Consider a 5 kW refrigeration system that operates on an ideal vapor-compression cycle with R-134a as the working fluid. The refrigerant enters the compressor as a saturated vapor at 200.74 kPa and is compressed to 1.2 MPa. (a) Sketch the Temperature (T) against Entropy (S) diagram for the ideal vapor- compression cycle. Indicate clearly the components involved and the work and heat contributions/losses. [7 Marks] (b) Use relevant property table to determine the temperature of the refrigerant entering the compressor (c) Determine the specific entropy s of the refrigerant exiting the compressor (d) Determine the temperature of the refrigerant exiting the compressor [2 marks] [3 marks] [5 marks] Consider a 5 kW refrigeration system that operates on an ideal vapor-compression cycle with R-134a as the working fluid.
