An air conditioner is basically a refrigerator without the insulated box. It uses the evaporation of a refrigerant, like Freon, to provide cooling. The mechanics of the Freon evaporation cycle are the same in a refrigerator as in an air conditioner.improves in the existing building air-conditioning system automation the aspect.The energy conservation may say is the building character automatic control system starting point and the home to return to. It is well known, in the intelligent construction, HVAC (heating, ventilates and air conditioning) the system consumes to have to occupy the building consumption total energy enormous partial proportions,approximately about 50% ~60%.

conservation method, especially uses is in When the temperature outside begins to climb, many people seek the cool comfort of
indoor air conditioning. Like water towers and
power lines, air conditioners are one of those
things that we see every day but seldom pay
much attention to. Wouldn't it be nice to know
how these indispensable machines work their
magic? In this article, we will examine air
conditioners -- from small to huge -- so you
know more about what you're seeing!
The Many Faces of Cool
Air conditioners come in various sizes,
cooling capacities and prices. One type that we
see all the time is the window air conditioner.
Window air conditioners are an easy and
economical way to cool a small area. Most
people who live in suburban areas usually have
one of these in their backyard:
If you live in an apartment complex, this is
probably a familiar sight: Most businesses and
office buildings have condensing units on their
roofs, and as you fly into any airport you notice
that warehouses and malls may have 10 or 20
condensing units hidden on their roofs:
And then if you go around back at many
hospitals, universities and office complexes,
you find large cooling towers that are
connected to the air conditioning system:Even though each of these machines has a
pretty distinct look, they all work on the same
principles. Let's take a closer look.
The Basic Idea
An air conditioner is basically a
refrigerator without the insulated box. It uses
the evaporation of a refrigerant, like Freon, to
provide cooling. The mechanics of the Freon
evaporation cycle are the same in a refrigerator
as in an air conditioner. According to the
Merriam-Webster Dictionary Online, the term
Freon is generically "used for any of various
conditioner. According to the Merriam-Webster
Dictionary Online, the term Freon is
generically "used for any of various
nonflammable fluorocarbons used as
refrigerants and as propellants for aerosols."
This is how the evaporation cycle in an air
conditioner works (See How Refrigerators
Work for complete details on this cycle):
1.The compressor compresses cool Freon
gas, causing it to become hot, high-pressure
Freon gas .
2.This hot gas runs through a set of coils so
it can dissipate its heat, and it condenses into a
liquid.
3.The Freon liquid runs through an
expansion valve, and in the process it
evaporates to become cold, low-pressure Freon
gas .
4.This cold gas runs through a set of coils
that allow the gas to absorb heat and cool down
the air inside the building.
Mixed in with the Freon is a small amount
of a light weight oil. This oil lubricates the
compressor.
