Question 105
XE-ENAT2 marksNeeds review
A refrigerator operates on an ideal vapor compression cycle between the pressure limits of 140 kPa and 800 kPa. The working fluid is the refrigerant R-134a. The refrigerant enters the compressor as saturated vapor at 140 kPa and exits at 800 kPa and 60 °C. It leaves the condenser as a saturated liquid at 800 kPa. The coefficient of performance (COP) of the refrigerator is ______ (rounded off to two decimal places).
Use the following property data for R-134a:
At 140 kPa:
kJ/kg,
kJ/kgAt 800 kPa:
