- The purpose of this research to analyze performance of static mobile air conditioning (MAC) system based on compressor speed variation. Refrigerant CFC-12 and HFC-134a used as working fluid. The MAC test rig has several main parts : compressor, condensor, receiver-dryer, thermal expansion valve (TXV), and evaporator. System is equipped with sensors to measure temperature and pressure. Test varied with compressor speed : 1000 rpm, 1200 rpm, 1500 rpm, 1800 rpm, and 2000 rpm. The result indicated that coefficient of performance (COP) decrease with the increase of compressor speed. Ideal and actual COP of CFC-12 is higher than HFC-134a. Refrigerating capacity and power compression of HFC-134a is higher than CFC-12. Keywords : mobile air conditioning, refrigerant, HFC-134a, CFC-12, Coefficient of Performance (COP) vi
