WebQ2. Consider a 300 kJ/min refrigeration system that operates on an ideal vapor-compression refrigeration cycle with refrigerant-134a as the working fluid. The refrigerant enters the compressor as saturated vapor at 140 kPa and is compressed to 800 kPa. Show the cycle on a T-s diagram with respect to saturation lines and determine (a) the ... WebA refrigerator using refrigerant-134a as the working fluid operates the condenser at 700 kPa and the evaporator at -10°C. This refrigerator freezes water while rejecting heat to the ambient air at 22°C. The compressor has an isentropic efficiency of 85 percent. Determine the process that causes the greatest amount of exergy destruction if ...
Webcalculation of constants for HFC-134a were performed for Du Pont at the National Institute of Standards and Tech-nology (NIST) under the supervision of Dr. Mark O. McLinden. The constants were calculated in SI units. For conversion of thermodynamic properties to Engineering (I/P) units, properties must be calculated in SI units and converted to ...
