Discovering Geothermal HVAC systems
The
word geothermal has two parts, GEO ( Earth ) & THERMAL (Heat ), we
can state that it is an HVAC system that capitalizes on drawing heat
from a building and depositing it to earth. In doing so it uses
significantly lesser amount of energy compared to a conventional HVAC system.
How does it works?
The Geothermal HVAC concept works like this, we take
the largely constant temperature of the Earth beneath our feet and
start from that point to begin heating or cooling our home or business.
What does geothermal system consists of?
Mainly
of two or three basic components, the earth coupled portion (also known
as collector), the load portion (the object or medium to be heated or
cooled) & usually a third portion that provides the remainder energy
for cooling or heating usually a mechanical system.
So what are the benefits of installing this technology?
Lower Operating Cost
Quiet Operation
Environment Friendly
Clean and Safe
Very long Life Cycle
Geothermal systems
require little maintenance. When installed properly, which is critical,
the buried loop can last for generations. The unit’s fan, compressor,
and pump are housed indoors, protected from the harsh weather
conditions, so they tend to last for many years, often decades. Usually,
periodic checks, filter changes and annual coil cleaning are the only
required maintenance.
Geothermal HVAC
Systems are becoming common features of Eco-friendly homes &
industries as a part of the green building movement.
Geothermal heating
and cooling systems are the most energy efficient HVAC systems in the
world today. Less is more; simple is better.
They work with nature and not against it,
Does this make sense? Let me know what you think…
