The p ? T behavior of 2,3,3,3-tetrafluoroprop-1-ene (R1234yf) was measured from T = (232 to 400) K with pressures up to 10 MPa using a two-sinker densimeter. The measurements extend from low-density vapor to compressed-liquid states, and include the extended critical region. Vapor pressures from T = (250 to 366) K were also measured.Fundamentally, R1234YF systems will run at a slightly higher pressure, and the gas itself is actually flammable. Not super flammable, but it will burn slowly if you really tried to light it on fire (don’t). This means that all AC service shops will be slowly getting the new tools, machines, and training required to service R1234YF cars.R1234yf Pressure Temperature Chart R1234yf Temperature (°C) Pressure (barA) Pressure (barg) Pressure (psig)-70 0.11 -0.90 -13.06-68 0.13 -0.88 -12.82-66 0.15 -0.87 …
