Dehumidifier
First Claim
Patent Images
1. A dehumidifier, comprising:
- a first channel for transporting air at a first pressure;
a second channel for transporting air at a second pressure lower than the first pressure; and
a graphene oxide barrier separating the first channel and the second channel;
wherein the relatively lower pressure of air in the second channel causes water vapour to be drawn out of the air in the first channel, and wherein the first channel and the second channel are elongate and helical.

Abstract
A dehumidifier comprises: a first channel for transporting air at a first pressure; a second channel for transporting air at a second pressure lower than the first pressure; and a graphene oxide barrier separating the first channel and the second channel. The relatively lower pressure of air in the second channel causes water vapor to be drawn out of the air in the first channel.

14. A method of dehumidifying air, the method comprising:
-
providing a dehumidifier having a first channel, a second channel and a graphene oxide barrier separating the first channel and the second channel; generating a flow of air at a first pressure in the first channel; and generating a flow of air at a second pressure in the second channel, the second pressure being lower than the first pressure, such that water vapour is drawn out from the air in the first channel, through the graphene oxide barrier and into the second channel; wherein the air flowing in the first channel is oxygen-depleted, and the method further comprises; receiving, in a water tank, the water vapour drawn out from the oxygen-depleted air.

15. A method of dehumidifying air, the method comprising:
-
providing a dehumidifier having a first channel, a second channel and a graphene oxide barrier separating the first channel and the second channel; generating a flow of air at a first pressure in the first channel; and generating a flow of air at a second pressure in the second channel, the second pressure being lower than the first pressure, such that water vapour is drawn out from the air in the first channel, through the graphene oxide barrier and into the second channel; wherein the temperature of air flowing in the second channel is lower relative to the temperature of air flowing in the first channel.
