    Lenox Prodigy and ERV

    whats the purpose of the ERV ..... was it originally intended to help bring in fresh air to Smoking sections ?


    or do they still install them to go hand and hand with the MUA unit to help make positive pressure ?

    Lenox Prodigy and ERV

    The name sort of implies the function.

    Exhaust recovery ventilator

    So anywhere you need to exhaust anyways, you need to make the air back up.

    So its essentially an energy saver, as some of the heat energy will transfer between the air streams.

    Where the originally developed for improving air in smokey building? - maybe.

    Any energy recovery unit uses a media...sometimes silicon based.

    Think of it like a honeycomb with two separate paths for air to travel through the block of media.

    As air is pushed through the block of media out one pathway, simultaneously, air is drawn through the other pathway into the building. Since those two air streams pass by each other, heat is transfered (through the media) from the warmer air leaving, to the cooler air entering.

    So you essentially "recover" the heat you would otherwise lose by simply exhausting building air.

    This has about 12 air filters in front of the honey comb , and the Belts only last 6 months because if the 2 high torque motors , sometimes they snap , its such a pain in the ass

    If 1 belt snaps , the AC barely works

    I guess both , the RTU , and ERV , have to be running perfectly in time/sync

    The ones I've seen, the energy recovery ventilator is a separate unit that is the return air for the RTU. If the ERV stops, then the rtu doesn't have any return.

    Is this one a wheel, or just stationary media with blowers?

    If you're breaking belts on a heat recovery wheel, you may have bearings going out.

    This.

    Quite alot of opposing forces acting on the wheel. Damaged seals are often a result of worn bearings, check them too.

    No .. its not the type with the big ass honey comb wheel that slowly turns

    This has stationary long square honey comb

    When you are looking at the side of the unit , theres a door on the right , it has all of the filters in there , and you need a pull rod to get them

    Door on your left has the 2 blower motors , one on top draws in outdoor air , one on bottom draws in building air

    Im pretty certain its in the return air

    Im actually going there today for a Margarita machine , I can snap a pic

    Ah, gotchya. Some of them have wheels that are mounted horizontal and spin pretty fast..

    If you're losing belts on a standard blower, then you have something wrong, or the drive system is undersized for the HP.

    Man, you might wanna check that media. Looks like the door seals are shot.

    Looking at the dirt trails, you could have a plugged block of media.
