Abstract

Air conditioning is a widely used technology that conditions an indoor air to a comfortable temperature or a specific temperature adequate to human comfort. The global demand of split type room air conditioning system boosts every year and caused the Earth’s climate worst as a result of global warming due to the emission of fluorine into the atmosphere from the refrigerant that contained in the air conditioning equipment. For split type room air conditioner, new refrigerant (R32) that have lower global warming potential (GWP) have been developed as compensate and to substitute the currently in used refrigerant (R410A) that has higher GWP which deals more damage to the atmosphere. The objectives of this research are to collate operating conditions (energy consumption, temperatures, pressures) and coefficient of performance (COP) of both refrigerant R410A and R32 that operated in both 1hp (horsepower) split type room air conditioners. The experiment research involved two 1hp split type room air conditioners which using different refrigerant (R410A and R32) under the same condition. Validation will be made based on the data collected during the experiment. Instruments such as Digital Thermometer, Manifold Gauges and Power Quality and Energy Analyzer will be used in aiding the data collecting session. The data collected will undergo further analysis by manually using Mollier Chart and software (TechniSolve) in determining the COP of the system. Conclusively, this research is mainly contributes for helping to determine the performance of refrigerant R32 in substituting the currently R410A using in split type room air conditioner.
