###### Question details

An ideal vapor compression refrigeration system uses R-22 as the working fluid. The condensing temperature is 120°Fwith 15°F sub-cooling, and the evaporating temperature is 30°F with 20°F superheat. The system produces 15tons of cooling effect. Sketch the cycle on a p-h diagram and determine:a)The Carnot COP b)The compressor suction and discharge pressures inpsigc)The refrigerant mass flow rate, lbs./hd)The ideal COPe)The ideal input power of the compressor(Btu/h), and the power/ton(Btu/ton.h)f)The actual COP calculated from manufacturer’s performance tables if a scroll-type compressor is used
