    Awesome. I see so many "technicians" that get confused with that discharge. Hopefully this will keep them on their toes. To add to that. Just had this today that the filter dryer was in the unit, had 1 tech misdiagnosed because the blockage was in the filter dryer that's in the unit (hello goodman). Thank you and good luck.

    Thanks for the video. Good job as always. Very helpful. I Work on a building with Trane package units without liquid line access port and I always guessing the subcooling with the discharge pressure and liquid line temperature. Did not know about that rule of thumb 10 to 15 psi pressure drop.

    I'd love for you to dive more into that flow to mass ratio that you touched on.
    I'm having trouble wrapping my head around why discharge temperatures go up when refrigerant is low. I know that that is the case but I can't understand why.

    It's why I always weighed in charges on package units. Awesome videos sir. You make me miss the trade. Wish more people like you were as dedicated to it and not just out to screw people like most I see in the area I live in. Just had a friend that let big multistate company install their unit and they installed in attic, worst install I've ever seen and after 3 failed inspections walked away and my friend said at least he didnt have to pay for the job. I said still you left with a unit that is going to give you trouble for years. Just recently his bedroom ceiling fell in due to unit not level and froze up and drained onto ceiling, unit has been in 7 months. In having to go back and rip out and reinstall this winter when it's cooler since he has to help and we both cant deal with Florida attic heat in August anymore due to age.

    I always enjoy and learn from your video. Where can I find the pressure temp chart for discharge superheat vapor -is the condensing saturation pressure corresponding with my discharge superheat temp. The example. If I have 190 psi condensing pressure, equivalent to 97 °F, and discharge superheats of around 195°F( just the guess), I can't find a superheated vapor temp pressure chart.

  • @dario6749
    @dario6749 Год назад +1

    Actually the pressure in the discharge and liquid line should be the same because high pressure from the discharge is pushing against the liquid in the condenser and gives you the condensing temperature. On the other hand this is theoretically speaking I do believe you would have some pressure drop in the condenser.

    Hey Bud when it comes to a package unit sometimes liquid lines don't have access ports. We are forced to use the discharge line access port. Which will be a completely different reading on the subcool. Can you do a video explaining why this this is wrong to do? Thank you.

    I was building a dehumidifier from scratch and was installing a service port. I accidentally installed it on the discharge side instead of the liquid, and my teacher goes and tells me it doesn't matter because the pressure drop across the condeser is unmeasurably small. That class is screwed.
