Abstract

This study delves into the intricate domain of Peltier refrigeration systems, focusing on the crucial parameter of Coefficient of Performance (COP) as a key metric for system efficiency. Peltier devices, known for their solid-state thermoelectric cooling capabilities, have gained prominence in various applications, including electronics cooling, medical devices, and space exploration. The research encompasses a comprehensive review of existing COP calculation methodologies, considering the unique characteristics and operational principles of Peltier modules. Various factors influencing COP in Pertier refrigeration, such as temperature differentials, electrical input power, and thermal resistances, are analysed in detail. Additionally, the impact of material properties, design considerations, and environmental conditions on COP is explored. Furthermore, the research addresses challenges and opportunities in optimizing COP for Pertier refrigeration, considering the trade-offs between efficiency, cost, and practical implementation. Insights from this study aim to contribute to the ongoing efforts in enhancing the sustainability and effectiveness of Peltier refrigeration technologies across various industries.

Abstract

A cooling machine is an energy conversion machine that is used to transfer heat from a high temperature hot reservoir to a higher temperature hot reservoir by adding work from outside. In clear terms, a cooling machine is equipment used in the process of cooling a material (fluid) so that it reaches the desired temperature and humidity, by absorbing heat from the material (fluid) that will be conditioned, or in other words absorbing heat (heat) from a cold reservoir. and given to the hot reservoir. The method used in this experiment is a quantitative method where we collect data and then process the data to get the Coefficient of Performance (COP) value. the average temperature in the 5th minute was 24.7 ˚C, in the 10th minute it was 22.34 ˚C, in the 15th minute it was 21.66 ˚C, in the 20th minute it was 21.42 ˚C, at the 25th minute it was 21.32 ˚C, and at the 30th minute it was 21.2 ˚C. COPmax data above the 5th minute to the 10th minute there is a temperature decrease of 5.74%, where the temperature decrease is the highest temperature speed decrease compared to other minutes because the series of tools working in the first 5 minutes has a temperature decrease speed of the minute temperature. 5th minute of 24.7 ˚C towards the 10th minute average temperature of 22.34 ˚C. Meanwhile, the decrease in temperature from the 10th minute to the 15th minute was 2.95%. From the 15th minute to the 20th minute temperature, there was a decrease of 2.82%. For the temperature from the 20th minute to the 25th minute, the temperature decreased by 2.77%. Then from the 25th minute to the 30th minute, the temperature decreased by 2.71%. COPactual data calculations also showed a decrease where in the 5th minute it was 0.75%, in the 10th minute 0.33%, in the 15th minute 0.09%, in the 20th minute 0.03%, while in the 25th and 30th minutes the temperature starts constant with a decrease of 0.01%
