Question:

A cascade system with one refrigeration cycle operating with R-410a has an evaporator at −40◦C and a high pressure of 1200 kPa. The high-temperature cycle uses R-134a with an evaporator at 0◦C and a high pressure of 1200 kPa. Find the ratio of the two cycle’s mass flow rates and the overall COP.
