Geothermal air conditioning is accomplished with a geothermal heat
pump, also called a ground source heat pump, abbreviated GSHP,
(alternately, ground source closed loop heat pump).
It is evidently futile to attempt to narrow the search to Arecibo.
Even restricting the search to Puerto Rico produces very meager
results. All of relevant sites tend to focus upon the Center for
Energy and Environmental Research of the University of Puerto Rico as

Geothermal Heat Pump Overview
"The geothermal heat pump, also known as the ground source heat pump,
is a highly efficient renewable energy technology that is gaining wide
acceptance for both residential and commercial buildings.
Geothermal heat pumps are used for space heating and cooling, as well
as water heating. Its great advantage is that it works by
concentrating naturally existing heat, rather than by producing heat
through combustion of fossil fuels.
The technology relies on the fact that the Earth (beneath the surface)
remains at a relatively constant temperature throughout the year,
warmer than the air above it during the winter and cooler in the
summer, very much like a cave. The geothermal heat pump takes
advantage of this by transferring heat stored in the Earth or in
ground water into a building during the winter, and transferring it
out of the building and back into the ground during the summer. The
ground, in other words, acts as a heat source in winter and a heat
sink in summer.
The system includes three principal components:
Geothermal earth connection subsystem
Geothermal heat pump subsystem
Geothermal heat distribution subsystem"
Geothermal Heat Pumps Make Sense for Homeowners
"Geothermal heat pumps are one of the most efficient ways to heat and
cool a home and provide hot water. More and more homeowners are
discovering the benefits of these systems, which tap the relatively
constant temperature of the Earth a few feet underground, for both new
homes and retrofits in existing houses.
Why a Geothermal Heat Pump?
The installation of a heating or cooling system is a decision that
will affect a homeowner's comfortand pocketbookfor years to come.
One option to think about is a geothermal heat pump (GHP), which is
one of the most cost-effective and longest-lasting heating and cooling
systems on the market. Plus, GHPs provide free hot water as a
byproduct of air conditioning for the household in the summer.
Also known as ground-source heat pumps or GeoExchangeSM systems, GHPs
provide many benefits to the homeowner in both new and retrofit
situations. Surveys by utilities illustrate a high level of
satisfaction with GHPs compared to conventional systems. In fact, more
than 95% of all GHP users would recommend a similar system to their
friends and family.
According to the Environmental Protection Agency (EPA), GeoExchange
systems are the most energy- efficient, environmentally clean, and
cost-effective space conditioning systems available (source: "Space
Conditioning: The Next Frontier," EPA 430-R-93-004, April 1993)."
Geothermal Heat Pumps for Medium and Large Buildings
"Business owners around the United States are installing geothermal
heat pumps to heat and cool their buildings. This well-established
technology offers benefits to businesses that range from increased
comfort for employees and customers to significant dollar savings in
energy and operation and maintenance costs.
Geothermal heat pumps (GHPs) are also known as ground source or water
source heat pumps and GeoExchangeSM systems. They use the relatively
constant temperatures of soil and water beneath the frost
linetypically 45°F to 70°F (7°C to 21°C)to provide efficient heating
and cooling all year long. The efficiencies achieved by these systems
are impressive and allow commercial users to save up to 50 percent
over conventional heating and cooling systems, plus they reduce
The environment also benefits when business owners choose geothermal
heat pumps. The U.S. Department of Energy's (DOE) Geothermal Heat Pump
Program has set a goal of two million units installed by the year
2005. Achieving this objective will save consumers about $400 million
per year in energy bills and reduce U.S. greenhouse gas emissions by
over 1 million metric tons of carbon each year."

Wat is Geothermal Heating and Cooling?
"The Power of Geothermal Heating and Cooling
Whats Buried in Your Yard?
With a geothermal heating and cooling system from ClimateMaster, your
lawn becomes a permanent power plant for your home.
How Does it Work?
The earth absorbs almost 50% of all solar energy and remains a nearly
constant temperature of 50°F to 70°F depending on geographic location.
Working with an underground loop system, geothermal heating and
cooling systems utilize this constant temperature to exchange energy
between your home and the earth as needed for heating and cooling.
In the summer, the system reverses and expels heat from your home into
the cooler earth via the loop system. This heat exchange process is
not only natural, but is a natural and highly efficient way to create
a comfortable climate in your home."
