geo-thermal vocabulary
Aquifer--an underground body of water. Closed System--geothermal system which has a closed loop of water flowing around the building that has never been in the aquifer or lake. Cooling Tower--large outdoor machine that cools water by making mist. Geothermal--also known as geothermal. A system of using the earth's temperature to benefit heating/cooling of buildings ( or electrical power generation). Heat Pump--air conditioning unit that heats and cools in about the same way using DX. DX--conventional refrigeration system used for cooling buildings. Heat Exchanger--engineered product designed to transfer temperature from one fluid to another (air is a type of fluid). Open System--a geothermal system in which water from the earth flows through the heat pump system. This is often isolated using a heat exchanger, but still considered an open system.Sustainable--capable of existing over long periods of time without complications. Variable Frequency Drive (VFD)--a device that makes motors turn lots of different speeds instead of just one. Also known as a variable speed drive (VSD).

Geothermal Myths
1. Geothermal is completely sustainable. (Depends). Geothermal in Florida uses the stable temperatures of the earth to benefit (not eliminate) mechanical cooling and heating processes. There will always be electricity needed for compressors and pumps ( in Florida). As geothermal grows in popularity, the effect on the ground water temperatures remains to be seen, but the vastness of the Floridian aquifers and the fact that they drain out into the sea has to be factored in. Geothermal in other parts of the country can be completely sustainable. 2. Geothermal is always the best system. (false). Geothermal has an undisputed advantage where heating and cooling occur at the same time. Cooling towers, for example can boast better performance during Florida winters. Multiple ductless systems at times have the advantage. Geothermal is not as conducive to high outside air as other types of systems. 3. Well drillers are experts who should be allowed to do their own thing. (False). While well drillers are the local experts on the aquifer systems, they are not engineers and have no workable knowledge of interfacing the well pump with the controls or the connected equipment. 4. Variable Frequency Drives solve all pumping problems. (false). Used correctly, VFD’s are powerful ...
