Which affects my car’s energy efficiency more: raising/lowering the setting on my car’s air conditioner, or raising/lowering the fan speed? Is there a most-efficient setting?
In: Engineering
Fan speed does not really affect efficiency a lot. I’m not 100% sure on this, but I believe AC is either fully on or off, and temperature is more controlled by how much heat is added. The heat is neutral efficiency-wise, because it’s just the losses from the Engine. If you don’t want it in the cabin and turn it down, it’s redirected to go out.
