R1234yf pressures.

All the literature I've read says 1234yf operates at lower pressures, bla,bla,bla but every one I've hooked up gauges to operate at 300 psi on the high side. Naturally the 100+ degree air temp isn't helping but it urks me that they run that high. I went knee deep into a compressor swap on a 2016 ram 1500 where a customer wanted to go cheap.R1234yf, or HFO-1234yf, was introduced in response to environmental concerns over the continued use of HFC-134a. This newer refrigerant is a hydrofluoro olefin (HFO). It has a much lower global warming potential (GWP) compared to HFC-134a. This refrigerant can only be used in newer vehicles whose air conditioning systems use R1234yf.AC R134A R1234YF Refrigerant Recharge Hose Kit, AC R134a 1234yf Gauge Set with Bullet Piercing Valves, R134a R1234yf Can Taps, Low Pressure Quick Couplers. 5.0 out of 5 stars. 2. 50+ bought in past month. $29.99 $ 29. 99.

CAUTOI N—DO NOT PRESSURE TEST OR LEAK TEST EQUIPMENTAND O/ R VEHICLEAI R CONDITOI NING SYSTEMS WITH COMPRESSED AIR . Mixtures of air and R1234yf refrigerant can be combustible at elevated pressures. These mixtures are potentially dangerous and can result in fire or explosion causing personal injury and/or property damage. R1234yf is about 18% lower than that of the R134a, as shown in Table 1. Fig. 2(a) and 2(c) also show that R134a has a higher final discharge pressure and temperature. As a result of marginally higher discharge pressure and lower suction pressure for R134a, the frictional losses in the R134a are marginally higher, as shown in Fig. 2(d).

The latest refrigerant technology is R-1234yf. 2,3,3,3-Tetrafluoropropene, or R-1234yf (HFO-1234yf), is the latest market replacement for R-134a automotive refrigerants.
