Nitrogen LiquefierWorking principle
Utilizing a cryogenic mixed refrigerant throttle refrigerator, the nitrogen liquefier operates on a regenerative multi-component mixed refrigerant throttle refrigeration cycle. By selecting high, middle, and low boiling point pure components, it forms a multi-component mixed refrigerant system. This ensures effective cooling across different temperature zones, seamlessly transitioning from ambient temperature to a chilly -196 °C,achievingthe goal of nitrogen liquefaction at -180 °C under 0.6 MPa pressure.
