Patent ID: 8857203

Claim:
A personal thermal regulation system, comprising: a personal liquid cooling garment, wherein the personal liquid cooling garment is configured to circulate a working fluid therein; a membrane evaporator configured to receive circulated working fluid from the personal liquid cooling garment, wherein the membrane evaporator is further configured to evaporate a portion of the received circulated working fluid; a chemical absorber in fluid communication with the membrane evaporator, wherein the chemical absorber is configured to receive a controlled flow of the evaporated portion of the received circulated working fluid from the membrane evaporator; a first control valve disposed to control the flow of the evaporated portion between the membrane evaporator and the chemical absorber; a second control valve disposed to vent the evaporated portion to an exterior environment based on an outlet temperature of the membrane evaporator; a controller in signal communication with the first control valve, the second control valve, and the membrane evaporator, wherein the controller is configured to vary the position of the first control valve and the second control valve in response to a received outlet temperature of the membrane evaporator.
