Integrated Flow Separator and Pump-Down Volume Device for Use in a Heat Exchanger

A system comprising:

• a compressor;
• a first heat exchanger in fluid communication with the compressor;
• and
• a first device in fluid communication with the first heat exchanger, the first device comprising:
• a first vessel comprising:
• a first vapor chamber;
• a first liquid chamber;
• and
• a divider separating the first vapor chamber from the first liquid chamber;
• a first vapor tube extending from within the first liquid chamber, through the first divider and the first vapor chamber to outside the first vapor chamber, wherein the first vapor tube includes first holes between an inlet and an outlet of the first vapor tube within the first vapor chamber;
• a first liquid tube extending from within the first liquid chamber to outside of the first liquid chamber;
• a first access opening in fluid communication with the first liquid chamber;
• and
• a first flow regulating device disposed within the first vapor tube to provide phase separation between a working fluid traveling between the first chamber and the second chamber within the vapor tube.
