Consider a refrigeration cycle using r-134a to maintain temperatureof blood storage space at -15 degrees C. The cycle consists of foursteady flow components.

R-134a passes through an evaporator (a heat exchanger) removingheat from the refrigerated storage space such that it exits theevaporator as saturated vapor at -20 degrees C. (State 1)

The refrigerant then enters a compressor where it is compressed tosaturated vapor at 5 bar. (State 2)

After exiting the compressor, R-134a enters a condenser (anotherheat exchanger) where it rejects heat to surrounding air at 10degrees C and exits as a saturated liquid at 5 bar. (State 3)

The refrigerant exiting the condenser passes through a throttlingvalve so that its pressure drops before entering the evaporator(state 4).

The mass flow rate of R-134a is 3kg/min.

(a) Draw a diagram showing all the components of the refrigerationcycle labeling all relevant states. Sketch another schematicshowing the refrigeration cycle and all its energy interactionswith surroundings.
(b)What capacity (kW) compressor is required to operate thecycle?
(c)Determine the specific volume of R-134a at the exit of theexpansion valve (or inlet to the evaporator)
(d)Calculate the CPO of the refrigeration cycle
