Sustaining our Atmosphere and Climate
Your Term: [ground-source heat pump]
When temperatures are freezing or extremely hot, it is essential to have a place with
conditioned air where humans can be comfortable, safe, and healthy. With the increasing
population, energy consumption has increased. Traditional heating and cooling methods require
the use of fossil fuels and pollutants that damage the ecosystem. Ground-source heat pump
systems (GSHP) is a renewable heat energy source in use by multiple business facilities and
personal homes for heating and cooling exchange. The earth has a stable temperature over 6 ft
underground that can be cooler or warmer than the temperature above ground level (Bensel &
Carbone, 2020). The sun’s thermal energy is stored in the earth's soil layers. GSHP’s utilize this
stored energy and temperature difference with unique underground multiple piping systems that
can go horizontal and vertical. Water or an environmentally safe liquid with heat transfer
properties is pushed through these pipes. The water takes heat in the pipes from the ground
around the pipes, or the ground takes heat from the water in the pipes depending on the
temperature inside the building. It is then transferred to the air inside the building to heat or cool
(Xuli, Jing, Feng, Liang, & Lei, 2020). Some engineers have made units that integrate solar
collection, power generation, water heating, and tubing designs into the GSHP, which has
increased the system's efficiency and maintained energy costs (Coskun, 2020). GSHP units are
even used for safe driving conditions to protect from icy conditions by heating highways during
cold winter months (Zhao, Zhang, Chen, Su, Li, & Fu, 2020). Another significant usage of
GSHP is in regulating temperatures in greenhouses used to grow food (Harjunowibowo, Omer,
& Riffat, 2021).
The best use of GSHP is keeping us safe from harmful climate temperature changes and
not harming the environment around us. GSHP is an excellent solution to keep us warm or cool
without contaminating the environment and affecting the ecosystem around us (Zou, Pei, Wang,
& Hao, 2021). As society moves toward renewable energy, GSHP is being accepted as a source
that can be used with other renewable sources to reduce the need for nonrenewable resources.
The energy used is small compared to the massive amount of output. Although GSHP has not
been researched to its full potential, it is part of our present and future (Wang, Li, Xia, Yang,
Hou, & Zhang, 2019). The reduction of carbon and other harmful gases from the use of fossil
fuels will allow cleaner air and slow global warming. The heat from the sun inside the earth will
provide a safe environment for all while still giving us energy (Kose & Petlenkov, 2016). The
economy is growing at a tremendous rate, and the need for power for everyone is high. The
ground in some areas receives more solar energy, and therefore the temperature difference from
the ground is closer to the air above. GSHP systems can be designed to work in areas where
cooling is needed more than heating (Widiatmojo, et, al. 2021). GSHP is in its infancy, and more
research is required to utilize its full potential.
We can support renewable energy policies looking for zero-emission renewable energy
sources like GSHP. Policies that reduce the cost for low income to install energy-saving systems.
We can install GSHP and other energy-efficient devices when building new homes or buildings
and receive tax credits. GSHP systems can be installed on lease for less cost. Carbon gases can
be reduced faster by replacing nonrenewable sources with renewable sources. (Iea, 2021). We
can support research to make renewable energy more affordable for everyone. It may not be
possible to stop or collect all the pollutants causing climate change and the cost to do so is more
than installing GSHP that runs off the power, which can be sourced from renewable sources
(Erickson, 2021). Every renewable energy source that replaces a nonrenewable one gets us a
little closer to saving the planet.
