    My Brother has an air conditioner that sits in the window of his apartment. He called me tonight and asked me if the vent should be set to open or closed. I have no idea?

    I was thinking that if it is really hot and humid outside that he should set it to closed.

    Any ideas?

    I believe that is like the recirculated air in your car. Open means you get outside air, closed means you get inside air.

    Thanks. I looked it up and it seems that I had the right idea. If you want it to be a cold as possible, keep the vent closed. [​IMG]

    (Unless you are using it in during the Winter) [​IMG] [​IMG]

    Thanks Philip

    sounds like you got it. On my old unit the vent was a small trap door that sucked air in, but didn't draw ALL the cooled air from outside, just added some fresh air to the output. [​IMG]

    Usually the idea setting is half open/half closed for recirc/outside air. This maintains a good balance of new air but also keeps the unit from working too hard.

    This was from a friend who used to design HVAC systems for large buildings; they tried to keep their mixing boxes so they would pull half/half. It also works really well in cars, provided you have a mixing control instead of just one button.

    Well, a central unit draws all of its aire from inside and recirculates it. I'd think this would be more efficient for a widow unit as well. The unit would be cooling already cooled air instead of the hot outside air. I believe the vent should be open only if the unit is being used as a fan only and not cooling.

    My brother tried it out, it blows colder with the vent closed. He has a separate knob for "fan" & "cool".

    He has now found that having the vent closed produces cooler air. (With the other knob set to "cool" of course)

    Thanks again guys!
