    Post nelson11

    All right new to the forum. I have a problem I can't figure out
    15 ton chiller we had a leak. We evacted the system, fixed the leak.
    vaced the system, and recharged. High pressure is 130# low 25# machine says it takes 22 pounds of r-22. We put over 30 pounds in
    and the sight glass still bubbles. The bubble never went away during charging. air temp is about 90 degrees.
    Ideas????

    Yep
    Don't step on my favorite part of the Constitution just to point out your favorite part.

    Political Correctness is forced on you because you have forgotten decency.

    Technically speaking, they are all heat pumps.

    Is that a mathematical approach?
