The
role of air conditioner is to move heat from inside of one’s home to the
outside, which provides cooling in the process. Air conditioners blow cool air
into the home by pulling the heat out of that air. The air is cooled by blowing
it over a set of cold pipes known as evaporator coil. This performs similar to
cooling that occurs when water evaporates from human’s skin.
The evaporator
coil is filled with a special liquid known as refrigerant, which changes from liquid
to a gas as it takes up heat from the air. The refrigerant is pumped outside
the house to another coil where it gives up its heat and changes back into a
liquid. This outside coil is named as the condenser since the refrigerant is
condensing from a gas back to a fluid similar to moisture on a cold window.
A
pump, known as compressor plays the role of moving the refrigerant between the
two coils and to change the pressure of the refrigerant in order that all the
refrigerant evaporates or condenses in the suitable coils.
The
energy to work out all of this is used by the motor that runs the compressor.
The entire system normally provides about three times the cooling energy that
the compressor uses. This odd fact occurs since the changing of refrigerant
from a liquid to a gas and back again allows the system to move much more
energy than the compressor uses.
Thank you for posting the in-depth explanation of how air conditioners actually cool. That was an interesting read. I love my air conditioner, but never really understood how it worked to cool down. I am looking forward to reading more in-depth blog posts like this from you. Keep up the good work!
