Vapor recovery system for immersion cooled data centers

A method of operating a vapor recovery system, comprising:

• receiving a fluid vapor;
• condensing a first portion of a working fluid from the fluid vapor at a condenser;
• adsorbing a second portion of the working fluid from the fluid vapor at a scrubber;
• determining a composition of a processed fluid vapor after condensing the first portion of the working fluid and after adsorbing the second portion of the working fluid;
• if the composition is determined to have an amount of working fluid at or below a working fluid threshold, exhausting the processed fluid vapor;
• and
• if the composition is determined to have an amount of working fluid above a working fluid threshold, directing the processed fluid vapor back to the scrubber to desorb the scrubber.

A vapor recovery system, comprising:

• an inlet located at a first end of a fluid path configured to receive a fluid vapor to the vapor recovery system, the fluid vapor including vaporized dielectric working fluid;
• an adsorptive scrubber located on the fluid path and configured to adsorb at least some of the vaporized dielectric working fluid from the fluid vapor to generate processed fluid vapor;
• an exhaust located at a second end of the fluid path;
• and
• a valve located on the fluid path between the adsorptive scrubber and the exhaust and configured to selectively direct the processed fluid vapor to the exhaust and to a composition loop that connects back to the adsorptive scrubber to desorb, using the processed fluid vapor, at least some of the dielectric working fluid adsorbed on the adsorptive scrubber.
