At steady state, a refrigeration cycle removes 800 kJ/min of energy by heat transfer from a cold space maintained at -15o C and discharges energy by heat transfer to its surroundings at 20o C. If the coefficient of performance of the actual cycle is 80 percent of that of a reversible refrigeration cycle (ideal) operating between thermal reservoirs at these two temperatures (β = 0.80 βmax), determine: a) Coefficient of performance; b) Power input to the cycle, in kW; c) Heat rejected to the surroundings. Draw sketch and show all calculations.

Question
At steady state, a refrigeration cycle removes 800 kJ/min of energy by heat transfer from a
cold space maintained at -15o C and discharges energy by heat transfer to its surroundings at
20o C. If the coefficient of performance of the actual cycle is 80 percent of that of a
reversible refrigeration cycle (ideal) operating between thermal reservoirs at these two
temperatures (β = 0.80 βmax), determine:
a) Coefficient of performance;
b) Power input to the cycle, in kW;
c) Heat rejected to the surroundings.
Draw sketch and show all calculations.
