SOLVED: The next few problems consider the cascade refrigeration cycles shown below. The compressors are adiabatic and 90% efficient. The operating fluid is refrigerant 22 (chart attached). HX is an evaporator for the upper cycle and condenser for the lower cycle. MARK YOUR ANSWERS CLEARLY ON THE CHART AND SUBMIT WITH YOUR WORK. The dotted line is the boundary used in problem (a). Find H1: mark it on the plot and label it; and report here the values of H1 and Ti.
