R1234yf pressures.

Jul 4, 2023 · In this article, we will explore the recommended pressure ranges for R1234yf and discuss factors that may affect these pressures. R1234yf Operating Pressures The normal operating pressures for R1234yf refrigerant typically range between 30 and 38 psi (pounds per square inch) on the low-pressure side and 150 to 220 psi on the high-pressure side. The GWP value of R1234yf is four, which is well below the absolute maximum value of 150. This means that it breaks down much faster in the atmosphere, thus not destroying the ozone layer. Unfortunately, there is a slight drawback in that R1234yf is a bit flammable and also runs at a higher pressure and at higher temperatures.
