    Greetings,

    Some techs charge non-TEV systems by watching the
    point suction line pressure starts increasing. As refrigerant
    is added, the temperature of the suction line decreases, as
    more refrigerant is added the temperature of the suction
    line starts to increase because the suction pressure increases.
    Some techs stop charging at this point. Is this a valid method
    of charging non-TEV A/C split-systems? Probably not, but why not?

    Cheers,
    michael

    Because, by the time the suction temp stops decreasing, yu are already overcharged. To make the suction line temp start to increase, you will have a gross overcharge - maybe 40% above full charge or more.

    Again, you are posting technical information for discussion in the non-professional forums.

    Due to site rules, we are unable to discuss technical information with the general public. Thread closed.

    Thank you JR

    cobaltfjord,

    So everyone on this forum site will know. You have repeatedly ignored the posting of our Moderators when asked NOT to post technical information in the Residential Area.

    So everyone will know, you will be given one more chance. You have already had 4. Any postings of technical information in the Non-Professional areas will be your last posting on this website.

    This is about as clear, plain and simple as it gets.

    (thanks again JR)
