[5] analyzed a R744-R717 cascade system from the thermodynamics point of view in order to determine the optimum condensing temperature of R744 in the low-temperature circuit. Bansal and Jain [18] evaluated the optimum cascade condensing temperatures of R744 for different refrigerants such as R717, R290, R1270 and R404A, which are in the high temperature circuits of a cascade system.

It must be noted that Co2 systems operate at high pressure and low critical temperature so special guidance must be followed in system design.
