Vapor recovery system for immersion cooled data centers

A method of operating a vapor recovery system, comprising:

• receiving a fluid vapor with an inlet positioned at a first end of a fluid path;
• condensing a first portion of a working fluid from the fluid vapor with a condenser located on the fluid path;
• heating the fluid vapor with a heat sink located on the fluid path downstream of the condenser;
• and
• with a chiller in thermal communication with the condenser and with the heat sink:
• cool the condenser;
• and
• rejecting waste heat from the cooling of the condenser to the heat sink for the heating of the fluid vapor with the heat sink.

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;
• a condenser located on the fluid path;
• an adsorptive scrubber located on the fluid path downstream of the condenser, the adsorptive scrubber including:
• an active scrubber;
• and
• an inactive scrubber;
• a heat sink located on the fluid path downstream of the adsorptive scrubber;
• and
• a chiller in thermal communication with the condenser, the active scrubber, the inactive scrubber, and the heat sink and configured to:
• cool the condenser to condense a first portion of a working fluid from the fluid vapor in the condenser;
• cool the active scrubber to absorb a second portion of the working fluid from the fluid vapor at the active scrubber, wherein the cooling of the condenser and of the active scrubber generates a waste heat of the condenser and the active scrubber;
• reject at least a portion of the waste heat to the inactive scrubber to heat the inactive scrubber and to desorb a third portion of the working fluid, adsorbed thereon, from the inactive scrubber;
• and
• reject at least a portion of the waste heat to heat the heat sink and to heat the fluid vapor at the heat sink.
