AbstractIndesigning air conditioning system, global warming effect within a region isa veryimportant factorbecause itcanaffect theperformanceor the efficiency and theelectricityconsumptionof theair conditioning system. The increase in outsideor environmentwillincrease theheat loadthatmust becontrolled by the air conditioning system. This studyisaimedtoanalyze theincrease of outsideairtemperatureor the environment inthe CityofBandung, West Java, Indonesia on theperformance ofthe air conditioning systemandelectricenergyconsumption. Resultsof this studyindicatethatan increase inoutsideorenvironment air temperaturebyr1oFreducethe cooling power (refrigerating effect) by0.5Btu/lb, in average and increases thetheoreticalcompressorpower by 0.39Btu/lb in average. Theincrease in outside air temperature by 1oF also decreases the Coefficient ofPerformance(CoP)in averageby 0.3; decrease the refrigerantcirculationinthe systemin average by0.025lb/ton-min, andraises electricenergyconsumptionin average by 26.38watts/tonor0.035HP/ton.
