Does the average modern house air conditioner bring in air from outside, or just circulate the house air?
In other words, is outside air brought into the air conditioner, cooled, and then blown into your house, or is it air that’s already in the house, and cooled from that?
I ask because, if it is the second option, it wouldn’t seem that you could get any fresh air that way.
Thank you in advance for your help.
The air inside the house is recirculated and de-humidified (dried) and cooled by the conditioner. No outside air is used.
