    Help explaining a weird phenomenon in a heat pump!!



    I came across a situation that I do not understand.

    We have built a water heat exchanger heat pump, which uses an EMBRACO compressor and R-134a, and after some experiments and tweaks, we came across this situation. What is happening is that the temperature at the compressor discharge (leaving the compressor) is LOWER than the condensation temperature, according to the manometer temperature.

    Why might this be? We already sent all the manometers and thermometers to get re-calibrated, but we still get the same results.

    Attached are all of the results and measurements I got when performing this experiment.

    Liquid slugging
    It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.
