CO2 cascade system is a compound system, with CO2 as the refrigerant of low temperature stage, with other refrigerant in high temperature stage, which are two separate systems. The two stages are connected by the condensing evaporator, while the evaporator of the high temperature stage is also working as the condenser of the low temperature stage.
