triple-effect cycle may have higher efficiency and be more suitable for large-scale applications.

By addressing these research gaps, we can further improve the efficiency and sustainability of the adsorption cycle cooling machine and make it a more viable alternative to traditional cooling systems.
