    Forget about the sub cooling with refrigeration. It is what it is. With a TXV your going to want to know what the superheat is. This is a cooler correct ? If the coil is at 20-25 degrees that would be correct for a 10* TD evaporator.

    The model # you gave is for the condensing unit. It may or may not be the original. Your charge will depend on several other factors. Unless you have worked on a piece of commercial equipment since it was new, you have to start at the beginning.

    If it's not the problem? Determine the problem then fix it. Otherwise you haven't learned antyhing and are nothing more than a parts changer. We have enough of those in our industry.

    Does your condensing unit have a receiver on it ? I did not see one on the model # you gave. Might have to do with the bill of materials though.
