Perhaps the most widely used air conditioners are the window air
conditioners. They are quite popular for heating and cooling in both
domestic and commercial premises. The basic advantage of a window air
conditioner is that unlike the central air conditioners and the split air
conditioners, it fits well in the window giving a good look and it does
not occupy any space of the room at all.

Moreover, window air conditioners do not need to be shifted every now and
then from one place to the other. However, like any other air
conditioning equipment, it produces noise, the intensity of which differs
with the type and size of the window air conditioners. Constant noise can
indeed be very disturbing and distressing to the home and surrounding
residents.

It is, therefore, advisable for the consumer to compare window air
conditioners by checking the sound power level labels on the unit or in
the literature specifications. The noise levels are often given in
decibel ratings and the higher the decibel level, the louder the unit
will be. The sound pressure increases by a factor of ten for every 10-
decibel increase. For example, 60 Decibels is 10 times louder than 50
Decibels and 100 times louder than 40 Decibels.

The compressor and the fan are combined in a single unit and mounted in
the window air conditioners and this is the source of all the noise in
the air conditioner. The other causes of noise could be worn bearings,
cabinet rattles, dirty or rusty fan blades, worn rubber mountings and
compressor wear. Regular maintenance can reduce the noise to some extent
but with the passing of time, there is bound to be an increase in the
level of the noise.

You should check whether your window air conditioner is vibrating or
producing a rattling noise and if so, then it is not a normal situation.
The reason for this can be improper installation or loose side panels.
If, however, you hear a scraping noise, you should either take the help
of an authorized service provider or you can also try to find out the
cause and repair it yourself.

The following steps can help you in tracking the fault and repairing it:

You should tighten the screws holding the front panel onto the unit.
You should check carefully the window all round the unit. You should then
turn the window air conditioner on and press your hand against the sash.
If you find that as you press your hand against the sash, the sound
changes in pitch, then you should put some wooden shims in the gap
between the window air conditioners frame and the sash. If, however, the
pitch of the noise changes when you press your hand on the glass, you
should use some insulating cellophane tape between the glass and the
frame. You might have to use putty if that does not reduce the noise.

If you feel that the sound is originating from within the unit, you
should take the unit out of the window and check to see if the fan blades
are bent. If so, just bend them back so that they match the others.

Portable Air Conditioners Ensure Economy And Convenience

With the onset of the damp weather, it becomes difficult to survive
without constant central air conditioning but that can prove to be quite
expensive. The answer to this problem is a portable air conditioner as it
has many advantages. It is easy to shift from one place in the home to
another and that makes a portable air conditioner the ideal cooling
system solution for your home, office or industrial site.

The portable air conditioners are easy and quick to i nstall, as they do
not involve any lifting or tearing up of windowsills. Moreover it can be
shifted very easily from one place in the home to the other. For taking
care of the hot spots in the central air conditioning, the portable air
conditioners are far more convenient than window air conditioners. It is
also ideal for window shapes, which present problems for installation.
There is nothing like portable air conditioners for use as a spot cooler
in the home.

A portable air conditioner is an excellent choice for saving money as
just one unit needs to be purchased and it can be shifted easily to where
you need it as it is mounted on castors and some can weigh only about 36
pounds. Moreover, as only one room is cooled at a time instead of the
whole house, the total energy consumption is very low as compared to
other air conditioning systems.

Another advantage of portable air conditioners is the energy efficiency
that they provide. The average efficiency is in the 8 to 10 range
although some are as high as 15, which is 50 percent better than most
older central air conditioners. The small size of the portable air
conditioners is very advantageous and as such it can fit in a corner or
against a wall. It functions like an effective dehumidifier if you do not
vent the warm exhaust air out through a window and its size is also the
same as that of a room dehumidifier.
In order to reduce humidity and allergies, even the small ones remove 35
pints of moisture per day from the room air. The portable air
conditioners also use the heat-exchange principle as the other air
conditioners to cool and dehumidify the air. The operating principle is
also similar to a window air conditioner as the room air circulates over
cold evaporator coils to cool and dehumidify it inside the unit. The room
air is exhausted outdoor after flowing over the hot condenser. There is
no chance of already-cooled indoor air escaping outside as two ducts are
now used.

Nowadays, you have electronic controls in most models and you can set the
desired room temperature, blower speed, start and stop timer, and
operation mode (cool, dehumidify, heat). The portable air conditioners
also have hand-held remote control with which you can conveniently change
all the settings as per your need.

The other features of portable air conditioners include a built-in air
cleaner with an optional charcoal filter and oscillating louvers to
distribute the cool air throughout the room. You can also switch off the
louvers to direct the flow of air towards yourself, if you so desire.
