The Two main applications of Geo-Thermal Energy:
- Using the heat from the earth to create
electricity or to provide direct services such as hot
water heating or warming of the greenhouses.
- Using the thermal mass of the green soil
or the ground water to drive the heat pump to which can
be used for either heating or cooling applications.
Uses Of Geo-Thermal
Energy:
Geo-Thermal Energy is not only used for heating, but also
can be used for cooling, humidity control and even water
heating. When heating, the earth acts as a heat source,
when cooling it acts as a heat sink. It all depends upon
the geothermal characteristics (i.e. temperature and heat
quantity).
How does Geo- Exchange Systems work?
Geo Exchange System provides space conditioning, heating,
cooling and humidity control. They may also provide water
heating, either to supplement or replace conventional water
heaters.
Geo Exchange Systems work either by moving heat, rather
than by converting chemical energy into heat like a furnace.
Every Geo System has three major sub systems or parts.
- A Geo thermal heat pump to remove the
heat between the buildings and the fluid in the earth
connection.
- An earth connection for transferring the
heat between its fluids and the earth.
- A distribution subsystem for delivering
heating or cooling to the building.
Each system may also have
a de-super heater to supplement the building's water heater,
or a full demand water heater to meet all the hot water
needs of the building.
In heating mode, the heat
is extracted from the fluid in the earth connection by the
geothermal heat pump and distributed to the home or building
- typically through the system of air ducts. Cooler air
from the building is returned to the geothermal heat pump,
where it cools the fluid flowing to the earth connection.
In cooling mode, the process
is reversed. The relatively cool fluid from the earth connection
absorbs heat from the building and transfers it to the ground.
Is Geo Exchange System new?
Not really. The basic technology has been around for more
than 20 years, and many homeowners and businesses have been
enjoying the benefits of Geo Exchange for much of that time.
Is Geo Exchange System costly?
It depends on how you measure the cost. While they do cost
more to install in homes than conventional systems, because
of the ground loop piping. Geo Exchange systems typically
have the typical lowest life cycle cost of any heating or
cooling system. Moreover, the installation costs will decline
substantially in recent years. The more the builders and
contractors offer Geo Exchange Systems; the industry will
develop innovative ways to install the systems faster and
more efficiently. Geo Exchange systems are a sound investment.
The amount they save the homeowner every month in energy
costs is more than enough to offset their higher installation
cost, extra savings on repair, maintenance, and hot water
bills. The energy efficiency of the Geo Exchange System
adds value to your home.
