 | Compress a gas
 | the gas becomes denser and hotter |
|
| Remove some of the heat
| the beauty of the gasses used as refrigerants is that they
will then condense into a liquid |
|
| Spray the liquid through a small orifice to decrease the
pressure
| another beauty of refrigerants: Lowering the pressure
turns them back into a gas
 | The ultimate beauty: When a liquid turns into a
gas, heat is released and the gas becomes cold |
|
|
| Flow the cold gas through a "radiator" (just a
length of pipe with radiating fins attached) |
| Pull air over the cold fins to make the air cold |
| Blow the cooled air into the car |
