Introduction

In today's world, where energy efficiency is a top priority, the use of air-air-land exchange devices has become a promising solution. This study focuses on the air-air-land exchange device designed to reduce energy consumption in the air conditioning unit. By using computational fluid dynamics modeling, thermal performance of this tool is analyzed and validated through experimental observation.

The simulation is carried out in transient, incompatible, turbulent, and three-dimensional flow conditions. The heat exchange device used is made of one of the Iron Pipes and PVC with a diameter of 3.0 inches, 2 mm thickness, and a total length of 6.7 m. For testing, the variation in the speed of the fluid flow analyzed is 1 m/s, 2 m/s, and 3 m/s.

Simulation and Experimental Results

The simulation results show that the average air temperature exits at a speed of 1 m/s is 25.45 °C, at 2 m/s is 25.73 °C, and at 3 m/s is 25.84 °C. In comparison, the experimental results recorded the temperature of the exit air of 25.99 °C, 26.33 °C, and 26.01 °C. From these data, there is a deviation between the simulation and experimental results, the highest reaches -3.04% at a speed of 3 m/s and the lowest -10.28% at a speed of 1 m/s.

The deviation between the simulation and experimental results can be attributed to various factors such as the accuracy of the computational fluid dynamics modeling, the precision of the experimental setup, and the limitations of the materials used in the heat exchange device. However, the results still indicate that the heat exchanger system remains optimal in higher speed variations.

Coefficient of Performance (COP)

Furthermore, the analysis of the Coefficient of Performance (COP) value is also carried out. The average COP of the simulation results is 0.703 for speeds of 1 m/s, 0.624 for 2 m/s, and 0.774 for 3 m/s. The experimental results showed 0.6307 for speeds of 1 m/s, 0.5417 for 2 m/s, and 0.7504 for 3 m/s. This data indicates that the performance of the heat exchanger system remains optimal in higher speed variations.

The COP value is a measure of the efficiency of the heat exchanger system, and it is calculated as the ratio of the heat transferred to the heat input. A higher COP value indicates a more efficient heat exchanger system. In this study, the COP value of the simulation results is higher than the experimental results, indicating that the simulation results are more optimistic.

System Effectiveness

The effectiveness of the heat exchange device is also the focus in this research. The average effectiveness of the simulation results obtained 0.956 for a speed of 1 m/s, 0.940 for 2 m/s, and 0.960 for 3 m/s. Meanwhile, the experimental results show a value of 0.8590 for 1 m/s, 0.8164 for 2 m/s, and 0.8970 for 3 m/s. This shows that the heat exchanger has a pretty good efficiency even though there are a few deviations between the simulation and experimental results.

The effectiveness of the heat exchange device is a measure of its ability to transfer heat from one fluid to another. A higher effectiveness value indicates a more efficient heat exchange device. In this study, the effectiveness value of the simulation results is higher than the experimental results, indicating that the simulation results are more optimistic.

From the above analysis, it can be concluded that the heat exchanger of the Irinated Iron Pipe type has great potential in reducing energy consumption, especially in the cooling system. Although there are variations between the simulation and experimental results, the COP value and the effectiveness of the obtained show that this tool can be relied upon. The success of this research opens the way for further development in sustainable energy savings technology. With the application of appropriate technology, the use of this heat exchange device can be one solution to achieve better energy efficiency in the future.
