The mostly used central air
systems are split air conditioning systems. It contains an outdoor cabinet with
compressor, condenser coil and an indoor evaporator coil. It has installed in
conjunction with furnace or air handler. The compressor pumps a chemical which
is called refrigerant through the system.

Central air systems flow into
cool air via a system of supply and go back to ducts. Supply ducts and
registers (i.e. openings in the walls, flooring, or ceilings protected by
grills) carry cooled air from the air conditioner to the house. This cooled air
turns into hotter because it circulates via the home; then it flows back to the
central air conditioner thru return ducts and registers. Air conditioners help
to dehumidify the incoming air, however in extremely humid climates or in cases
in which the air conditioner is oversize, it may no longer achieve a low
humidity. Strolling a dehumidifier for your air conditioned domestic will
growth your electricity use, both for the dehumidifier itself and due to the
fact the air conditioner will require extra energy to cool your house.
A preferable alternative is a
dehumidifying warmness pipe, which can be added as a retrofit to most existing
systems. Combustion gases are generated
via the use of the burners on your furnace and passed via a heat exchange. Air
from your central home blows at some stage in the heat exchanger to be heated. It
is then blown through a system of ducts to distribute around your home. Sooner
or later of heat seasons your heating device works along with your central air conditioners.
Air is cooled because it’s blown over your air con unit’s cooling coil,
frequently attached to the air circulating fan of the furnace, after which sent
thru the same air ducts within the direction of your private home.
Once warm air inside your house
blows across the indoor evaporator coil, its heat energy transfers to the
refrigerant in the coil. That transfer, in turn, “cools” the air. The
refrigerant is pumped lower back to the compressor wherein the cycle starts
again. The heat absorbed through the refrigerant is moved outside your own home
even as cooled air is blown interior. Moisture that contributes to humidity is
also condensed out of the air.
Types of Central Air Conditioners
A central air conditioners could
be either a packaged unit or split system unit.
If we consider packaged central
air conditioners then the compressor, condenser and evaporator, all are located
in one cabinet which is usually situated on your roof or on any concrete slab
just next to the foundation of house. These types of air conditioners are used
in small commercial buildings. Air supply and return ducts come from indoors
through the house’s outside wall or roof to connect with the packaged air
conditioner, which is usually placed outside. Packaged air conditioners often
include electric heating coils or a natural gas furnace. This combination of
air conditioner and valuable heater gets rid of the want for a separate furnace
indoors.
Now if we go to Split air
conditioners, in a split air conditioner unit, an out of doors metallic cabinet
includes the condenser and compressor, and an indoor cupboard includes the
evaporator. In lots of split air conditioner systems, this indoor cabinet
additionally incorporates a furnace or the indoor part of a heat pump. The air
conditioner's evaporator coil is established inside the cabinet or fundamental
deliver duct of this furnace or heat pump. If your house already has a furnace
but no air conditioner, a split-system is the maximum low-priced valuable air
conditioner to put in.
As compare to room air
conditioners central air conditioners are more efficient. Buy energy efficient
air conditioners if you want to save energy and money. It reduces energy use of
your central air conditioning system.
Few common Problems
The air conditioning system will
not operate at all
The air conditioning system is
working but no cool air comes out
The AC is not blowing air
Leakage of water from the AC
Air Conditioner Makes Noise
The compressor is noisy during
start up
The air conditioner fuse keeps blowing
or the circuit breaker trips
Few things to keep in mind
while installing Central Air Conditioners
· You air conditioners should be environment
friendly which means it should be installed in such a way that it reduces
impact on the environment and is highly energy efficient.
· The air conditioners system should be installed
in such a manner that it is successfully control humidity and gives out a
comfortable and cool indoor air.
· However, proper installation should take care of
all the fact that it throws out stale air and other pollutants from the room
and brings pure and fresh air.
