    Note the data plate specifies 10degrees sub cool AT the evaporator. Your subcool measurement outdoors doesn’t take into consideration the heat gain from the long uninsulated liquid line. Especially important in attic evaporators with multi story homes.

    How much additional charge was added?
    Why not add an additional temp probe for the OAT and then it will be automatically input?
    It is a heat pump sitting flat on the pad. I guess there is no freezing happening in your area and if this goes into defrost the water will not freeze on the outdoor coil?

    Excellent demonstration! Does bleeding air out of the line as a vapor go against best practices due to the need to keep the blended 410A mixture ratios correct? I would think that bleeding lines with a blended refrigerant would be best done using a liquid. Maybe that’s not a concern.

  • @piezomotor
    @piezomotor Год назад

    Thank you for this video. Originally the blue gauge showed the saturation temperature of 20 degrees F (Pressure 43 PSI R22). At the same time the temperature I measure on the blue line next to the charging port is 80 degrees F. Thus my Superheat is 80 F - 20 F = 60 F. The pressure at the red gauge before charging was 200 PSI that corresponds to the temperature of 102 F. When I charged the system from the R22 recovery bottle, the Superheat changed 75 F - 26 F = 49 F. my red At the same time my red gauge after charging shows the pressure 225 PSI or it is the temperature 106 F and I measured the temperature of the high pressure pipe was 106 F. Question- is my system is overcharged now of I should continue charging it?

    Sorry but I am confused. In the video you said that the large line was he true suction line. I thought that most units had a true suction line, usually on the same panel about the 2 service ports but sometimes inside the unit.
    I thought that the service port suction line changed in heat mode, and that you had to be hooked up to the other suction port (true suction) in heat mode.
    I thought that the small line liquid port remained the same in both modes.

I do home inspections and that would certainly be a red flag on the paperwork and I don't like red flags anymore than anybody else does. Lot of unnecessary work.

Fast forward 5 years later and I just recently finished HVAC school .The other day I plugged my Testo 550 gauges and couldn't get more then 5 degrees of subcool ,data plate recommends 10 but my superheat was @ 8-12 and have a 20 degree split from my RA AND SA vents .Outdoor temp was 105 (Vegas heat baby) I don't wanna keep adding refrigerate just to get the recommended subcool and risk flooding my evaporator ,and returning back to the compressor .So I do have a starved condenser .I told my instructor and he feels the unit it to large but which I agree . What are the risk of having a starved condenser ? Do you feel I should let it be ?

      Only pure molecule refrigerants are supposed to be charged as a gas. The mix refrigerants (the ones that start with 4) are mixtures of different molecules. The mix needs to be added to a system as a liquid to maintain correct mixture of the molecules.
