Room Air conditioners

Most people don’t realize how their central air conditioner actually works. They think that
an air conditioner functions by pumping cool air into their home. But your air conditioner
actually removes warm air and recirculates it as cool air. An air conditioner is basically a
refrigerator. It uses the evaporation of a refrigerant, like Freon, to provide cooling. An
central air conditioning system includes both the cooling and heating of air and cleans
the air as well as controls the moisture level.
There are a number of ways you can cool our home, but with any central air conditioning
system the basics are the same; you will have a method of removing warm air to create
cool air, a way to distribute the air to all of the rooms in your home, typically your duct
system, and a way to control or regulate your system (thermostat).
The first component of your air conditioning system is temperature control. When the air
temperature rises above a preset level on your thermostat, the thermostat sends a signal
to the air conditioner. This signals the air conditioner that it is time to turn on.
The compressor (which is controlled by the thermostat) is the “heart” of the system. The
compressor acts as the pump, causing the refrigerant to flow through the system. Its job
is to draw in a lowpressure, lowtemperature, refrigerant
in a gaseous state and by
compressing this gas,
raise the pressure and
temperature of the
refrigerant. This highpressure, hightemperature gas then
flows to the condenser
coil.
