Abstract
Device for extracting water from humid ambient air, the device including a conduit in which successively is incorporated: a compressor to compress the humid ambient air into compressed ambient air, a first condenser to dry the compressed ambient air into dry compressed air, an expansion valve or expander for expanding the dry compressed air into dry expanded air and a second condenser. The first condenser is further configured to direct the wet ambient air through it as coolant for extracting water from the compressed ambient air in a first stage via an outlet or the like. The second condenser is configured to direct the dry expanded air through it as coolant for extracting the water from the humid ambient air in a second stage by means of an outlet or the like.
Claims14
A device for extracting water from humid ambient air, the device comprising a conduit in which successively are incorporated:
- a compressor to compress a first stream of humid ambient air into compressed ambient air,
- a first condenser to dry the compressed ambient air into dry compressed air,
- an expansion valve or expander for expanding the dry compressed air into dry expanded air, and
- a second condenser,
- wherein the first condenser is further configured to direct a second stream of humid ambient air through it as a coolant for extracting water from the compressed ambient air in a first stage via an outlet, and
- wherein the second condenser is configured to direct the dry expanded air through it as a coolant for extracting additional water from a third stream of humid ambient air in a second stage by means of an outlet.
A method for extracting water from humid ambient air, the method comprising the steps of:
- compressing a first stream of humid ambient air into compressed ambient air;
- and
- drying the compressed ambient air into dry compressed ambient air by extracting water in a first stage from the compressed ambient air by cooling it by means of a second stream of humid ambient air;
- expanding the dry compressed ambient air into dry expanded air;
- and
- extracting water in a second stage from a third stream of humid ambient air by cooling it by means of the dry expanded air.
