Refrigerant R134a enters the compressor of a refrigerator at 0.14 MPa and -10°C at a rate of 0.12 kg/s and leaves it at 0.7 MPa and 50°C. The refrigerant is cooled in the condenser to 24°C and 0.65 MPa and it is throttled to 0.15 MPa.

Determine:

a. The heat removed from the refrigerated space

b. The power input to the compressor

c. The isentropic efficiency of the compressor and

d. The coefficient of performance of the refrigerator

e. Show the cycle on a T-s diagram
