Analysis Of Efficiency Ratio And Coefficient Of Performance (COP) In AC Split Using R-22 Refrigerant

Abstract

Cooling machine technology functions to keep the temperature cool, so this technology is very important for our daily lives, this study aims to analyze the thermal efficiency and Coefficient of Performance in a split AC system using R-22 refrigerant. This study uses an experimental method where system operational data, such as temperature, pressure, and electricity consumption are measured directly at various load conditions. The main parameters analyzed include system thermal efficiency and COP, which show the energy performance of the cooling system. The results of this study indicate that thermal efficiency and COP are influenced by variations in ambient temperature and cooling load. At higher ambient temperatures, system performance tends to decrease, indicated by a decrease in COP and thermal efficiency. These findings provide important insights into the performance of split AC with R22 refrigerant under various operating conditions, which can be used to develop strategies to improve energy efficiency in air conditioning systems.
