Patent ID: 8302421

Claim:
A wearable personal air conditioning system comprising: a moisture exchange cartridge having a bundle of capillary tubes extending from a first bundle end to a second bundle end, said bundle being arranged to provide interstitial space between and among outside surfaces of the tubes, said capillary tubes being constructed of a polymer permeable to a liquid coolant, and a cartridge housing accommodating said bundle, said cartridge housing having an inlet for receiving air flow to the interstitial space and an outlet for exhausting the air flow; a sealant closing the interstitial space portion of the first end of the bundle while interiors of the tubes remain open at the first end for receiving a liquid coolant, the tube interiors being closed at the second end; a liquid coolant reservoir operatively connected to the bundle first end for presenting a liquid coolant to the tube interiors at the first end; and an air blower for supplying an air flow to the cartridge housing inlet, whereby relatively dry and warm air flow through the interstitial space can be cooled and moistened by evaporation of a liquid coolant at the outside surfaces of the tubes and exhausted from the cartridge as a relatively cool and moist air flow.
