Question about HOW a car AC works...

I love my 2000 Civic's AC system... its is still super frosty after 9 years.

I have a question about exactly HOW it works. There is a round dial for adjusting the temperature from coldest to hottest. Does that dial simply adjust how much of the air is passed through the heater core, or is it smart enough to also control the duty-cycle of the AC unit? I'd like to think turning it to 3/4 cool means the AC is running less, and not just fighting the heater core.

Hope that makes sense... anybody know?
