Central Air Conditioning Brings Cool Air To Your Home
By Joel F Mornigstar
Every year as summer sets in and the temperatures start to rise,
people are reminded about how terribly uncomfortable the temperatures
can get inside of homes and offices that are not air conditioned.
Usually, when the weather heats up there is a rush of people searching
for ways to stay cool and comfortable.
Many people look to central air conditioning to make their homes
or offices a place where it is possible to comfortably work, play,
relax and sleep. These centralized systems are ideal for cooling
large spaces where a room air conditioner is just not enough to
do the job.
A Split System
A centralized air conditioning system does its job by utilizing
a "split system," which is able to condense the air
as well as compress it. Additionally, these systems use an evaporator
that is connected to the mechanism that handles air, such as a
forced-air furnace.
The entire unit is then put together as one complete system and
installed exteriorly, usually on the roof of a commercial building
or in a mechanical unit outside of a house.
Central Air Conditioning
When central air conditioning begins functioning, the cooled
air is blown through the edifice by fans via the ductwork that
has been installed, allowing the air to flow to the different
areas in the building. The temperatures are controlled either
with the use of a central control unit, several units to control
different zones, or individual control units that are placed in
each room.
However, there is also the possibility that some centralized
air conditioning systems do not come with such controls. In these
instances, the controls must be purchased at an additional cost
and should be installed at the same time as the complete unit.
It is important to clarify this upfront with company that is selling
and installing the unit so that there are no surprises during
the installation process.
Keeping The Noise Outside
One of the reasons why most homeowners prefer centralized, air
conditioning equipment is that these systems are able to keep
the noise associated with running the air conditioning outside.
Even the newer room air conditioners can be rather noisy, especially
when running at night in bedrooms.
Central air systems position the equipment that is responsible
for the majority of the noise on the outside of the house. This
allows the interior of the home to stay nice and quite even though
the air conditioning unit might be working hard to keep things
cool.
Installed When A Building Is Under Construction
Central air conditioning tends to be a fairly complex system
and the equipment is typically installed when a building is under
construction. These heating and air conditioning systems supply
the heating, cooling, air filters or air purifiers, and ventilation
as needed to keep the environment of the home or office building
comfortable and healthy. A centralized system utilizes supply
and return ducts that are placed throughout the structure in order
to properly circulate air.
If you are considering installing a new central air conditioner
or simply need to replace an existing one, then make sure that
the contractors who bid on the job perform a detailed "cooling
load calculation" so that the proper system for your home
will be installed.
Avoiding Oversized Equipment
It is best not to use a simple "rule of thumb," which
tends to result in oversized equipment. At the same time, they
should not simply replace the old system with a new unit of the
same size. The reason for this is because the existing system
may have been the wrong size to begin with, or the home may have
had added insulation or more efficient windows put in since the
original system was installed.
Air conditioning manufacturers are required to get their equipment
tested for how energy efficient it is and it is then given a rating.
This is a requirement under federal law. Central air conditioning
is given a SEER rating, which stands for Seasonal Energy
Efficiency, while heat pumps carry a HSPF rating, referring to
Heating Seasonal Performance Factor. Look for models with the
highest SEER or HSPF rating, which means they are most efficient.

Little Known Air Conditioner Facts....
When was the first air conditioner developed?
This is a tricky question because there have been
cooling fans in existence since the 2nd century when a Chinese inventor
by the name of Ding Huan created the first rotary fan. The Romans used
aqueducts and cooling towers to pump water into buildings to help cool
the air. This was a very expensive way to cool the buildings and homes
of the wealthy.
It was not until 1820 that the British inventor
Michael Faraday found out that compressing and liquefying ammonia could
invent ice and chill the air when it evaporated. This compressor technology
was taken a step farther when Dr. John Gorrie created ice to cool the air
around his patients. In fact Dr. Gorrie envisioned large scale air conditioning
systems that would cool cities but alas, his dream died and it was not until
fifty years later that the air conditioner unit came to be.
