5. THE EARTH IS THE SOURCE OF
HEAT IN WINTER…
Outdoor air
design temperature:
40°F in winter
50°F
60°F
Insulating layer of earth
A geothermal heat pump takes heat from the earth
during winter and transfers it into the building
6. …AND AN EFFICIENT PLACE TO
REJECT HEAT IN SUMMER…
Outdoor air
design temperature:
100°F in summer
72°F
60°F
Insulating layer of earth
A geothermal heat pump cools the building in
summer by rejecting heat into the earth
9. WORKING OF G.H.P
An antifreeze solution is circulated through plastic
pipes buried beneath the ground for closed loop
systems. The fluid gathers heat from the earth and
circulates it through the system and into the
building. During the summer, the system reverses
itself and pulls heat from the structure and places it
in the ground. This process creates free hot water
in the summer and produces a considerable
savings on hot water in the winter
11. ADVANTAGES OF G.H.P:
Simpler in design and maintenance
Does not require a unit outside exposed to the
weather
Longer equipment life
They use less refrigerant
DISADVANTAGS OF G.H.P:
Higher initial cost due to piping or drilling of a well
Lack of trained and experienced designers and
installers less efficient system is install
12. ENVIRONMNTAL IMPACTS OF G.H.P
Geothermal heat pumps always produce less
greenhouse gases than air conditioners, oil
furnaces, and electric heating
The fluids used in closed loops may be designed to
be biodegradable and non-toxic, but the refrigerant
used may be chlorodifluoromethane, which is
ozone depleting substance.
Open loop systems that draw water from a well and
drain to the surface may contribute to aquifer
depletion, water shortages, groundwater
contamination, and subsidence of the soil.
13. ECONOMICS
Geothermal heat pumps save money in operating
and maintenance costs
Although initially more expensive to install than
conventional systems, properly installed GHPs
deliver more energy per unit consumed than
conventional systems.
In the summer cooling period, the heat that is taken
from the house is used to heat the water for free,
which saves money for heating water
15. CONCLUSION
Using Geothermal Heat Pump Green house gasses
emissions can be minimized
Geothermal heat pumps are highly efficient heating
technologies that allow for reductions in CO2
emissions
Heat pumps utilize significantly less energy to heat
or cool a building than alternative heating systems
GHP systems generally have a higher first cost
than conventional HVAC systems, but the energy,
maintenance and replacement savings can result in
paybacks
