|AIR CONDITIONING BASICS
Two-thirds of all homes in the United States have air conditioners. Air conditioners use about 5% of all the
electricity produced in the United States, at an annual cost of more than $11 billion to homeowners. As a result,
roughly 100 million tons of carbon dioxide are released into the air each year -- an average of about two tons for
each home with an air conditioner.
Air conditioners employ the same operating principles and basic components as your home refrigerator.
Refrigerators use energy (usually electricity) to transfer heat from the cool interior of the refrigerator to the relatively
warm surroundings of your home; likewise, an air conditioner uses energy to transfer heat from the interior of your
home to the relatively warm outside environment.
|evaporator. The condenser, a hot outdoor coil, releases the collected heat
outside. The evaporator and condenser coils are serpentine tubing surrounded
by aluminum fins. This tubing is usually made of copper.
A pump, called the compressor, moves a heat transfer fluid (or refrigerant)
between the evaporator and the condenser. The pump forces the refrigerant
through the circuit of tubing and fins in the coils.
The liquid refrigerant evaporates in the indoor evaporator coil, pulling heat out
of indoor air and cooling your home. The hot refrigerant gas is pumped
outdoors into the condenser where it reverts back to a liquid, giving up its heat
to the outside air flowing over the condenser's metal tubing and fins.
|Throughout the second half of the 20th century, nearly all air conditioners used
R-12 as their refrigerant, but because those chemicals are damaging to
Earth's ozone layer, R-12 production stopped in the United States in 1995.
Nearly all air conditioning systems now employ R-22 as a refrigerant, but
these are also being gradually phased out, with most production and
importing stopped by 2020 and all production and importing stopped by 2030.
Production and importing of today's main refrigerant for home air
conditioners, R-22, began to be phased out in 2010 and will stop entirely by
2020. As these refrigerants are phased out, ozone-safe refrigerants like
R-410A are expected to dominate the market, as well as alternative
refrigerants such as ammonia.
