Car Air Conditioning Repair : Car Air Conditioner Parts: The Evaporator


Hi my name is Mark Delgado with American Auto
Service for expert Village. Once in the evaporator
coil it will obsorb the heat from the interior
of the vehicle. Because the evaporator coil
is deep inside the dash I just want to show
an example of what it looks like. So the refrigerant
comes into here in liquid form and as it comes
in here under low pressure it removes the
heat. Comes out as a gas on the other end
which returns to the compressor to be compressed
again. The cycle starts over. So that’s the
basic way that the airconditioner works.They
have a couple of different control vices.
This vehicle uses an expansion valve. Like
a chevrolet or a lot of american cars use
what’s called an orfice tube. Which is inline
which creates a restriction.
