Whoever thought of putting fresh and exhaust vents both in the balconies of tiny apartments was a real genius.

    btw, if the fans are off, does wind blow in air through the exhaust vents?
    Exhaust fans should have dampers to prevent intrusion of air when the fan is not running.

    Is it possible air being exhausted from a balcony near yours contains cooking odors that are being ingested by your ERV?
    • Electricity makes refrigeration happen.
    • Refrigeration makes the HVAC psychrometric process happen.
    • HVAC pyschrometrics is what makes indoor human comfort happen...IF the ducts AND the building envelope cooperate.


    A building is NOT beautiful unless it is also comfortable.

    also, approximately how long does it take for the air to completely exchange with all the ventilation off and the balcony door open, assuming no wind and just the stack related air exchange from the balcony door?

    yes, that is also a problem, but not as bad as the corridor.

    do fresh air vents have dampers too? (I mean do you get fresh air blown in with the erv off if it's windy?)

    How do I check if they do have dampers or not?

    Dampers.... They work when they work. Most spring loaded butterfly dampers are great when they are new. Add real world stuff like several years of exhaust 'crud', and they stick open, or closed. My experience is that they should be inspected periodically to ensure they are indeed functioning as designed.

    Gravity operated 'flappers' have to be positioned properly, or they don't work at all. Again, house maintenance personnel usually don't really care or know - you have to be your own advocate, and informed when you are a tenant. I hope we're providing some direction here for you.

    Where are they? Anywhere in line with the exhaust duct. That needs to be established, and notated for future reference.

    I don't know. I'm not really sure what a damper is to go look for them!

    Here is a common butterfly damper showing how it works on a you tube video.

    Here is what one looks like before it is installed. When installed, they are almost hidden in-line, so you have to 'feel' for them if they are in flex duct.

    oh, so they are right behind the fan, rather than near the exhaust vent outside. I see. Thank you.
