Thermodynamic Properties of HFC-134a Refrigerant (1,1,1,2-tetrafluoroethane) CH2FCF3 molecular Weight 102.3 Bolling point at one atmosphere -26.06C Critical Temperature 374.23K Critical Pressure 4060.3 kPa Critical Density 515.3 kg/m^3 Critical Volume 0.00194 m^3/kg Which is the most effective way to increase the coefficient of performance of a Carnot refrigerator: to increase TC with TH held constant or to decrease TH with TC held constant? Justify mathematically. For a real refrigerator, do either of these strategies make sense?
