    not very likely and not the problem here.

    Sounds under charged IMO. Said the charge was weighed in, so how much was weighed in? if it was 4 pounds yea, if it was 15 well maybe not. If the evap is hissing it's not getting liquid.

    I am curious to what he is trying to actually describe, the mismatch makes sense but then again I never seen or heard of that desparity yet. Interested to hear the sound to know it if I heard it in the future hissing sounds crazy. Not baggy on you just interested on the units operation, seen alot of crazy stuff just in trade college but a weird hissing with normal operation??? not sure

    please torque the wheels on my car to negative 35 psi!!!!


    hahahahahahahaha

    you just exposed your weakness.....you are an engineer

    you prolly know how to draw a 10 inch pipe that goes thru a 8 inch hole!!!!!!

    omgh

    and now a physics major has to ask us if a leak can happen one way????

    also said physics major also talks about positive pressure????like negative pressure exists?????

    then whines about being heckled???

    You should be embarrassed by these comments you've made. You're giving this guy a hard time and you are completely 100% wrong. He made the comment about physics because you obviously have no idea what you're talking about.

    Have you ever worked on a low pressure chiller? I'm sure you haven't but I'm here to tell you that you have the option to read pressures in PSI or absolute which means you can and will get negative PSI readings.

    What's your definition of pressure? You should look it up because pressure in not defined as being positive or negative because pressure can exist in either state.

    What's -14.7 PSI? Oh, I guess in your world it doesn't exist.


    Ever heard of low pressure refrigerant? Do you have a CFC card? They're called low pressure refrigerants because they operate in a vacuum, which is low pressure! I've never heard them referred to as vacuum refrigerants, have you? Ever worked on a R-113 chiller? I have and it's ALWAYS in a negative pressure, even when the chiller is running.

    Oh, and it is absolutely possible to have a leak when positive pressure is applied and not have a leak when a vacuum is applied (vacuum being pressure at less than atmospheric pressure) or vice versa, but I doubt that is the problem here.

    Yep. It is possible to have a "one way" leak.

    Man The Internet is filled with crazy info. I knew I read some where in a book that some chillers work on Negative preasures. I geuss if it's not from an approved "source" Take it with a grain of salt and never let it second geuss yourself cause some Guy wants to rip some new guy.

    I am glad I read the whole thread so I know im not crazy

    Sometimes these things are just a matter of terminology and personal experience. The key is to remember that we are all learning, every day, IF we are doing this right.

    I really need an explanation as to how you can have a leak under pos. Psi And not neg. Psi
