Geothermal cooling could save 2 million kilowatts a month at new Orange City schools

Published Jun 29, 2008
Geothermal, literally, means earth (geo) heat (therm). In other parts of the country, naturally warm air from beneath the earth's surface is used to heat homes and water. Volusia County Schools will use the technology to cool schools.

Drago said water from the Floridan Aquifer, which is a constant 72 degrees, will be sucked up through pipes to the surface plant. Warm air will be pushed over pipes containing the cool water. The air and water will exchange heat, leaving the water warm, and the air cooled.

Of the options available to save money on heating and cooling, the location of the Orange City schools favored geothermal cooling.

...millions of gallons of chilly water are flowing below the site toward Blue Spring, minimizing the possibility of intrusion or leaching that might occur as a result of temporary withdrawals for the schools' cooling system.
