Air-Conditioning
Your Home Comfortably and Efficiently
The summer of 221 A.D. was a scorcher in Rome. While
most of the populace suffered, the Emperor Heliogabalus
could command satisfying relief: he ordered a thousand
slaves into the mountains to bring back a caravan
load of snow to cool the imperial gardens.
Although the Emperor's way of beating the heat is
an interesting sidelight in history books, he was
not by any means the father of air conditioning. Centuries
before him, Egyptians learned to store water in reservoirs
on house roofs to wet down the outside walls. The
dry desert winds evaporated the water, cooling the
interiors. In India, almost everybody knew that a
wet mat, hung in the wind across an open door, cooled
the incoming breeze.
These rudimentary systems applied principles still
useful today: first, as substances melt or evaporate,
they absorb heat from whatever is nearby; second,
comfort demands both temperature control and air circulation.
But, for most of civilization, a completely satisfactory
way to make people comfortable in hot weather remained
elusive. In 1833, a doctor named John Gorrie hit on
a pleasing but still primitive way: he blew air over
buckets of ice to soothe the fevers of malaria patients
in Florida. Gorrie, among others, saw a market for
a machine that could make ice. Around 1850, he and
other inventors were at work on machines that put
the cooling power of evaporation to work under controlled
conditions.
In one typical design, ethyl ether, a refrigerant,
was pressurized by a compressor and then released
in coils, where it evaporated, freezing the water
around the coils. This basic refrigeration cycle laid
the foundation for the development of modern refrigerators,
as well as room and central air conditioners like
those described on the following pages.
One major problem remained unsolved. Humidity control,
it became apparent, was as crucial a factor in regulating
interior climate as temperature and air circulation.
Moisture carried by hot air condensed on the cold
coils of early refrigerators, reducing humidity slightly;
but no one could control it.
A young engineer, Willis Carrier, set out to solve
this problem, and in 1902 he succeeded, devising a
machine for a Brooklyn printer who had difficulty
because his paper swelled on humid days. By controlling
both the temperature of refrigerator coils and the
volume of air moved by fans, Carrier found he could
also control the humidity. He chilled the air, thus
forcing most of its moisture to condense; then he
mixed this chilly, dry air with uncooled air to release
a comfortably cool and dry mixture. This system is
the one universally used today.
The price of this comfort is measured by the electricity
bills, which, as anyone who pays them knows, rise
implacably. One way to conserve electricity is to
match the capacity of air-conditioning units to cooling
needs. Too small a unit cannot remove enough heat
to cool a room. Yet, too large a unit quickly chills
the air, but runs so briefly that the slower dehumidifying
process cannot remove enough moisture to make the
air comfortably dry.
