A central air conditioner is a major investment and important to maintaining
the comfort of your home. This is why it is good idea for you as a homeowner
to have a reasonable understanding of how your system works.
This will allow you to perform some basic maintenance tasks yourself, as
well as to spot major problems when they happen. This knowledge will also
help you better understand the information a professional relates to you
about the system.
The heat transfer process that allows an air conditioner to work requires
that the refrigerant change its state and density during the process.
The compressor, which is located in the outside part of your air conditioning
system, compresses the gas, increasing its density and temperature.
The condenser is another part of the outside unit and is the component
that the compressed gas travels to. The condenser functions like the radiator
on a car, by transferring the heat from the compressed gas to the outside
air via a series of metal fins. As this happens, the gas is momentarily
converted to liquid. The liquid is then expelled through a small hole
into the line leading to the home, where the pressure drops and the liquid
becomes a gas again.
The evaporator is inside your home and is the part that actually cools
the air inside your home. As the gas passes through the fins in the evaporator,
a fan blows air over them to create cold air that then travels throughout
your home via your ductwork system.
An air conditioner is not a simple piece of equipment, but understanding
at least the basics will benefit you in many ways. If you have any further
