The invention discloses a CO2 transcritical refrigeration system recooling gas-liquid separation device and method, two-stage throttling is adopted, and a recooler and a gas-liquid separator are arranged after first-stage throttling. The recooler takes low-temperature saturated gas shunted from an outlet of the evaporator as a cold source to cool a two-phase mixture subjected to primary throttling; saturated liquid separated by the gas-liquid separator enters the evaporator after being subjected to secondary throttling, and saturated gas flows back to an inlet of the recooler. On the basis of two rigid constraints, namely evaporation pressure reference and charge volume fixation, the equivalent condensation pressure which is physically locked is introduced into the transcritical cycle for the first time, so that the system obtains fixed high-pressure reference. Thermodynamic derivation shows that the recooling ratio is determined by evaporation pressure and uniqueness, and the operation is completely physically adaptive. Simulation results show that the COP under the air conditioner working condition reaches 3.038, is improved by 38.2% compared with that of a basic system and is superior to that of an existing split-flow supercooling technology (17.62%). The compressor only needs to maintain simple frequency modulation of evaporation pressure without a complex algorithm. The device is suitable for CO2 transcritical systems such as air conditioners, heat pumps and freezing and refrigerating.
