Transportable modular water vapor condensation apparatus

Apparatus for condensing liquid water from ambient atmospheric air containing water vapor, the apparatus comprising:

• a housing having a first end defining a first air opening, an opposite second end defining a second air opening, and first and second opposed side walls extending between the first and second ends;
• a third air opening in at least one of the first and second opposed side walls;
• a water condensing unit in the housing and configured to receive a flow of ambient atmospheric air through the housing between at least one of the first and second air openings and the third air opening, the water condensing unit being configured to cool the ambient atmospheric air at least to its dewpoint, thereby condensing liquid water from water vapor in the ambient atmospheric air, the water condensing unit comprising a pre-cooling section and a condenser section;
• and
• first and second door assemblies operable selectively to open and close the first and second air openings, respectively, wherein the first door assembly is at the first end of the housing, and the second door assembly is at the second end of the housing;
• wherein the water condensing unit is located in the housing so that, when at least one of the first and second air openings is open, at least a portion of the flow of air between the at least one of the first and second air openings that is open and the third air opening is passed first through the pre-cooling section and then through the condensing section, whereby water vapor in the portion of the flow of ambient atmospheric air passing through the water condensing unit is condensed as liquid water.
