This system would use, you guessed it, propane. The proposed system would not be break up so there would be no require for refrigerant piping heading among areas.
Like the other options it is suitable with POE lubricants and, like 407A and 407F, superheat will need to be checked and changes designed to your expansion valve.
They nonetheless Possess a relatively higher Global Warming Opportunity. R-32 is simply too flammable for lots of people’s taste. R-452B will more than likely be to high-priced for Many others. Who is familiar with what another option is going to be?
