So the air my car is cooling is 20% fresh, as in the ouside air. Then the remaining 80% is air in the cabin that is re-cooled? I'd like to have something like newer cars with recirc. The pod line that is being closed, what does it control? Howe does it recirculate air only when the compressor is on?
Thanks
David
