2 kg of Refrigerant-134a contained in a piston-cylinder device undergoes a reversed Carnot cycle.
Some important information about the cycle is:

● At the beginning of the adiabatic compression (State 1), the refrigerant is a saturated vapor.
● The adiabatic compression ends when the temperature of the refrigerant is 30 degrees C
● The refrigerant is 50% vapor by mass at the end of the isothermal heat rejection process.
● The adiabatic expansion process ends when the pressure of the refrigerant is 132.82kPa

Consulting example 7-6 in your text might be helpful in understanding some aspects of this
problem.

a) Represent this cycle on a T-S diagram. On your diagram, clearly indicate the values of the
specific entropy and temperature at every state.
b) Explain (briefly) why the process curves take the shapes you indicated on your T-S diagram
in part a.
