Room Air Conditioner For Confined Areas Of Your Home
By Joel F Mornigstar
A room air conditioner is the type of cooling device that is
designed to be best used in a smaller home or in an apartment
setting. They are rather small units that are intended for use
in a single room and install into a window, although some people
will also cut a hole into an exterior wall to install them.
Portable air conditioner units have also recently been brought
to market. These portable units are mounted on casters so they
can be rolled from one room to another and they use a flexible
hose for venting, so no installation is required.
Cool The Air Within An Area Of The Room
The purpose of air conditioning equipment for a room is to cool
the air within a small, confined area and they are not intended
to be used as a "whole house" air conditioning system.
They are most often used in houses or apartments where people
are renters; therefore, they are not permanently installed and
can be removed and taken to a new location if the occupant moves.
Most of the room air conditioner units come with built-in control
panels, either on the face of the unit or on the top near the
front, positioned so that the user is able to easily see and adjust
the controls. Typically, there are two sets of controls, one for
adjusting the temperature setting and the other to control the
fan velocity.
Remove The Heat From The Air
Most people are not aware that room air conditioning units do
not "technically" cool a room. It is more correct to
say that room air conditioners remove the heat from the air and
then moves it elsewhere to where the unit has been vented.
A pressurized refrigerant, R-22, flows through the air conditioner
unit when it is turned on. While the unit is on, the condenser
will pull the refrigerant gas into the air conditioning system
and then pressurize it, which raises the temperature of the gas.
This heated, high-pressure gas travels next to the condenser coils,
which are located on the outdoor portion of the unit where the
fans distribute the heat that has collected.
The cooled gas then becomes condensed into a liquid, which moves
to the interior part of the room air conditioner to the evaporator
coils. At this point, these coils can absorb the heat that is
in the room. The fan then moves the air throughout the unit. The
thermostat controls the cycling of this process to maintain the
desired temperature in the room.
Newer Air Conditioners Have Electronic Touch Pads
Some room air conditioners have mechanical controls, such as
knobs and push buttons. The newer air conditioning units are controlled
with electronic touch-pads that tend to provide more functionality
and can regulate the mode the units operate in, the temperature
set point, a timer for automatic shut off and powering on, and
various other conveniences, most of which are designed to make
the unit as energy efficient as possible.
To make it easier and clearer for consumers to select the best
room air conditioner, all types of air conditioners carry a label
with a rating of their energy efficiency. This is a service of
the US Department of Energy and is called the Energy Star rating.
The EER, or Energy Efficiency Rating, is derived by taking the
cooling capacity of BTUs and dividing that by the watts of energy
used. In order to carry an Energy Star rating, the model must
have an EER of at least 10 percent higher than competing models.

Little Known Air Conditioner Facts....
What is better: a window unit or central air?
That is a difficult question and largely
depends on how big of an area you will be cooling down. If you
live in a loft or a one bedroom home or office you may be better
serviced by a window unit. Large spaces are inefficiently cooled
by window units.
It would take several to cool down each
of the rooms in the home. Central air, on the other hand, can
be pumped in from a unit located outside or inside and used to
cool the entire house at once. It may be more cost efficient to
use a central air unit to cool down a home or large office.
