A R32/CO2 cascade refrigeration cycle was analyzed thermodynamically, the results show that: Under given working conditions, there exists the best condensing temperature of the low-temperature circuit to make the maximum COP of the cycle. The lower evaporating temperature is, the lower the best condensing temperature of the low-temperature circuit is. Under the same evaporating temperature, COP increases and mH/mL decreases along with condensing temperature decreasing, under the same condensing temperature, COP decreases and mH/mL increases along with condensing temperature decreasing. To reduce the temperature difference in the cascade-condenser can increase COP and decrease mH/mL.
