I heard a talk last week. The speaker referred to a new drop-in replacement for r22.

He said that it was a new mix of 3 gasses and that it could be topped up after a gas leak!

Is this possible? Surely, the 3 components will boil at different rates.

He then said that they have good results with DX but are having problems with flooded systems. A comment from the audience was that in the flooded system, the compressor pulls vapor from the accumulator and therefore will change the liquid concentration in the flooded evaporator.

But this contradicts the first claim?
