At my aerospace job, we heat up the refrigerant tanks while charging with a heat gun. By heating the liquid in the tanks, it is turned into a vapor. I don't fully understand why we do this, but I think it's simply because vapor is easier to pull into the system than liquid. I hope I answered your question. It was kinda confusing.
