Claims9
A multi-stage refrigeration system, comprising:
- an eductor in fluid communication with a first vapor line and a liquid source;
- a flashdrum in fluid communication with the eductor, the flashdrum connected to a second vapor line, a liquid line at a bottom of the flashdrum and a two-phase fluid line;
- a first expansion valve connected to only the liquid line and a chilled two-phase fluid line downstream from the flashdrum and the first expansion valve;
- another flashdrum in fluid communication with the chilled two-phase fluid line and connected to the first vapor line;
- and
- a pump positioned upstream of the eductor and in fluid communication with the liquid source.
