I'm a bit confused on how proper design incorporates AC units (Window Style or Portable). Both appear to exhaust only very little to the outside, but this isn't really the question or important here I guess.
The question is: How is the constant introduction of fresh air handled, when the fresh air being introduced into the room may be very warm (IE 90 degree air from the outside during the summer)?
So, if an AC is cooling a room constantly, and fresh air is also being brought into the room from the outside (constant air exchange), then isn't this somewhat defeating the purpose of the AC? That is, I can't really imagine an AC unit cooling a room faster than say a 6" or 8" Can Fan is bringing warm air in (passively).
I realize that fresh air from the outside is not 100% necessary in that things will still work. That is, instead of exhausting air out, while introducing fresh air in (as in the example above) the room room could instead simply use the AC unit, while scrubbing and re-circulating the same scrubbed air. I realize this works, but I thought that the proper design was to always have new air being introduced. So, assuming proper design, how is fresh air incorporated into an AC'd room?
