Abstract
A device for adsorbing water vapor from a gas stream. The device can be incorporated with an enclosure or garment in such a manner so as to enable water vapor to be adsorbed, thereby decreasing the relative humidity in the micrlimate surrounding the user. The water adsorption device is light-weight, has a high mass and volumetric energy capacity. A desiccant material is included within the water adsorption device to adsorb water vapor and a phase-change material is located in thermal communication with the desiccant to increase the loading capacity of the desiccant and maintain a cool gas stream by extracting the heat of adsorption from the desiccant.
Claims17
A personal cooling device, comprising:
- a) a garment adapted to be worn by a user and comprising a garment inlet adapted to receive a gas stream flow and pass the gas stream flow to an interior of said garment when worn by a user;
- and
- b) a cooling device in fluid communication with said garment inlet and adapted to provide a gas stream flow to said inlet, said cooling device comprising:
- i) a cooling device inlet;
- ii) a cooling device outlet adapted to provide a gas stream to said garment interior;
- iii) at least a first flow channel disposed between said cooling device inlet and said cooling device outlet;
- iv) a desiccant in vapor communication with said first flow channel;
- and
- v) a phase-change material in thermal communication with said desiccant.
