    Assuming the TXV is adjusted correctly, the saturation temp must be about -4C or lower. This gives us an evap TD of at least 12C/21.6F. This seems excessive.

    And for the frost to continue all the way to the compressor, we may be looking at a much lower saturation temp and much higher TD before the compressor decides to unload.
