On a hot day, it is certainly refreshing to enter a cool, air conditioned
building. Central air conditioning, by which entire homes and other
buildings are cooled and dehumidified, is popular in regions that are hot
and humid year-round, but is becoming popular in other areas as well.
Central air conditioning is also touted as a good remedy for individuals
with certain allergies.
Air conditioning is actually an old invention. Ancient civilizations
got hot and sticky too, and came up with some great solutions to keeping
their domiciles cooler. The ancient Egyptians, for example, used the
principle of evaporative cooling — the same principle we use in
refrigeration today — to cool their homes. In ancient Babylon,
a primitive form of air conditioning was accomplished by spraying water on
exposed surfaces. As the water evaporated, it absorbed the heat from
the dwelling. Romans and Persians ordered ice and snow brought into
their homes, and then their slaves fanned it in order to cool things down.
Modern central air conditioning systems are designed to cool
indoor living spaces during hot weather, and to improve indoor air quality
by filtering and dehumidifying the air. A typical central air
system is split between two major components — an outdoor condenser
and compressor plus an indoor evaporator mounted on an air circulation
system. The air circulation (or "air handling") system filters and
dehumidifies the cooled air, and distributes it, via ductwork, to multiple
rooms. Central air conditioning is generally quieter than individual
room air conditioners
that radiate their compressor noise closer to the living areas.
When a building is constructed, central air conditioning is often included
as part of the building's comprehensive heating, ventilating, and air
conditioning (HVAC) system. An HVAC system should be designed to
provide adequate cooling, heating, and ventilation, taking into account
the size of the building as well as its insulation efficiency and the
