A steady-flow Carnot refrigeration cycle uses refrigerant-134a as the working fluid. The refrigerant changes fromsaturated vapor to saturated liquid at 60C in the condenser asit rejects heat. The evaporator pressure is 140 kPa. Show thecycle on a T-s diagram relative to saturation lines, and determine(a) the coefficient of performance, (b) the amount ofheat absorbed from the refrigerated space, and (c) the net workinput.

Problem 1 (Using thermodynamic tables)A large refrigeration plant is to be maintained at -12 C. It requires refrigeration at a rate of 120 kW.The condenser of the plant is to be cooled by liquid water, which experiences a temperature rise of 10 C as it flows over the coils of the condenser.
