11-17 An ideal vapor-compression refrigeration cycle that uses refrigerant-134a as its working fluid maintains a condenser at \( 800 \mathrm{kPa} \) and the evaporator at \( -20^{\circ} \mathrm{C} \). Determine this system's COP and the amount of power required to service a \( 150 \mathrm{~kW} \) cooling load. Answers: \( 3.83,39.2 \mathrm{~kW} \)
