Geothermal Air Conditioner – Cooling the air. To cool the air, take a 5-gallon bucket, place a fan on top, and cut out the bottom to allow warm air to pass through the cold conductive U loop. Depending on the soil composition, each loop will remain at around 18°C/64°F, regardless of the outside temperature. The loop does not necessarily have to hit groundwater, but having it interact with groundwater adds extra efficiency, as water contains more cooling energy for the same volume than thermal air. This becomes extremely useful in hot islands like Indonesia and Haiti, as it increases the unit’s efficiency on scorching days. For an average developing home of 500 sq/ft, only one ~10-meter loop is needed to prevent heatstroke in infants and elderly family members.
Dehumidification. Removing humidity is crucial in hot and humid environments, particularly for infants in developing nations, where high heat and humidity can be lethal. After the air has been cooled through the geothermal air conditioning process, it may still be close to 100% humid. To remove excess humidity, cut out two membranes of ordinary floral foam and fix them apart in a sealed plastic container. Allow the humid air to pass through the porous foam and out a standard air filter. It is important to swap out the wet floral foam every 2-3 days with sun-dried replacement foam to prevent bacterial growth. To further prevent bacterial growth, add trace amounts of salt and pure grain alcohol in the humidity bin. Alternatively, clean the container regularly to prevent bacterial growth. Ensure the container lid is firmly secured as pressure builds.
