For single refrigerants such as R22 and R134A, the isothermal line has no gradient in the saturated area, that is, the saturation temperature under certain pressure is the same at both the liquid side and the gas side. For R-404A History. R-404A rose to prominence in the late 1990’s with the phasing out of CFC and HCFC refrigerants like R-12 and R-502. There had to be a replacement for the Ozone damaging refrigerants of the past and the successor was the HFC R-404A that we all know of today. 404A’s reign however was short lived.20 psia. 10:1 is a compression ratio commonly found in refrigeration applications. If you are thinking about air conditioning, it is often around 3:1 or 4:1. Example 2: 200 psia = 20:1. 10 psia. In this example, the suction pressure drops by 10 psia, which doubles the compression ratio. At this compression ratio, a compressor designed for a 10: ...

R-410A has a GWP of over two-thousand whereas R-32 has a GWP of only six-hundred and seventy-five. While R-32 isn’t perfect it is a lot better then R-410A. That is why we are beginning to see a rise of usage of R-32 in the European Union and here in the United States as well.

R-407C is a zeotropic blend of R-32 (Difluromethane), R-125, and R-134a (Tetrafluoroethane). It is not a drop in replacement on R-22 machines. If you wish to use this product you will need to vacate all of the old R-22 out of the system. This is due to the R-22 systems using mineral oil and this HFC blend using POE oil.If, for example, the discharge temperature were 210˚ with a 150 psi head pressure, a 10 psi suction, and a 50˚ outdoor temperature, this would show an extreme undercharge.
