Cascade Techniques. CO2 cascade methods are most frequently subcritical devices which give lower-temperature (LT) refrigeration and reject heat to an upper cascade. DX cascade-subcritical CO2 systems are similar to a standard vapor compression cycle, with CO2 as being the refrigerant; the main difference is that the heat transfer capacity necessary to condense the superior-temperature/substantial-pressure CO2 vapor leaving the compressor right into a higher-force/higher-temperature liquid is furnished by an HFC refrigeration program, with the heat transfer happening within a cascade evaporator/condenser.
