    Anybody have a picture of a condensor air deflector

    I have 2 horizontal machine room 5ft ex fans discharging into other refrig units
    and I'm trying to find a picture of an added sheet metal deflector to turn
    the air flow up. I've seen it done in many states maybe where a condensor
    or a cooling tower was installed incorrectly discharging into prevailing winds or
    another unit too close nearby but I haven't been able to find an actual picture
    on the net and my graphic skills on a paper napkin are not the best
    Recent elect rate increases here
    Any help is appreciated

    what are you trying to do? I don't understand ex fan. Is it your recuiculating exhaust off another condenser.

    Yes exhausting into other units. I tried to upload a drawing but it's too big for HVAC talk
    and I don't know how to reduce the size for upload
    Hot air blows horizontal out of machine room down a 6ft wide alley into 4 units inline
    50hp compressor room heat into 2 each 5 ft exhaust fans then into 2hp then 2hp then
    5hp then into a 71/2 hp
    Hussmann doghouse units in the alley all inline. Air temp last week was 95 going into the
    machine room and sometimes 125 into the last unit in alley
    Trying to find a picture for carpenter or sheet metal to make upward air deflectors
    I've seen cooling towers and big air cooled acs with these but can't find a picture now
    Thanks

    Yes beb and len recirculation big time but inline. I assume the downstream units were
    added years after the original machine room was built and due to a land locked situation
    the air gets reheated 4 times after leaving the machine room. The only option I know of
    is to deflect all discharges upward. The alley is maybe 40ft long
    Here is a link to the drawing at the top of the page if it opens for you
    as I can't get it to upload here on hvac-talk. Thanks for your interest
