    YCWL end bells

    Anyone know of a reason why the condenser end bells on a York YCWL can't be swapped end to end? The question has the local Johnson/York rep stumped.

    Just by looking at the Condenser refrigerant piping and the way Condenser water connections are that woud be my reason for not allowing the swap they build it for a reason that way.

    It is not exactly cheating, I prefer to consider it
    creative problem solving.

    Perhaps the rifling in the tubes. I can't see how that would make a tremendous difference, but it is something to consider, right?

    This has been going on for quite some time. Had one several years ago that needed to be swapped to facilitate piping, and I was told no by the factory. When I asked why, all I got was a blank stare (if you can get a blank stare over the phone). Never did get an answer. I told 'em that there was no possible way that it could make a difference, and that if we got the job, we would swap them and all would be ok. Unfortunately, we didn't get the job, so I can't say for sure............

    This has only been going on since jci took over, so are you sure "method" has anything to do with it, and it's not just madness?

    Madness yes because there is more of the deer in the head light stare then ever before.

    Except for enhanced tubes, I can't think of any reason why a flooded cooler would care which direction the water was going.

    On some Trane units endbells can't be switched because of our active oil return system. Oil will migrate towards the cooler temperature. The bolt patterns on the endbells are different so they can't be swapped. RTWD 134a Screw chiller.

    There is no heat transfer reason that inhibits the exchange of the water boxes on the condenser, as long as you keep the condenser water inlet on the bottom and the outlet on top. The reason you can΄t do it physically, is that the tubes in the horizontal center of the closed water box side are not even with the tube sheet. The separation sheet welded inside between condenser water in and outlet would interfere with the condenser tube overlap.
