(Figure 1), uses R-134a as the working fluid and operates on an
ideal vapor-compression cycle. The temperatures in the condenser,
refrigerator, and freezer are 25 ∘C, 2 ∘C, and -20 ∘C,
respectively. The mass flow rate of the refrigerant is 0.9 kg/s .
The refrigerant quality at the refrigerator exit is 0.4.

appropriate units.
B)
Determine the rate of heat removal from the freezer.
Express your answer to three significant figures and include the
appropriate units.
C)
Determine the compressor power input.
Express your answer to three significant figures and include the
appropriate units.
D)
