Actual vs. reversible Refrigerator Cycle
At steady state, a refrigerator whose coefficient of performance is 2.5
( = heat removed from cold reservoir divided by work needed )
removes heat from its freezer compartment at 0oC at a rate of
6000 kJ/h and discharges heat to the surrounding at 20o.
Please answer the following questions :
- Determine the actual power input to the refrigerator.
- Determine the necessary power inpout if you could operate a
reversible refrigerator cycle between the same temperatures and
removing again 6000 kJ/h from the freezer compartment.
