A refrigerator uses R-12 as the working fluid and operates on an
ideal vapor-compression refrigeration cycle
between 0.15 MPa and 0.8 MPa. The
mass flow rate of the refrigerant is 0.03 kg/s
A) Determine the rate of heat removal (Q˙c) from
the refrigerated space. .
B)Determine the power input to the compressor (W˙net).
C) Determine the rate of heat rejection (Q˙H) to
the environment.
D) Determine the coefficient of
performance (COPR).
E)What-if scenario: What would
the answer in Part B and be if the mass flow rate were doubled?
F) What would the answer in Part C and be if the mass flow
rate were doubled?
