Abstract
This research aims to compare the coefficient of performance (COP) of the air conditioning system in a car training kit that uses two different types of condensation, namely using air and water. The research was carried out by implementing these two condensation methods in a car AC system in a training kit designed to simulate real conditions. The data collection method involves measuring the energy consumption and cooling efficiency of both systems. Testing is carried out in various environmental conditions which include variations in temperature, humidity, and other operational conditions that can affect the performance of each system. The research results show a comparison of COP between air conditioning systems that use air and water condensation. The findings show that systems using air condensation have a lower COP, namely 2.24, compared to systems using water condensation with a value of 2.53 in a certain range of conditions. The efficiency of both systems is also influenced by certain environmental factors, but the efficiency value for condensation with air remains lower with a value of 56.92, while with water condensation with a value of 65.10, this gives an indication that condensation using water is better in the air conditioning system in cars. The conclusion of this research is that both condensation methods have their respective advantages and disadvantages in terms of efficiency and performance. The knowledge gained from this research can provide a more in-depth view regarding the application of condensation technology to car air conditioning systems. This can become a basis for further development in improving the efficiency and performance of car AC systems in the future
